Executive Summary The Lower Boreal Highland subregion is found elevationally above the Central and Dry Mixedwood subregions in two ecosections (boreal and foothills). The boreal ecosection is defined by ecodistricts that are influenced by a boreal climate and boreal physiography. These ecodistricts include: Cameron Slope, Cameron Hills Upland, Caribou Slope, Caribou Upland, North Birch Upland, Birch Upland, Peerless Upland, Stony Mtn. Upland, Crow Lake Plain, Buffalo Head Upland, Wadlin Upland and Russell Upland. In contrast the foothills ecosection includes ecodistricts that are closer to the foothills climate and physiography and were previously classified within the Lower Foothills subregion (Ecodistricts of Alberta 1995). These ecodistricts include Chinchaga Plain, Clear Hills Upland, Milligan Upland, Notikewin Plain and Rainbow Lake Plain and are located in the Northwestern part of the province. The foothills ecosection is dominated by lodgepole pine forests and has little presence of jack pine. In contrast the boreal ecosection is the major zone of hybridization for jack pine and lodgepole pine and both species are present. The hairy wildrye ecosite is also found within the foothills ecosection, but was not described within the boreal ecosection. The hairy wildrye ecosite is described in both the Upper and Lower Foothills subregions (Beckingham et al. 1996). This guide represents the current analysis of 482 plots described in the Lower Boreal Highlands subregion. The boreal ecosection includes 227 plots that represent 37 community types. These types are split into: A. Native grasslands 2 community types described B. Native shrublands 6 community types C. Deciduous types 8 community types D. Mixedwood types 8 community types E. Conifer types 13 community types. The dominant plant species, canopy cover, soil and environmental conditions are outlined for each type. The foothills ecosection includes 255 plots that represent 47community types. These types are split into: A. Native grasslands 2 community types described B. Native shrublands 9 community types C. Deciduous types 9 community types D. Mixedwood types 12 community types E. Conifer types 15 community types. The dominant plant species, canopy cover, soil and environmental conditions are outlined for each type.

Acknowledgements Landscape classification is the process of breaking the landscape into definable and manageable pieces through a hierarchical classification. In the early 1990’s the forested landscape of Alberta was classified using a well organized hierarchical system (Archibald/ Beckingham / Klappstien). Unfortunately this left about 50% of the remaining natural landscapes of the province unclassified. Starting in the late 1990’s rangelands undertook efforts to classify the rangelands of Alberta. A need for consistency across the province was recognized. Therefore a hierarchical classification that built on the forested classification was used for all forest dominated subregions in the province. These classifications involve taking large amounts of vegetation, soils and landscape inventory data taken from the ECOSYS database and compiling the data into succinct descriptive summaries for each ecological site, ecological site phase and plant community within a subregion. In 2010 funding was provided by Policy and Planning Division, Alberta Environment and Parks in order to produce hard copy pdf documents from the ECOSYS website.

Introduction and Background The province of Alberta is covered by a broad spectrum of vegetation regions from prairie in the South, to alpine vegetation in the mountains and dense forests in the Central and Northern parts of the province. These broad vegetation regions have been classified into 6 natural regions and 21 subregions for the province (Natural Regions Committee 2006). Each of the regions consists of groups of plant communities which are influenced by environmental conditions and human impacts. Intensive management of these regions requires the ability to recognize the vegetative communities that have similar productivities and respond to disturbance in the same way. These vegetative communities are highly regarded by most resource managers for their ability to provide a wide variety of benefits. They are a classic example of multiple use land, providing summer range for livestock, prime habitat for many species of wildlife, productive watersheds and recreational areas. The purpose of this guide was to develop a framework that would easily group the ecological sites and vegetative community types in the Lower Boreal Highlands Natural Subregion of the province. Ecological site classification helps to organize our current understanding about ecosystem function. This organization is achieved by grouping research plots into similar and functional units that respond to disturbance in a similar and predictable manner. The ecological site classification system outlined in this document organizes ecological information into a format that facilitates understanding and provides a structure for ecologically based management. The system has been developed primarily as a field tool to complement the user's knowledge about ecological site classification, soil description, and plant identification. The objectives of the ecological site classification are: 1. to facilitate the application of ecological information to decisions on a wide variety of activities within the realm of land resource management 2. to facilitate the collection and organization of information to expedite the development of resource management applications and decision support systems 3. to promote communication among resource managers and between managers and the public 4. to provide a common basis for integrated planning, and 5. to reduce resource management costs by integrating ecological information into the decision-making process. This guide builds on the work outlined in the Field guide to Ecosites of Northern Alberta (Beckingham and Archibald 1996) for the Boreal Highlands subregion. In 2006 (Natural Regions Committee 2006) the original Boreal Highlands subregion was split into the Upper Boreal Highlands and Lower Boreal Highlands subregions. This guide outlines the analysis of 482 plots described in the Lower Boreal Highland subregion. The purpose of this guide was to develop a framework that would easily group the vegetative community types in the Lower Boreal Highlands Natural Subregion of the province.

Physiography, Climate and Soils The Lower Boreal Highlands Natural Subregion is 55,615km2, covering 15% of the Boreal Forest Natural Region (Natural Regions Committee 2006). The Lower Boreal Highlands Natural Subregion is the third largest subregion in Alberta and is the boreal analogue of the Lower Foothills Natural Subregion. It includes the lower slopes of the Cameron, Buffalo Head, Naylor and Clear Hills, Caribou and Birch Mountains, part of the Chinchaga Plain, and all the Stony Mountain and Peerless Uplands. It surrounds the higher elevation Upper Boreal Highlands and Boreal Subarctic Natural Subregions, and is bordered at lower elevations by the Central Mixedwood and Dry Mixedwood Natural Subregions. Elevations range between 400 m and 900 m in the Cameron Hills and Caribou Mountains, and between 700 m and 1000 m in the southern Clear Hills. This reflects a south-to-north decline of approximately 0.55 meters per kilometer for the upper boundary and a 0.82 m per kilometer decline for the lower boundary (Natural Regions Committee 2006). The Lower Boreal Highlands Natural Subregion includes the gently to strongly sloping lower elevations of the Northern Alberta Uplands, and also includes some undulating and hummocky upland areas. The underlying bedrock is a mixture of Cretaceous marine shales and sandstones. Medium textured glacial till on slopes and upland positions covers over 50 percent of the Natural Subregion, and shallow glaciolacustrine deposits occupy about 5 percent in toe slope and adjacent plain positions. Organic deposits, mainly in the broad Chinchaga valley, blanket about 30 percent of the area. Colluvium and residual materials occur in places on the steeper slopes, and there are scattered glaciofluvial deposits. Appendix 4 in Natural Regions of Alberta (2006) summarizes the proportional occurrence of landscape elements and parent materials in the Lower Boreal Highlands Natural Subregion. The Lower Boreal Highlands Natural Subregion is cooler and somewhat moister than the neighboring Dry Mixedwood and Central Mixedwood Natural Subregions. It has slightly warmer summers but much colder winters than its southern analogue, the Lower Foothills Natural Subregion. Growing degree-days are markedly fewer in the Lower Boreal Highlands Natural Subregion than in lower elevation neighboring Natural Subregions. This is probably a reflection of the dual influence of higher elevations and more northerly latitudes. Peak precipitation occurs in July, and monthly precipitation patterns are very similar to those of adjacent Natural Subregions. Figure 4-5.1 provides a comparison of temperature and precipitation patterns between boreal Natural Subregions, and Table 3-2 gives annual and seasonal climate statistics (Natural Regions Committee 2006). Orthic Gray Luvisols are the dominant upland soils; gleyed subgroups are common. Seepage is a locally common feature on lower slopes throughout much of the subregion, hence the extensive aspen-balsam poplar and mixedwood forests on lower slopes. Regosols occur on steep erosional slopes and on areas that are frequently disturbed such as riparian areas. Typic and Terric Mesisols are dominant organic soils in poor-to-rich fens. Fibric Mesisols and occasional Organic Cryosols are typical of bogs. Peaty Gleysols are common throughout the Natural Subregion (Natural Regions Committee 2006).

Approach and Methods of Classification Approach: Ecological classification hierarchy and terminology The system of classification in this guide was initially based on the community type approach of Mueggler (1988). Mueggler's system was chosen over the habitat type approach (Daubenmire 1952) or ecosystem association approach (Corns and Annas 1986) because it could classify plant communities irregardless of their successional status. However, as the philosophy of proper functioning condition of a site evolved, it became apparent (through data analysis) that there was a need to also organize the various plant communities based on their response to disturbance (i.e. disturbance vs. natural succession) within an area under similar environmental influences. It was determined that the ecosystem classification system developed by Corns and Annas (1986) and Beckingham et al. (1996) could accommodate this additional requirement. Thus, this classification system is a combination of Mueggler (1988) and Beckingham et al. (1996). Consequently, this guide adopts a similar ecological unit classification hierarchy (ecodistrict,ecosection, ecological site, ecological site phase, plant community). The ecological classification system is nested within Alberta's geographically based natural region and subregion classification system (Natural Regions Committee 2006). Ecodistrict
The ecodistrict level is a unique pattern of slope, landform, soils and vegetation. Mapping of this unit is usually done at a scale of 1:1,000,000 to 1: 250,000 within the whole province (Strong and Anderson 1980). This level of the classification hierarchy is spatially defined and may or may not be unique to a subregion. Ecosection The natural subregion used by the Alberta Government is equivalent to the ecoregion defined by the Canada Committee on Ecological Land Classification (CCELC) as part of a multi-level national mapping system for Canada and that was used for integrated resource planning in Alberta (Marshall et al. 1996). Similarly, the ecodistrict as presently used and its associated scale of mapping is equivalent to the ecodistrict defined by the CCELC. However, the ecosection has a somewhat different meaning in the current context than it did in the national system or than it did when it was applied to integrated planning maps in Alberta in the 1980's and 1990's. For those mapping projects, the ecosection was a subdivision of the ecodistrict and was mapped at 1:20 000 to 1:50 000 as a more specific delineation of recurring landform and vegetation patterns, usually with reference to major community type groups or soil subgroups. In the current scheme, the ecosection is a term used to define one ecodistrict or an aggregation of ecodistricts that represent one or more climatic variants within a natural subregion; therefore, its mapping scale is flexible. This level of the classification system is not spatially defined. The ecosection is a unique pattern of slope, landform, soils and vegetation and may also represent a slight change in the climate of a subregion. Mapping of this unit is usually done at a scale of 1:1,000,000 to 1:100,000 and can be a grouping of ecodistricts or at smaller scales outliers in a subregion. For example the Lower Boreal Highlands subregion is split into the foothills and boreal ecosections which are influenced by their proximity and location within the Boreal and Foothills Natural Regions. Spatially these two ecosections are split by grouping ecodistricts. In contrast an example of a smaller scale ecosection (1:100,000) is the Cypress Hills outlier of the Montane subregion. Subregion ecosections have a characteristic sequence of ecological sites according to soil moisture regime (SMR) and, to a lesser degree, soil nutrient regime (SNR).

Ecological Site Ecological sites are ecological units that develop under similar environmental influences (climate, moisture, nutrient regime). They are groups of one or more ecological site phases that occur within the same portion of the edatope (moisture/nutrient grid). Each ecological site is designated with a small letter. These letters range from "a" the driest ecological site and the last letter being the wettest. Each ecological site has been given a name that conveys some information about the ecology of the unit. Ecological sites are typically named after plant species that are common or typical of the site (eg. e low-bush cranberry). The plant that the ecological site is named after, however, may not be present in every plot or stand belonging to the site. Ecological site in this classification system, is a functional unit defined by moisture and nutrients. It is based on the combined interaction of biophysical factors which together dictate the availability of moisture and nutrients for plant growth. Thus, different ecological sites vary in their moisture and nutrient regime and that create recognizable differences in plant and soil development. Ecological site phase An ecological site phase is a subdivision of the ecological site based on the dominant species in the tree canopy. On lowland, meadow or grassland sites where tree canopy is not present the tallest structural vegetation layer with greater than 5% cover determines the ecological site phase. Generally, ecological site phases are mappable units and spatial ecological site phase land cover datasets have been developed from AVI (Alberta Vegetation Inventory) (Derived Ecosite Phase (DEP)) and PLVI (Primary Land Vegetation Inventory). Ecological site phases are identified by the ecological site letter "a" along with a number "a1" representing the phase within the ecological site. Ecological site phases have a distinct range in canopy composition and lower strata plant species. The ecological site phase has a strong ecological basis and correlates well with forest cover on forest inventory maps. Plant community type Ecological site phases may be subdivided into plant community types, which are the lowest taxonomic unit in the classification system. While plant community types of the same ecological site phase share vegetational similarities they differ in their understory species composition and abundance. Generally the plant community types are named by combining the name of the dominant plant species in each structural layer (eg. White spruce/Horsetail/Moss) Methods: Plant community classification Sampling for this guide occurred within the Lower Boreal Highland subregion. This guide outlines the classification of 482 plots described within the subregion. The procedure for inventory of plots followed the Ecological Land Survey Site Description Manual (2003) and uses various site, vegetation and soils forms. The data for each site was analysed using the multivariate analysis techniques of classification and ordination. Classification is the assignment of samples to classes or groups based on the similarity of species. A polythetic agglomerative approach was used to group the samples. This technique assigns each sample to a cluster which has a single measure. It then agglomerates these clusters into a hierarchy of larger and larger clusters until finally a single cluster contains all the samples (Gauch 1982). Cluster analysis was performed in SAS and Euclidean distance was used as the Cluster Distance Measure and Ward's method was used in the Group Linkage Method. The groupings generated in cluster analysis were overlain on the site ordination to determine final groupings. Ordination was used to find relationships among species, communities and environmental variables. Ordination reduces the dimensionality of the data to 1-3 most important axes to which environmental gradients can be assigned. The ordination technique used in the analysis of the data was DECORANA (Detrended Correspondence Analysis). DECORANA detrends and rescales the axes thereby reducing the arching and
4
compression of axes problems associated with other ordination techniques (Reciprocal averaging, Principle Components Analysis). Once final groupings were determined on the ordination specific environmental variables can be assigned to the variation outlined on the ordination axes. Plant community type summaries were generated by averaging plant species composition, range in composition, and percent constancy of occurrence, among vegetation inventory plots which were part of a community type. Environmental data was subsequently sorted into the same plant community groupings to create the plant community descriptions outlined in this guide. The number of sample plots on which the description was based is also provided (e.g. n=16). Ecological Health and Ecological Status Score Ecological health is determined by comparing the functioning of ecological processes on an area (e.g. plant community polygon) to a standard (i.e. Reference Plant Community) described within an ecological site description. An ecological site is defined by the Task Group on Unity and Concepts (1995) as, “a distinctive kind of land with specific physical characteristics that differs from other kinds of land in its ability to produce a distinctive kind and amount of vegetation”. This guide can be used to determine the appropriate reference plant community, within an ecological site, for a health assessment. We use health terminology (healthy, healthy with problems, or unhealthy), to rank the ability of the land to perform certain ecological functions. These functions include: net primary production, maintenance of soil/site stability, capture and beneficial release of water, nutrient and energy cycling and plant species functional diversity. For a detailed description on how to assess health for various plant communities please refer to “Rangeland Health Assessment for Grassland, Forest and Tame Pasture” (Adams et al. 2009). An ecological status score (i.e. the integrity of the plant community composition compared to the reference plant community) has been added to each community type description. These values are based on what is currently known about how a reference plant community (RPC) responds to various kinds and levels of disturbance or successional processes. The values indicate how a particular plant community fits in the state and transition model relative to the RPC. If an experienced observer wishes to estimate the health of a plant community without completing a health form, (e.g. a small riparian area), these values can be used as a guide. Occasionally there are 2 options provided for the ecological status score. This was done for two reasons: 1) to express the range of divergence from the RPC possible for a particular plant community; or 2) to allow for different health forms to be used in communities with variable shrub or tree cover (e.g. on sites with high woody cover and/or an obvious LFH layer use the forest rangeland health form and the corresponding ecological status score; on sites dominated by herbaceous cover and/or an obvious herbaceous litter layer use the native grassland form). Late seral plant communities tend to be superior in the efficient capture of solar energy, in cycling of organic matter and nutrients, in retaining moisture, in supporting wildlife habitat values and in providing the highest potential productivity for the site. In contrast, early seral disturbed stages represent plant communities with diminished ecological processes, which are less stable and more vulnerable to erosion and invasion by weeds and non-native species. In most cases these late seral plant communities are used as the RPC, but sometimes management goals influence the choice of RPC (e.g. a cut block to be maintained as untimbered rangeland).

Correlation of Soils and Ecological Sites Typical soils are moderately fine textured Gray Luvisols and gleyed subgroups. Reference sites of average moisture and nutrients are variable and may be pure or mixed stands of aspen, white spruce, white birch, hybrid pine or black spruce (Natural Regions Committee 2006). White spruce–feather moss communities develop if stand-replacing fires do not occur for a sufficiently long period. These communities are relatively common in the Lower Boreal Highlands Natural Subregion; balsam fir is a common associate at higher elevations and represent the mesic/medium ecological site. On nutrient-poor sites, lodgepole pine–jack pine hybrids form stands with black spruce; understories include common Labrador tea, bog cranberry and feathermosses and represent the mesic/poor ecological site. On the wetter sites, black spruce is typically the leading species, and white spruce may also occur where nutrient conditions are somewhat better. Soils are moderately well to poorly drained, variable textured Luvisols and gleyed subgroups, Brunisols and Gleysols (Natural Regions Committee 2006). On moist, rich sites, balsam poplar, aspen and white spruce occur as pure or mixed stands with understories of red-osier dogwood, bracted honeysuckle, prickly rose and bluejoint and represent subhygric/rich ecological sites. Soil textures are variable, and soils are Luvisols or Gleysols. Wetlands include nutrient-poor black spruce fens with common Labrador tea, peat mosses and feathermosses. Tamarack–black spruce stands or willow–dwarf birch shrublands with sedges, bluejoint, golden moss and other rich-site vascular and non-vascular associates occur in wetlands receiving nutrient-rich waters. Organic soils are dominant and Gleysols are common (Natural Regions Committee 2006).

Guidelines for Determining Ecological Sites Alberta currently uses two ecological classification methods to determine ecological sites. In the agricultural settlement area of the Province, resource managers can determine site soil conditions using AGRASID (Agricultural Region of Alberta Soil Inventory Database). In the Rocky Mountain, Foothills and Boreal Natural Regions, the Ecological Landscape Classification approach incorporates both vegetation and site conditions (climate, soils and geology) into a hierarchical ecological unit classification (e.g. subregion, ecodistrict, ecosection, ecological site, ecological site phase, plant community) (Strong and Thompson 1995). Ecological sites are areas of similar climate, moisture and nutrient regimes. The combination of moisture and nutrient regimes can be represented on a two-dimensional grid called the edatope grid. The edatope grid is a two-dimensional table with soil moisture regime on one axis and soil nutrient regime on the other. Soil moisture regime (SMR) is defined as the average amount of soil water available annually for evapotranspiration by vascular plants (Meidinger and Pojar 1991). The SMR uses nine classes to define the available soil moisture, which range from the driest (very xeric) to the wettest (hydric). Soil nutrient regime (SNR) is defined as the amount of essential soil nutrients that are available to vascular plants over a period of several years (Meidinger and Pojar 1991). SNR is broken down into five classes that range from A (very poor) to E (very rich). Generally ecological sites are named from low moisture/low nutrient to high moisture/high nutrient. The unique combination of moisture and nutrients creates conditions for a particular ecological site within a subregion. For example a subxeric, poor nutrient regime site is characterized by the "a" [bearberry (subxeric/poor)] ecological site. A resource manager can review the indicator plant species of the ecological site, plant community types, soils and site conditions to see if the plant community in question fits the general descriptions. The following steps provide a framework for determining ecological sites. Step 1 Review background information and pre-stratify the area to be classified Review information about the area you are investigating to learn what you can about the landscape and ecology. Consult the natural subregions and Derived Ecosite Phase (DEP) or Primary Land Vegetation Inventory (PLVI) maps to ensure you are using the correct subregion guide. DEP and PLVI classification will also give you the common ecological site phase for a particular forest polygon. Step 2 Carry out a quick reconnaissance of the site to be classified Take note of the variability and relationship between topography and position on the landscape and the general plant species distribution including trees and understory. Check the DEP and PLVI ecological site phase maps. Step 3 Choose a location that appears to be representative of the area to be classified Locate an area for your assessment that appears to be representative of the site to be classified, and is homogeneous in slope, plant cover, and overstory canopy conditions as possible. Avoid locating the sample in areas that have received significant natural or artificial disturbance. Also avoid ecotone areas or relatively small areas that are transitional between homogenous ecological units such as slope breaks. Step 4 Determine the plant species composition and abundance Determine the plant species composition and abundance within a 10x10 m plot. Also record any species that appear to be representative of the ecological unit but occur outside the plot within the same slope position and on the same parent materials. Abundance is estimated by determining the amount of ground area that is covered by the plant species when its canopy is projected onto the ground surface. Step 5 Determine the important soil properties To collect soils data, a soil pit must be dug or augered. In most cases a soil pit 60 cm deep will be adequate. A deeper pit is required when the soil has a coarse to moderately coarse texture. In these cases the pit is dug
7
deeper to see if there are finer-textured layers that are influencing ecological function below the 60 cm of coarse material. A deeper pit is also required when the plant community on the site cannot be explained by the site conditions and soil conditions above 60 cm. The minimum soils data that should be collected within a plot to classify it correctly are organic matter thickness, humus form, Ah horizon thickness, surface texture, effective texture, presence of seepage, depth to mottles, depth to gley, coarse fragment content, parent material/landform and drainage. Step 6 Determine important site properties Important site variables that should be collected include topographic position, slope, aspect, moisture regime, and nutrient regime. Step 7 Determine the natural subregion, ecological site, ecological site phase and plant community type. There are several ways to determine the ecological site, ecological site phase and plant community type. The first way is to assign an ecological classification to a site is to use the field data collected and go through the various subregion guides to identify the ecological site. You can also use the dichotomous keys to ecological site and ecological site phase. Once you find a potentially correct plant community type, check the soil, site and vegetational characteristics of your site to make sure it matches the ecological site, ecological site phase and plant community type on the various fact sheets. To consider all ecological site choices, you must compare the characteristics of your site, with the descriptions on the fact sheets for all ellipses that overlap the moisture and nutrient classes of your site on the edatope grid for the subregion and adjacent subregions within the area.

How to use the Guide Organization of the guide This guide is an expansion of the Ecosites of Northern Alberta guide (Beckingham and Archibald 1996). It contains new information and it is recommended that the reader has access to relevant information from both guides. The community types in this guide are closely related to the ecosites and ecosite phases outlined in Ecosites of Northern Alberta (Beckingham and Archibald 1996), and are similarly arranged (e.g. Table 1 and 2). Table 1 and 2 is a reproduction of Figure 14 in Ecosites of Northern Alberta with community types in this guide further separated into reference range plant communities, successional communities and harvesting and fire communities. The "Successional community types" or "Harvesting and Fire succession" categories outline the successional sequence the community types undergo with heavy grazing pressure, harvesting or fire disturbance. The bulk of this guide is community descriptions which include information on the dominant plant species, canopy cover, environmental conditions. When available, we have included plant community successional (ie response to grazing) information to help us determine rangeland health and the successional relationships on an ecological site. Generally ecological units within this subregion are classified by "ecosection (foothills, boreal)" and then their position on the edatopic grid [a specific combination of soil moisture and soil nutrient regime] . The information in this guide is presented and named by: 1. Subregion/Ecological area a. Lower Boreal Highlands [LBH] 2. Ecosection (foothills/boreal) a. Foothills (LBHf) b. Boreal (LBHb) 3. Dominant cover type a. A-grassland b. B-shrubland c. C-deciduous d. D-mixedwood e. E-conifer 4. A number- Generally, communities are named/numbered from low moisture /nutrient status to high moisture/nutrient status. For example, LBHfE1 Pl/Rose/Hairy wildrye community on the"b" submesic/medium ecological site, while LBHfE15 Sb-Lt/Peat moss community type on the "i" subhydric/medium ecological site. Eg. LBHfE1 Pl/Rose/Hairy wildrye NOTE: As additional information is collected and new ecological units are identified and described, an attempt is made to fit them into the pre-existing ones. How to read the fact sheets The field guide contains 4 types of fact sheets: One for ecosection, one for ecological site, one for ecological site phase and one for plant community type. Ecosection There is an identification code at the top of the ecosection fact sheet and a name followed by the number of sample sites (pg 26). Each ecosection has been given a name that conveys information about the location of
9
the unit and are frequently named after a general location within the subregion (Ecosection: Cypress Hills (Mc) of the Montane subregion). A short text description of the site is given under the General Description (pg 26), this is followed by a picture or a cross section diagram and map of the ecosection (pg 26). The section on successional relationships gives a brief note about the spatial locations and differences in ecosections (pg 26). This is followed by a list of envrionmental variables (elevation), ecodistricts and ecological sites associated with the ecosection (pg 26). Ecological site There is an identification letter at the top of the ecological site fact sheet and a name, moisture and nutrients followed by the number of sample sites (pg 27). Each ecological site has been given a name that conveys information about the ecology of the unit and are frequently named after a common plant species. A short text description of the site is given under the General Description (pg 27), this is followed by a picture or a cross section diagram of the ecological site (pg 27). The section on successional relationships gives a brief note about the temporal development of the ecological site (pg 27). It generally describes the successional relationships among the ecological site phases and plant community types. Plant species that are indicators of the ecological conditions on the site are listed (pg 27). Site index at 50 years of age at breast height (1.3 m) is presented next. The mean site index is presented in meters followed by the standard error and the number of trees used to calculate the mean (pg 27). Environment and soil variables are then listed and represent a roll-up from the plant community and ecological site phase descriptions (pg 27). Variables that represent environment and soils have a number (1) that indicates the number of the samples in which each variable class occurred. Data has been collected and analyzed from many sources over 40 years and data gaps may exist for many variables. The frequency of occurrence value indicates the number of sampled plots for which data was collected for that variable at the Ecological site, Ecological site phase and plant community fact sheets. Optional variables such as soil exposure, LFH thickness, forage production and stocking rate for livestock may also be listed and represent a roll-up for the plant community and ecological site phase. Ecological site phase There is an identification code at the top of the ecological site phase fact sheet and a name followed by the number of sample sites (pg 28). Each ecological site phase has been given a name that conveys information about the dominant tree species or lifeform (shrubland, grassland, tame/disturbance) of the unit and are frequently named after a common plant species. A short text description of the site and successional information maybe given under the General Description or Successional relationships (pg 28) if it is provides more detail than is available on the ecological site fact sheet. Plant species that are indicators of the ecological conditions on the site are listed with the average cover summarized from the various plant communities (pg 28). Indicator species for the ecological site phase are identified with an asterix "*" and are rolled-up to develop the indicator species list for the ecological site fact sheet. Environment and soil variables are then listed and represent a roll-up from the plant community (pg 28). Optional variables such as soil exposure, LFH thickness, forage production and stocking rate for livestock may also be listed and represent a roll-up for the plant communities. Plant community There is an identification code at the top of the plant community fact sheet and a name followed by the number of sample sites (pg 29). The name of the plant community is generally the common name of the indicator plant species within the various lifeform layers (tree, shrub, forb, grass, lichen, moss). This is followed by the latin name of each indicator species and a general description of the community type describing its unique ecology. Plant species that are indicators of the ecological conditions on the site are listed with the mean cover summarized, range in cover and overall constancy (frequency of plots that the species was described (pg 29). Environment and soil variables are then listed and represent a roll-up from the various plots and assessements (pg 29). Optional variables such as soil exposure, LFH thickness, forage production and stocking rate for livestock may also be listed and represent a roll-up for various plots.

General Ecological Descriptions Forested community types The Lower Boreal Highlands Natural Subregion is the major zone of hybridization between lodgepole pine and jack pine and this is typically true within the boreal ecosection. Plot data from the foothills ecosection indicates that jack pine is less common in the northwestern areas of this subregion. The foothills ecosection is dominated by lodgepole pine forests and has little presence of jack pine. The hairy wildrye ecosite is also found within the foothills ecosection, but was not described within the boreal ecosection. The hairy wildrye ecosite is described in both the Upper and Lower Foothills subregions (Beckingham et al. 1996). Bearberry, lichen, common Labrador tea and common blueberry occur on the driest sites. Lodgepole pine-jack pine hybrids grow in pure or mixed stands with aspen and white birch, green alder, common Labrador tea, common blueberry and bog cranberry on well drained, coarse textured substrates (Natural Regions Committee 2006). Modal community types on sites of average moisture and nutrient status in the Lower Boreal Highlands are variable and may be pure of mixed stands of aspen, white spruce, white birch, hybrid pine, and black spruce. White birch, balsam poplar, white spruce and hybrid pine tend to replace aspen as the dominant tree species in pure or mixed stands, at higher elevations and where seepage occurs. Pure white birch stands are a distinctive feature at upper elevations in the Lower Boreal Highlands (Natural Regions Committee 2006). Understory species include rose, Canada buffaloberry, hairy wild rye, bluejoint, bunchberry, wild sarsaparilla, dewberry and feather mosses; species diversity likely decreases to the north. White spruce-feather moss communities develop if stand-replacing fires do not occur for a sufficiently long period. These communities are relatively common in Lower Boreal Highlands; balsam fir is a common associate at higher elevations. On nutrient-poor sites, lodgepole pine-jack pine hybrids form stands with black spruce; understories include common Labrador tea, bog cranberry, and feather mosses. On the wetter sites, black spruce is typically the leading species, and white spruce may also occur where nutrient conditions are somewhat better (Natural Regions Committee 2006). On moist, rich sites, balsam poplar, aspen and white spruce occur as pure or mixed stands with understories of red-osier dogwood, bracted honeysuckle, prickly rose, bluejoint and other herbs in deciduous and mixedwood stands, or a carpet of feather mosses and horsetails in coniferous stands. Tall willow communities with similar understories may also occur. These sites are typically found in association with seepage zones along streams. Bluejoint may establish tall monocultues if the overstory is removed by fire or harvest. Wetlands The Alberta Wetland Classification System (2015) recognizes the hydrological, biogeochemical and biotic processes that affect differing characteristics that can be used to define a wetland. The AWCS recognizes five classes of wetlands in Alberta: bogs, fens, marshes, shallow open water and swamps. Wetlands can be divided into two broad groups: peatlands and mineral wetlands. In general the AWCS considers bogs and fens to be peatlands and all other wetland classes (i.e. swamps, marshes and shallow open waters) are considered to be mineral wetlands. For the most part the ecological sites align with AWCS five classes of wetlands (Table A), however some sedge, marsh reedgrass and tufted hairgrass dominated ecological sites because of their moisture regime and species composition are classified as meadows or fens but are mineral wetlands which are considered marshes or swamps in the AWCS classification system.

Marsh Marsh Swamp Red osier dogwood, Honeysuckle, Horsetail and wetter Labrador tea, black spruce dominated ecological sites There is little open water in the Lower Boreal Highlands Natural Subregion other than a few small lakes in the Buffalo Head Hills, Peerless Upland and Birch Mountains. The Chinchaga and Birch Rivers are the largest watercourses. The total area covered by water is about 1 percent of the total land area in this Natural Subregion(Natural Regions Committee 2006) . Wetlands occur across about 35 percent of the area on average, but local percentages range from 20 to 60 percent. Wetlands are mainly treed and shrubby fens, except on the Chinchaga Plain to the north of the Clear Hills where bogs make up about 50 percent of the wetland area. Wet mineral soils occupy about 5 to 10 percent of the total area. Wetlands include nutrient-poor black spruce fens with common Labrador tea, peat mosses and feather mosses. Tamarack-black spruce stands or willow-dwarf birch shrublands with sedges, bluejoint, golden moss and other rich-site vascular and non-vascular associates occur in wetlands receiving nutrient-rich waters (Natural Regions Committee 2006). Shrublands Upland sites forest sites disturbed by fire will often have a early successional shrub phase. Labrador tea, lichen and feather moss tend to dominate the poorer sites and rose, Saskatoon and Bebb's willow the more mesic sites. Shrub communities dominated by willow, water birch and bog birch dominate the moister and richer sites. Sedges and reed grasses (Calamagrostis spp) dominate the drier edges of marshes or areas that have standing water only during spring runoff (i.e. fens). Willow will invade into these fens to form the Willow/Sedge and Willow/Reed grass plant communities and bog birch and Labrador tea tend to dominate the poorer nutrient sites.

LBHb Boreal Ecosection (n=227) Natural Subregion: Lower Boreal Highlands General Description This ecosection is defined by ecodistricts that are influenced by a boreal climate and boreal physiography. These ecodistricts include: Cameron Slope, Cameron Hills Upland, Caribou Slope, Caribou Upland, North Birch Upland, Birch Upland, Peerless Upland, Stony Mtn. Upland, Crow Lake Plain, Buffalo Head Upland, Wadlin Upland and Russell Upland.
Successional Relationships The boreal ecosection is the major zone of hybridization for jack pine and lodgepole pine and both species are present. In contrast the foothills ecosection is dominated by lodgepole pine forests and has little presence of jack pine. The hairy wildrye ecosite is also found within the foothills ecosection, but was not described within the boreal ecosection. The hairy wildrye ecosite is described in both the Upper and Lower Foothills subregions (Beckingham et al. 1996).

a bearberry/lichen (subxeric/poor) (n=2) Natural Subregion: Lower Boreal Highlands Ecosection: LBHb Boreal
General Description This ecosite has dry conditions with rapidly drained acidic soils and poor nutrient status due to the coarse-textured fluvial or eolian parent materials. Plants that are indicative of the nutrient-poor substrate include bearberry, lichen, bog cranberry, and blueberry. Open-canopied jack pine stands dominate this ecosite that commonly has a carpet of lichens covering the forest floor. This ecological site is not common in the Lower Boreal Highlands as the majority of the subregion is dominated by medium textured glacial till deposits on slopes of the northern hill systems.
Successional Relationships Due to the dry nature of this ecosite, succession to a black spruce canopy is slower than the fire return interval. Pine is maintained for relatively long periods from colonization of the site after fire to the climax stages. The pine phase of this ecosite can be considered a fire edaphic climax.

LBHbE1 Pj/Bearberry (n=2) (Pinus banksiana/Arctostaphylos uva-ursi) The understory of this community type is dominated by bearberry, lichen and bog cranberry. This community type occupies very dry sandy sites that are rapidly drained. Succession in the absence of disturbance will be to black spruce, but this succession is slower than the fire return interval. These pine dominated communities can be considered a fire edaphic climax. Allen and Johnson (2007) described a similar community dominated by jack pine and bog cranberry on a number of sites in the Birch Hills.

b blueberry(submesic/medium) (n=19) Natural Subregion: Lower Boreal Highlands Ecosection: LBHb Boreal
General Description This ecosite tends to be subxeric to submesic partly due to coarse-textured parent materials. It is intermediate in both moisture and nutrient regime between the bearberry ecosite (a) and the buffaloberry/alder ecosite (d). As such it has species characteristic of the bearberry ecosite such as jack pine, blueberry, bearberry, bog cranberry, Labrador tea, and reindeer lichen and also species characteristic of the buffaloberry ecosite such as aspen, buffaloberry, bunchberry, alder, and fireweed. Allen and Johnson (2007) felt this ecological site was common in the Lower Boreal Highland subregion but was only described from a few sandy terraces adjacent to a number of lakes in the Birch Hills.
Successional Relationships The pine, aspen, and white birch-dominated phases of this ecosite may, in some cases, succeed to white spruce, however the process is expected to be relatively slow due to the dry nature of these sites.

LBHbD1 Pj-Aw/Blueberry (n=2) (Pinus banksiana-Populus tremuloides/Vaccinium myrtilloides) This community type is the modal plant community for this ecological site. This community is very similar to the jack pine/blueberry dominated communities but appears to be slightly moister. The understory of this community type is dominated by blueberry and there is an increase in cover of more mesic plant species like alder, rose, bedstraw and wild lily of the valley. However despite the increase in moisture this community type still occupies coarse textured sites that are rapidly drained.

c Labrador tea-mesic(mesic/poor) (n=43) Natural Subregion: Lower Boreal Highlands Ecosection: LBHb Boreal
General Description This ecosite has a subxeric to subhygric nutrient-poor substrate. Labrador tea and bog cranberry are indicative of the relatively acidic surface soil conditions. It occurs in upland (midslope and upper slope) or level topographic positions dominantly on till or fluvial over till parent materials. There is commonly a two-tiered even-aged canopy where the faster growing jack pine comprise the higher layer and the slower growing black spruce form a secondary canopy below the pine. While the Labrador tea-mesic ecosite (c) has plant community types similar to the Labrador tea-subhygric ecosite (g), the mesic ecosite tends to occur in upper topographic positions, has no mottles within the top 25 cm of soil, and a thinner organic layer.
Successional Relationships Successionally mature stands that develop on these ecosites may be dominated by black spruce. Residual pine occurring in the climax community are generally very old. The successionally mature stage is rare due to high fire frequency.

LBHbD2 Aw-Sb/Moss (n=4) (Populus tremuloides-Picea mariana/Pleurozium schreberi) This community type occupies the moister end of the spectrum with a slightly richer nutrient regime within the Labrador tea-mesic ecological site. Successionally mature sites are often dominated by black spruce within this ecological site. The presence of a high cover of aspen and willos indicate the slightly better nutrients. This community type is well to moderately well drained and has a coarser soil texture. In the absence of disturbance this community type will likely succeed to a black spruce dominated community.

LBHbB1 Alder-Labrador tea (Pl-Pj) (n=2) (Alnus crispa-Ledum groenlandicum(Pinus contorta-Pinus banksiana)) This community type is successionally immature and represents burned sites that are regenerating lodgepole and jack pine. This community has a mesic moisture regime and a poorer nutrient regime than the reference community types found on mesic sites with medium nutrients. In the continued absence of disturbance this community will likely succeed to a mixed white and black spruce dominated community type.

d low bush cranberry (mesic/medium) (n=127) Natural Subregion: Lower Boreal Highlands Ecosection: LBHb Boreal
General Description This is the reference ecosite for the Lower Boreal Highland subregion because of the mesic moisture regime and a medium nutrient regime. Generally, these ecosites have fine to medium textured glacial till with Gray Luvisols and gleyed subgroups. Generally these sites are dominated by pure or mixed stands of aspen, white spruce, white birch, hybrid pine or black spruce. At higher elevations white birch, white spruce and hybrid pine tend to replace aspen in pure or mixed stands (Natural Regions Committee 2006). Understory species include rose, green alder and buffaloberry and have a high diversity of forbs (wild sarsaparilla, dewberry, bunchberry) and grasses (bluejoint, hairy wildrye) in the understory.
Successional Relationships Pioneer species such as aspen and white birch are replaced by white spruce. Pine stands maybe dominated by pure lodgepole pine or pure jack pine and the full range of hybrids. White spruce and balsam fir communities develop if stand replacing fires do not occur over longer periods of time (Natural Regions Committee 2006).

LBHbD3 Aw-Sw/Rose/Hairy wildrye (n=6) (Populus tremuloides-Picea glauca/Rosa acicularis/Elymus innovatus) This community type is very similar to the hairy wildrye dominated community types described in the foothills ecosection. Indeed, the majority of plots in this community type were described near Haig Lake in the Buffalo Head Hills which is found on the western edge of the boreal ecosection. This community is considered successionally immature. The high cover of hairy wildrye in this community type indicates slightly drier site conditions than the modal conditions for this ecological site. In the Lower Foothills subregion hairy wildrye is indicative of submesic sites with medium nutrient regimes. In the continued absence of disturbance this community will succeed to a Sw/Moss dominated community type and then balsam fir, but the process maybe slow due to the drier nature of this plant community type.

LBHbD4 Aw-Sw/Low bush cranberry/Moss (n=8) (Populus tremuloides-Picea glauca/Viburnum edule/Pleurozium schreberi) This community is considered successionally immature. In the absence of disturbance spruce will eventually dominate the community to form the Sw/Moss dominated community type. In the continued absence of disturbance this community will eventually succeed to a White spruce/Balsam fir dominated community type.

LBHbC2 Aw/Rose-Low bush cranberry (n=28) (Populus tremuloides/Rosa acicularis-Viburnum edule) This plant community appears to be the modal aspen community type under limited disturbance on mesic, medium to rich sites. The presence of tall forbs such as fireweed, and peavine distinguish this community from the low forb type described in the Central Mixedwood subregion. It has also been observed that the low forb type can be produced when the tall forb community is lightly to moderately grazed for a number of years (Willoughby 1996). If the canopy is relatively open, marsh reed grass is abundant.

LBHbC3 Aw/Buffaloberry (n=11) (Populus tremuloides/Shepherdia canadensis) This community type was found on mesic sites, with shallow slopes and had medium nutrient regimes. Beckingham (1993) felt the Aw/Buffaloberry type was slightly drier and had a slightly poorer nutrient regime than the more modal Aw/Alder or Aw/Low bush cranberry dominated community types. A similar buffaloberry dominated community was described at upper elevations in the Birch and Saddle Hills of the Boreal Mixedwood Natural Region (Moisey et al. 2012).

LBHbC7 Bw-Aw/Low bush cranberry-Rose (n=15) (Betula papyrifera-Populus tremuloides/Viburnum edule-Rosa acicularis) This plant community is similar to other aspen dominated community types in the low-bush cranberry ecological site, but is dominated by paper birch rather than aspen. This type has vegetative affinities with the Aw/Rose-Low Bush Cranberry type due to the common mesic substrate characteristics, but the birch type appears to be slightly more acidic and with slightly poorer nutrients.

LBHbE5 Pl/Moss (n=3) (Pinus contorta/Stair step moss) In the Lower Boreal Highlands subregion pine stands maybe dominated by pure lodgepole pine, pure jackpine or a full range of hybrids. On drier sites the understory will be dominated by bearberry, lichen or blueberry. On more mesic sites the understory is dominated by feather mosses, bunchberry and fireweed. This community type is ecologically similar to the Sw/Moss community but is successionally less advanced. As this forest grows older, white spruce will eventually replace lodgepole pine as the dominant tree species. This community type represents an intermediate state between a young seral deciduous stand and a climax white spruce - balsam fir stand.

e red osier dogwood (subhygric/rich) (n=4) Natural Subregion: Lower Boreal Highlands Ecosection: LBHb Boreal
General Description The dogwood ecosite is subhygric and nutrient rich. These sites are commonly found on level or depressional areas near the base of slopes or near watercourses that receive nutrient rich seepage or are occassionally flooded. Fine textured till and lacustrine parent materials are common.
Successional Relationships Succession to conifer on these rich sites proceeds slowly because of the proliferation of grass, forbs and shrubs after disturbance. These sites are often dominated by balsam poplar and red osier dogwood with the succession to spruce in the absence of disturbance.

LBHbD6 Pl-Pb/Alder (n=1) (Pinus contorta-Populus balsamifera/Alnus crispa) This reference plant community represents a mixedwood phase of the red osier dogwood ecological in the Lower Boreal Highlands subregion. Succession in the absence of disturbance will be to lodgepole pine and eventually a white spruce dominated community type. The presence of balsam poplar indicates the slightly better nutrient status and higher moisture content of this community type than the Aw-Sw/Alder and Aw/Alder dominated community types.

LBHbC5 Aw/Willow (n=1) (Populus tremuloides/Salix scouleriana) This community type was described on a westerly facing slope and appears to occupy areas that receive some nutrient seepage throughout the growing season. There are some trees growing on these sites, but they are generally restricted to the drier areas. This community is similar to the Willow-Alder/fern community that was described on nutrient rich seepage areas in the Saddle Hills northwest of Grande Prairie in the Lower Foothills subregion. This community type is very productive, but it is difficult to graze because of the slope and the high cover of alder and willow which restricts livestock movement. This community type should be rated as non-use.

LBHbB2 Shining willow-Red fruited bearberry/Moss (n=1) (Salix lucida-Arctostaphylos rubra/Brachythecium salebrosum) This community appears to be an early successional community near riparian areas which periodically flooded or has water close to the surface. Red fruit bearberry pioneers on gravel floodplains and other bare substrates in primary succession. It colonizes bare mineral soil in tundra and taiga sites in Alaska (Densmore 1979 http://www.fs.fed.us/database/feis/plants/shrub/arcrub/all.html#13) and can persist in the understory in mature spruce and pine stands. Shining willow is another pioneer species found growing on lake and slough margins, river floodplains and sand dune slacks (Moss 1994). In the absence of disturbance this community will likely succeed to a white spruce dominated community type.

f horsetail (hygric/rich) (n=10) Natural Subregion: Lower Boreal Highlands Ecosection: LBHb Boreal
General Description The horsetail ecosite is wet and nutrient rich. These sites are commonly found on till, lacustro-till and fluvial parent materials where flooding or seepage enhances the substrate nutrient supply (Beckingham and Archibald 1996). The high water tables, wet soil conditions and Gleysolic soils tends to lead to the accumulation of organic matter. Horsetails often dominate the forest floor and these sites are often associated with running water.
Successional Relationships Succession on these sites is largely controlled by high soil water content. Some sites that have peaty soils may have taken hundreds of years to develop (Beckingham and Archibald 1996). When the trees are removed the water table may rise making tree establishment difficult. These sites are often dominated by White spruce in the last successional stage.

LBHbE10 Sw/Horsetail (n=8) (Picea glauca/Equisetum arvense) This community type is moist and nutrient rich. These sites are commonly found on fluvial or glaciolacustrine parent materials where flooding or seepage enhances the substrate nutrient supply. With high water tables and moist soil conditions, organic matter tends to accumulate which favors the growth of horsetails. Horsetail communities often are dominated by white spruce because the higher moisture conditions limit the fire return interval.

g labrador tea-horsetail (hygric/medium) (n=2) Natural Subregion: Lower Boreal Highlands Ecosection: LBHb Boreal
General Description The Labrador tea-subhygric ecosite has a nutrient-poor substrate with imperfectly to very poorly drained soils. Labrador tea and bog cranberry are indicative of the relatively acidic surface soil conditions. It dominanly occurs on fine-textured till or glaciolacustrine deposits, on coarse- textured glaciofluvial material, where the wet soil conditions promote the development of Gleysolic soils. While the Labrador tea-hygric ecosite has plant community types similar to the Labrador tea-mesic ecosite, the hygric ecosite tends to occur in lower topographic positions, has mottles in the top 25 cm of soil, has a thicker organic layer, and may be dominated by black spruce rather than pine. High soil water content associated with this ecosite creates a greater risk of site modification if operations occur within months when the soil is not frozen (Beckingham and Archibald 1996).
Successional Relationships Young and mature stands developing in this ecosite often have a component of black spruce. The black spruce is often the same age as the pine but forms a secondary canopy due to slower growth rates. Successionally mature stands are dominated by black spruce with a small component of residual pine (Beckingham and Archibald 1996).

h bog (subhydric/very poor) (n=10) Natural Subregion: Lower Boreal Highlands Ecosection: LBHb Boreal
General Description Wetland types in the boreal ecosection of the Lower Boreal Highlands subregion are generally dominated by treed and shrub fens (Natural Regions Committee 2006). Bog ecosites are less common and have a very poor to poor nutrient regime and are poor to very poorly drained. Organic soils consisting of slowly decomposing peat moss are common. This ecosite occupies level and depressional areas where water tends to be stagnant and impeded drainage or high water tables enhance the accumulation of organic matter. Stunted black spruce forms a sparse canopy on the treed phase (h1) of the bog ecosite. Leatherleaf (Chamaedaphne calyculata) is very common in the bog ecosite.
Successional Relationships The bog ecosite is an edaphic climax that is maintained by water tables. The hydrarch succession that leads to the bog ecosite is extremely slow.

LBHbB4 Labrador tea/Peat moss (Sb) (n=4) (Ledum groenlandicum/Sphagnum spp.(Picea mariana)) This community type is typical of a shrub bog ecological site phase. Fire disturbance kills the overstory trees and allows shrubs to dominate the community type. Rich fens tend to be dominated by larch, willow and golden moss, whereas, bogs are dominated by black spruce, Labrador tea and peat moss. In the absence of disturbance (ie fire) this community will eventually become dominated by black spruce.

General Description This ecological site phase currently has no data and graminoid bogs have not been described in the Boreal Natural Region. This ecological site phase was created for photo interpretation of vegetation for Alberta Vegetation Inventory (AVI) and Primary Land Vegetation Inventory (PLVI) if the interpreters call for a mapcode of 9B (Hydric/very poor). If interpreted in the various vegetation land cover inventories it will provide a spatial location in which to sample.

i poor fen (subhydric/medium) (n=2) Natural Subregion: Lower Boreal Highlands Ecosection: LBHb Boreal
General Description The poor fen ecosite is intermediate in nutrient regime between the bog (h) and the rich fen (j) ecosites and as such has species characteristic of both. Drainage is poor to very poor, however, there is some movement of water through the substratum. This ecosite occupies level and depressional areas where impeded drainage or high water tables enhance the accumulation of organic matter. This organic matter consists of a combination of bog-type organic matter (peat moss) and rich fen-type organic matter (sedges, golden moss, tufted moss, and brown moss). Both the black spruce and/or tamarack that dominate a sparse canopy on the treed phase (i1) of the poor fen ecosite are stunted and generally considered unmerchantable (Beckingham and Archibald 1996).
Successional Relationships The hydrarch succession characteristic of this ecosite occurs over periods of hundreds to thousands of years. Thus, recovery from disturbance is extremely slow. Changing hydrologic regimes that can result from disturbance influence the direction and rate of succession. As these systems depend on water flow through them, impeding this flow can result in reduction or elimination of tree cover and changes in the shrub, forb and grass layers(Beckingham and Archibald 1996).

LBHbB5 Sb/Willow/Northern bog sedge/Golden moss (n=1) (Picea mariana/Salix myrtillifolia/Carex gynocrates/Tomenthypnum nitens) This ecosite is intermediate between a bog and rich fen. LBHbB5 is a shrubby phase poor fen, distinguishable from a bog by having significant cover of species usually associated with a rich fen (e.g. willows, sedges, and golden moss). It also has plants usually associated with bog communities (e.g. black spruce, labrador tea, Northern bog sedge). If conditions are favorable for tree growth, black spruce and larch will become prominent changing the plant community to a treed poor fen.

LBHbB3 Bog willow/Lesser panicled sedge-Mud sedge (n=1) (Salix pedicellaris/Carex diandra-Carex limosa) This community represents very wet boggy areas because they receive some nutrient rich seepage throughout the growing season. Allen and Johnson (2007) described both Lesser panicled sedge and mud sedge dominated communities adjacent to thermokarst pools and collapse scars in the Birch Mountains. They found these communities wetter than the surrounding bogs but they were not under water.

j rich fen (subhydric/rich) (n=8) Natural Subregion: Lower Boreal Highlands Ecosection: LBHb Boreal
General Description The rich fen ecosite is characterized by flowing water and alkaline nutrient-rich conditions. The soil is composed of organic matter derived from decomposing sedges, as well as golden, tufted, and brown mosses. This ecosite occupies level and depressional areas where the water table is at or near the surface for a portion of the growing season. Tamarack dominates the canopy on the treed phase while dwarf birch or willow form the canopy of the shrubby phase, and sedges dominate the graminoid phase of the rich fen ecosite.
Successional Relationships The rich fen is an early stage in hydrarch succession. Species composition, and direction and rate of succession changes with the changing hydrologic regime. As with other wetlands, rich fens have slow successional rates, so recovery from disturbance may also be slow.

LBHbB6 Willow/Marsh reedgrass (n=2) (Salix spp./Calamagrostis canadensis) This plant community was found along the edges of reed grass or sedge fens (meadows) and in moist depressions. Willow will invade onto these graminoid fens to form the Willow/Reed grass community type as the site drys. Increased grazing pressure on these sites will cause marsh reed grass to decline and there will be an invasion of Kentucky bluegrass and dandelion. Increased flooding and prolonged waterlogging may result in the disappearance of willow and a transition to a graminoid fen.

LBHbA2 Kentucky bluegrass/Dandelion (n=2) (Poa pratensis/Taraxacum officinale) This community type was described on a grazing disposition just north of Hines Creek within the Whitemud hills. This Plant Community represents a reed grass fen (LBHbA2) that has been moderately to heavily grazed resulting in disturbance and/or invasive species displacing native species. The disturbance species actually present may vary depending on local propagules, but Kentucky bluegrass, nettles and other weedy forbs are commonly found. It is a fairly productive community type but grazing should be timed to avoid wet soil conditions.

k marsh (hydric/rich) (n=0) Natural Subregion: Lower Boreal Highlands Ecosection: LBHb Boreal
General Description There is little open water in the Lower Boreal Highlands subregion (<1%) (Natural Regions Committee 2006) so marshes are not common throughout the subregion and are dominated by emergent sedges and rushes. The marsh ecosite is found in level and depressional areas and around the shorelines of water bodies and riparian zones. The water is above the rooting zone for at least a portion of the growing season.
Successional Relationships The marsh ecosite is near the beginning stages of hydrarch succession. The marsh ecosite can be thought of as successionally stable with changes in plant community composition being determined largely by disturbance to the water regime.

LBHf Foothills Ecosection (n=255) Natural Subregion: Lower Boreal Highlands General Description This ecosection includes ecodistricts that are closer to the foothills climate and physiography and were previously classified within the Lower Foothills subregion (Ecodistricts of Alberta 1995). These ecodistricts include Chinchaga Plain, Clear Hills Upland, Milligan Upland, Notikewin Plain and Rainbow Lake Plain and are located in the Northwestern part of the province.
Successional Relationships The foothills ecosection is dominated by lodgepole pine forests and has little presence of jack pine. In contrast the boreal ecosection is the major zone of hybridization for jack pine and lodgepole pine and both species are present. The hairy wildrye ecosite is also found within the foothills ecosection, but was not described within the boreal ecosection. The hairy wildrye ecosite is described in both the Upper and Lower Foothills subregions (Beckingham et al. 1996).

a blueberry-bearberry (subxeric/poor) (n=2) Natural Subregion: Lower Boreal Highlands Ecosection: LBHf Foothills
General Description This ecosite has dry conditions with rapidly drained acidic soils and poor nutrient status due to the coarse-textured (sands and loamy sands) morainal and glaciolacustrine parent materials (O'Leary et al. 2002). This ecosite is similar to the blueberry ecosite described in the boreal subregions (Beckingham and Archibald 1996). Plants that are indicative of the nutrient-poor substrate include bearberry, lichen, bog cranberry, and blueberry. Open-canopied aspen and lodgepole pine stands dominate this ecosite that commonly has a carpet of lichens, bearberry or blueberry covering the forest floor. This ecological site is not common in the Lower Boreal Highlands as the majority of the subregion is dominated by medium textured glacial till deposits on slopes of the northern and eastern hill systems. Allen and Johnson (2007) felt this ecological site was common in the boreal ecosection of the Lower Boreal Highland subregion but was only described from a few sandy terraces adjacent to a number of lakes in the Birch Hills. Site index for this ecological site is from the Lower Foothills subregion (Beckingham et al. 1996).
Successional Relationships Due to the dry nature of this ecosite, succession to a white spruce canopy is slower than the fire return interval. Pine is maintained for relatively long periods from colonization of the site after fire to the climax stages. The pine phase of this ecosite can be considered a fire edaphic climax. The pine, aspen, and white birch-dominated phases of this ecosite may, in some cases, succeed to white spruce, however the process is expected to be relatively slow due to the dry nature of these sites. A shrub phase of this ecosite dominated by blueberry and bearberry may exist for an extended period of time after a fire.

LBHfD1 Aw-Sw-Pl/Bearberry (n=1) (Populus tremuloides-Picea glauca-Pinus contorta/Arctostaphylos uva-ursi) This community type was found on a small, sandy hill crest and is not common in the foothills ecosection of the Lower Boreal Highlands subregion. Succession in the absence of disturbance will be to lodgepole pine and eventually white spruce. Lodgepole pine is expected to be an associate in stands of this type growing on sandy or coarse textured soils.

b hairy wild rye (submesic/medium) (n=26) Natural Subregion: Lower Boreal Highlands Ecosection: LBHf Foothills
General Description This ecosite tends to be submesic as a result of sloped, southerly aspects, relatively course-textured morainal, glaciofluvial or glaciolacustrine parent materials, or a combination of both (O'Leary et al. 2002). This ecosite is similar to the hairy wildrye ecosite described in the Lower Foothills subregion (Beckingham et al. 1996) and tends to be found on level, mid to upper slope positions. The nutrient regime varies from poor to rich with richer sites being associated with higher covers of hairy wild rye and deciduous trees. This ecosite is intermediate in both moisture and nutrient regime between the blueberry-bearberry ecosite (a) and the low-bush cranberry ecosite (d). Site index for this ecological site is from the Lower Foothills subregion (Beckingham et al. 1996).
Successional Relationships The pine- and aspen-dominated phases of this ecosite may, in some cases, succeed to white spruce but the process is slow due to the dry nature of this ecosite.

c Labrador tea (mesic/poor) (n=23) Natural Subregion: Lower Boreal Highlands Ecosection: LBHf Foothills
General Description This ecosite tends to have a submesic to mesic moisture, nutrient-poor to medium substrate. Labrador tea and bog cranberry are indicative of the relatively acidic surface soil conditions. This ecosite occurs in upland (midslope and upper slope) or level topographic positions dominantly on morainal, glaciolacustrine or glaciofluvial parent materials. There is commonly a two-tiered even-aged canopy where the faster growing lodgepole pine comprise the higher layer and the slower growing black spruce form a secondary canopy below the pine. While the Labrador tea-mesic ecosite (c) has plant community types similar to the Labrador tea-subhygric ecosite (g), the subhygric ecosite tends to occur in lower topographic positions, commonly has mottles near the soil surface, has a thicker organic layer, and tends to be dominated by black spruce rather than pine. Site index for this ecological site is from the Lower Foothills subregion (Beckingham et al. 1996).
Successional Relationships Successionally mature stands that develop on this ecosite may be dominated by black spruce. Residual pine occurring in the climax community are generally very old. The successionally mature stage is rare due to high fire frequency.

d low-bush cranberry (mesic/medium) (n=118) Natural Subregion: Lower Boreal Highlands Ecosection: LBHf Foothills
General Description This is the reference ecosite for the Lower Boreal Highland/Foothills ecosection because it commonly has a mesic moisture regime and a medium nutrient regime. Generally, these sites have moderately fine to fine-textured till, glaciofluvial or glaciolacustrine parent materials. Site index for this ecological site is from the Lower Foothills subregion (Beckingham et al. 1996).
Successional Relationships This ecosite is similar successionally to the low bush cranberry ecosite described in the Lower Foothills subregion (Beckingham et al. 1996). Pioneer deciduous tree species such as aspen, balsam poplar, and white birch are replaced by lodgepole pine, white spruce and balsam fir as these sites develop successionally. Along with a change in canopy composition is a change in understory structure and understory species composition and abundance. Generally, as a stand successionally matures, the coniferous canopy cover increases, and understory species structure and diversity declines. This results in stands with low cover of shrub, forb, and grass species and high moss cover. On the agricultural fringe of the Lower Boreal Highlands subregion these sites are often cleared, tilled and seeded to tame forage species. Once developed perennial pastures are often stable successionally for long periods.

LBHfE10 Pl/Alder (n=11) (Pinus contorta/Alnus crispa) This community type occurs on fairly loamy to coarse, moderately well drained parent material. It corresponds to Aw-Sw-Pl/green alder (Beckingham et al 1996) in the Lower Foothills subregion and is thought to represent a transition from the modal aspen to the dry lodgepole pine dominated types. The presence of green alder indicates a slightly higher moisture availability, compared to the modal, likely created by an impermeable soil layer within about 2m of the soil surface.

LBHfC5 Aw/Buffaloberry (n=14) (Populus tremuloides/Shepherdia canadensis) This aspen community type is dominated by an understory of buffalo-berry and is similar to communities described in the Lower Foothills and Dry Mixedwood subregions. Beckingham (1993) described a similar community type (Aw/Buffalo-berry) in the Boreal. This type had vegetative affinities with the Aw/Rose-Low Bush Cranberry/Tall Forb described in the Lower Foothills (Lane et al. 2000) type due to the common mesic substrate characteristics, but the buffalo-berry type was slightly drier, acidic (pH 5.3) and nutrient poor. This community type is not as productive as other mesic/medium Aspen types.

LBHfC6 Aw/Alder (n=8) (Populus tremuloides/Alnus crispa) This community type is generally found at low to mid slope elevations on sites with northerly aspects. It tends to be dominated by green alder in the tall shrub layer and rose & raspberry in the low shrub layer. Wild sarsaparilla dominates the forb layer. EMA (1993) described a similar community type (Aw(Pb)/Green Alder/Wild Sarsaparilla) throughout the Low Boreal Cordilleran ecoregion. They found this type on well drained Orthic Grey Luvisols and Eutric Brunisols (Balsam poplar occurred as a codominant in the overstory on imperfectly drained, luvisolic Gleysols). This community type can be found in the boreal and foothills subregions of the province.

LBHfC7 Aw/Low-bush cranberry (n=30) (Populus tremuloides/Viburnum edule) This community type appears to be the modal aspen type on mesic well to moderately well drained, nutrient medium to rich, undisturbed sites throughout the foothills ecosection. Beckingham et al (1996) described a similar community type (Aw/Low Bush Cranberry) in both the boreal and foothills subregions. Later seral stages will likely succeed to a mixed Aw-Sw/rose/forb type and climax to a Sw/moss dominated community.

LBHfD7 Pl-Sw-Aw/Alder (n=4) (Pinus contorta-Picea glauca-Populus tremuloides/Alnus crispa) This community type occurs on loamy textures, moderately well drained parent material. It corresponds to Aw-Sw-Pl/green alder (Beckingham et al 1996) and is thought to represent a transition from the modal aspen to the dry lodgepole pine dominated types. The presence of green alder indicates a slightly higher moisture availability, compared to the modal, likely created by an impermeable soil layer.

LBHfD8 Aw-Sw-Pl/Buffaloberry (n=3) (Populus tremuloides-Picea glauca-Pinus contorta/Shepherdia canadensis) This community type is similar to Aw-Sw-Pl/buffalo-berry/hairy wild rye described by Beckingham et al (1996). The prominence of aspen indicates that it is relative early succession as lodgepole pine and later white spruce will begin to dominant with later succession stands. The diversity of shrubs has restricted the herbaceous growth to low forbs with little grass cover.

LBHfD9 Aw-Sw-Pl/Moss (n=13) (Populus tremuloides-Picea glauca-Pinus contorta/Hylocomium splendens) This community type is ecologically similar to the Pl-Aw/Hylo spl - Pleu sch association of Beckingham (1993). However, this community type is more successionally advanced and white spruce is well established in the stand. As this forest grows older, white spruce will eventually replace lodgepole pine as the dominant tree species. This community type represents an intermediate state between a young seral deciduous stand and a climax white spruce - balsam fir stand.

LBHfE6 Sw/Alder (n=3) (Picea glauca/Alnus crispa) This community type occurs on loamy, moderately well drained parent material. It corresponds to Aw-Sw-Pl/green alder (Beckingham et al 1996) in the Lower Foothills subregion and is thought to represent a transition from the modal aspen and mixedwood dominated types. The presence of green alder indicates a slightly higher moisture availability, compared to the modal, likely created by an impermeable soil layer.

LBHfE7 Sw-Pl/Moss (n=1) (Picea glauca-Pinus contorta/Hylocomium splendens) This community type is ecologically similar to the Pl-Aw/Hylo spl - Pleu sch association of Beckingham (1993). However, this community type is more successionally advanced and white spruce is well established in the stand. As this forest grows older, white spruce will eventually replace lodgepole pine as the dominant tree species. This community type represents an intermediate state between a young seral deciduous stand and a climax white spruce - balsam fir stand.

LBHfA2 Kentucky bluegrass-Timothy/Dandelion (n=2) (Poa pratensis-Phleum pratense/Taraxacum officinale) Perennial crops are rare in the Lower Boreal Highlands subregion because of the short growing season. This community type seems to have developed because of either poor establishment for seeded species or prolonged heavy grazing. Although tall productive species such as timothy, brome grass and orchard grass were likely seeded on the site, grazing resistant species such as Kentucky bluegrass, dandelion and clover now dominate. Continued heavy grazing will likely allow disturbance species and/or weedy species to continue to invade. Although these sites may be productive, the ecological sustainable stocking rate has been reduced to help improve range health.

e red osier dogwood (subhygric/rich) (n=13) Natural Subregion: Lower Boreal Highlands Ecosection: LBHf Foothills
General Description The dogwood-fern ecosite is subhygric and nutrient medium to rich. These sites are commonly found on level or depressional areas near the base of slopes or near watercourses that recieve nutrient rich seepage or are occassionally flooded. Fine textured till, morainal and lacustrine parent materials are common. Site index for this ecological site is from the Lower Foothills subregion (Beckingham et al. 1996).
Successional Relationships Succession to conifer on these rich sites proceeds slowly because of the proliferation of grass, forbs and shrubs after disturbance. These sites are often dominated by balsam poplar, river alder, willow and red osier dogwood with the succession to spruce in the absence of disturbance.

LBHfC10 Pb-Aw/Red osier dogwood-Willow (n=1) (Populus balsamifera-P. tremuloides/Cornus stolonifera-Salix scouleriana) Beckingham and Archibald (1996) and Thompson and Hansen (2002) found this community type on mid to lower slope topographic positions or near wetlands, water bodies or water courses where they receive nutrient-rich seepage or flood waters for a portion of the growing season. Thompson and Hansen (2002) suggest that Sw will replace Pb with time (succession).

LBHfC8 Pb/Willow (n=5) (Populus balsamifera/Salix scouleriana) This community type is found on lower slope seepage areas with moderately moist, nutrient rich soils. It is often found in association with other moisture-adapted shrub species such as honeysuckle, dogwood, and to a lesser extent alder. This may be found upslope, in transition, from willow shrubland areas and is an important cover and browse for moose.

LBHfC9 Pb-Aw/Alder (n=2) (Populus balsamifera-P. tremuloides/Alnus crispa) This community type occupies mid to lower-slope positions and is easily recognized in the field by the dominance of alder. Green alder (Alnus crispa) would be more abundant than river alder (Alnus tenuifolia) on midslope positions, and the opposite would be true on the lower slope positions. However, tree, forb and grass layers are very similar at both mid and lower-slope positions. This community type is similar to the Pb-Aw/Alder type described by Beckingham (1993) and the Aw (Pb)/ Green alder/ Wild Sarsaparilla and Pb-Aw/ Bracted Honeysuckle- River alder community types described by Environmental Management Associates (EMA) (1993). This community type is found on mesic to hygric, moderately well-drained sites. The moisture regime is slightly wetter than the Pb-Aw/Rose community type, which likely accounts for the increased growth of alder.

LBHfB1 Shrubby willow-River alder (n=1) (Salix arbusculoides-Alnus tenuifolia) This community represents lowland sites surrounding open water or nutrient rich river flood plains This community is part of the red osier dogwood (e) ecological site. River alder is the defining species with horsetail common in the understory. These sites have high diversity. Succession, in the absence of disturbance will likely be to balsam poplar and eventually white spruce.

f horsetail (hygric/rich) (n=8) Natural Subregion: Lower Boreal Highlands Ecosection: LBHf Foothills
General Description The horsetail ecosite is wet and nutrient rich. These sites are commonly found on till, lacustro-till, fluvial or glaciolacustrine parent materials where flooding or seepage enhances the substrate nutrient supply. With high water tables, wet soil conditions, and Gleysolic soils, organic matter tends to accumulate. Horsetails commonly form a blanket over the forest floor. Site index for this ecological site is from the Lower Foothills subregion (Beckingham et al. 1996).
Successional Relationships Succession on these sites is largely controlled by high soil water content. Some sites that have peaty soils and may have taken hundreds of years to develop. When the trees are removed, the water table may rise making tree establishment because bluejoint and shrubs take over the site. White spruce forms the canopy in the last successional stage. Shrub phases tend to be dominated by tall willow and alder species.

g Labrador tea-horsetail (hygric/medium) (n=7) Natural Subregion: Lower Boreal Highlands Ecosection: LBHf Foothills
General Description The Labrador tea/horsetail ecosite is wet and commonly has a medium to poor nutrient regime. These sites are commonly found on lower topographic positions on level glaciolacustrine, till, or organic parent materials. With wet substrate conditions, Gleysolic soils are common and organic matter tends to accumulate. Along with Labrador tea, horsetails commonly form a blanket over the forest floor. The Labrador tea-hygric ecosite has plant community types similar to the Labrador tea-mesic ecosite, the hygric ecosite tends to occur in lower topographic positions, has mottles in the top 25 cm of soil, has a thicker organic layer, and may be dominated by black spruce rather than pine. Site index for this ecological site is from the Lower Foothills subregion (Beckingham et al. 1996).
Successional Relationships Young and mature stands developing in this ecosite often have a component of black spruce. The black spruce is often the same age as the pine but forms a secondary canopy due to slower growth rates. Successionally mature stands are dominated by black spruce with a small component of residual pine (Beckingham and Archibald 1996). After disturbance, these sites are commonly colonized by hydrophytic species such as willow, marsh reed grass, and sedges in the shrub phase.

LBHfB3 Willow-Labrador tea/Golden moss (n=2) (Salix spp.-Ledum groenlandicum/Tomenthypnum nitens) This community type occurs in association with lowland areas adjacent to poor fens where the nutrient regime is medium. The water table under this community type is high during the entire growing season, but flooding is rare. Succession within this community type is to white spruce and black spruce but is inhibited due to poor drainage. This community was included in the shrub phase because black spruce is only found in the mid and tall shrub layer and has a low canopy cover.

h bog (subhydric/poor) (n=21) Natural Subregion: Lower Boreal Highlands Ecosection: LBHf Foothills
General Description The bog ecosite commonly has organic soils consisting of slowly decomposing peat moss. They are poorly to very poorly drained and have a very poor to poor nutrient regime. This ecosite occupies level areas and depressions where water tends to be stagnant and impeded drainage or high water tables enhance the accumulation of organic matter. Stunted black spruce form a sparse canopy on the treed phase (k1) of the bog ecosite. Bog ecosites are less common in the Lower Boreal Highlands subregion (Natural Regions Committee 2006) and tend to be dominated by the tree and shrub phases. Site index for this ecological site is from the Lower Foothills subregion (Beckingham et al. 1996).
Successional Relationships The bog ecosite is an edaphic climax that is maintained by high water tables. The hydrarch succession to the bog ecosite is extremely slow.

General Description This ecological site phase currently has no data and graminoid bogs have not been described in the Boreal Natural Region. This ecological site phase was created for photo interpretation of vegetation for Alberta Vegetation Inventory (AVI) and Primary Land Vegetation Inventory (PLVI) if the interpreters call for a mapcode of 9B (Hydric/very poor). If interpreted in the various vegetation land cover inventories it will provide a spatial location in which to sample.

i poor fen (subhydric/medium) (n=13) Natural Subregion: Lower Boreal Highlands Ecosection: LBHf Foothills
General Description The poor fen ecosite is intermediate in nutrient regime between the bog (h) and the rich fen (j) ecosites and as such has species characteristic of both. Drainage is poor to very poor, however, there is some movement of water through the substratum. This ecosite occupies level and depressional areas where impeded drainage or high water tables enhance the accumulation of organic matter. This organic matter consists of a combination of bog-type organic matter (peat moss) and rich fen-type organic matter (sedges, golden moss, tufted moss, and brown moss). Both the black spruce and/or tamarack that dominate a sparse canopy on the treed phase (i1) of the poor fen ecosite are stunted and generally considered unmerchantable (Beckingham and Archibald 1996).
Successional Relationships The hydrarch succession characteristic of this ecosite occurs over periods of hundreds to thousands of years. Thus, recovery from disturbance is extremely slow. Changing hydrologic regimes that can result from disturbance influence the direction and rate of succession. As these systems depend on water flow through them, impeding this flow can result in reduction or elimination of tree cover and changes in the shrub, forb and grass layers(Beckingham and Archibald 1996).

LBHfE13 Sb-Lt/Willow/Horsetail (n=5) (Picea mariana-Larix laricina/Salix spp./Equisetum arvense) This community type is transitional between the rich fen and the bog ecological sites. Rich fens tend to be dominated by tamarack, willow and golden moss, whereas, bogs are dominated by black spruce, Labrador tea and peat moss. The presence of a high cover of willow, tamarack and horsetail in this community indicate the richer nutrients compared to the communities within the bog ecosite.

LBHfB5 Bog birch/Sedge/Peat moss (n=7) (Betula glandulosa/Carex aquatilis/Sphagnum spp.) This community type is found in moist depressions and has species characteristic of bogs (peat moss, Labrador tea) and species characteristic of fens (water sedge, willow and bog birch). As organic matter accumulates these sites dry out, black spruce, tamarack, balsam poplar or paper birch establish (Beckingham 1993). Bog birch dominated communities are found in both the Lower Foothills and Central Mixedwood subregions and are associated with richer sites.

j rich fen (subhydric/rich) (n=24) Natural Subregion: Lower Boreal Highlands Ecosection: LBHf Foothills
General Description The rich fen ecosite is characterized by flowing water and alkaline nutrient-rich conditions. The soil is composed of organic matter derived from decomposing sedges, as well as golden, tufted, and brown mosses. This ecosite occupies level and depressional areas where the water table is at or near the surface for a portion of the growing season. Tamarack dominates the canopy on the treed phase while dwarf birch or willow form the canopy of the shrubby phase, and sedges dominate the graminoid phase of the rich fen ecosite.
Successional Relationships The rich fen is an early stage in hydrarch succession. Species composition, and direction and rate of succession changes with the changing hydrologic regime. As with other wetlands, rich fens have slow successional rates, so recovery from disturbance may also be slow.

LBHfB6 Bog birch-Willow/Sedge/Golden moss (n=6) (Betula glandulosa-Salix spp/Carex aquatilis/Tomenthypnum nitens) This community is similar to the previously described Bog birch (LBHfB5) community, but has richer nutrients because of the flowing water through the site. The lack of peat moss and the presence of golden moss indicate the change in nutrient status between the two community types. Willow and bog birch become established at the edges of the sedge meadow due to the shorter duration of standing water. Increased flooding and prolonged water logging may result in the disappearance of willow and a transition to a water sedge meadow. As organic matter accumulates these sites dry out, black spruce, tamarack, balsam poplar or paper birch establish (Beckingham 1993).

LBHfB7 Willow/Sedge/Golden moss (n=12) (Salix spp./Carex aquatilis/Tomenthypnum nitens) This community type is very similar to the previously described bog birch (LBHfB6) dominated community but lacks the high cover of bog birch. The reduced bog birch cover may indicate the slightly more alkaline and richer condition of this community type. This community type is found along the edges of sedge meadows and in moist depressions. Willow becomes established at the edges of the sedge meadow due to the shorter duration of standing water.

LBHfA1 Water Sedge (n=4) (Carex aquatilis) This community type is found in areas that are flooded for most of the growing season. It occurs on wetter sites than the Marsh Reed Grass dominated community type described in the Lower Foothills subregion (Lane et al. 2000). Succession within this community type is very slow and proceeds with organic matter accumulations (Beckingham 1993). Therefore, this community type can be considered the potential natural vegetation for the site. As organic matter accumulates and the edges dry willow will invade into the edge of this community type.

LBHfB8 Willow/Sedge-Kentucky bluegrass (n=1) (Salix bebbiana/Carex aquatilis-Poa pratensis) This community type occurs on the drier edges of wet sedge meadows and Willow - Bog Birch/Sedge or Willow/Marsh reedgrass dominated community types, where it is easy for livestock to access. The heavy grazing regime has favoured the growth of Kentucky bluegrass and dandelion. Continued heavy grazing pressure will eventually lead to a community type dominated by agronomic species (timothy, kentucky bluegrass, clover and dandelion) in the understory.

LBHfB9 Willow/Dandelion/Timothy (n=1) (Salix spp./Taraxacum officinale/Phleum pratense) This community is similar to the previously described Willow/Sedge-Kentucky bluegrass (LBHfB8) dominated community but has been heavily grazed for a longer period of time. Heavy grazing will move the community towards a Kentucky Bluegrass/ Clover - Dandelion dominated community type. This community type is considered to be in fair to poor range condition and is generally very productive for domestic livestock, but stocking levels should be reduced on these sites to allow for recovery.

k marsh (hydric/rich) (n=0) Natural Subregion: Lower Boreal Highlands Ecosection: LBHf Foothills
General Description There is little open water in the Lower Boreal Highlands subregion (<1%) (Downing and Pettapiece 2006) so marshes are not common throughout the subregion and are dominated by emergent sedges and rushes. The marsh ecosite is found in level and depressional areas and around the shorelines of water bodies and riparian zones. The water is above the rooting zone for at least a portion of the growing season.
Successional Relationships The marsh ecosite is near the beginning stages of hydrarch succession. The marsh ecosite can be thought of as successionally stable with changes in plant community composition being determined largely by disturbance regime.
