Summary
This report details an aquatic environmental values assessment that was undertaken for freshwater-dependent ecosystems in the Macquarie River catchment (upstream of the confluence with the Lake River) to support the development of a Water Management Plan. The environmental values were almost entirely derived from an interrogation of the Conservation of Freshwater Ecosystem Values (CFEV) database. This database objectively identifies important environmental values which can be used to guide the development of a priori objectives for environmental flows assessments.
Freshwater-dependent ecosystems in the Macquarie River catchment include rivers, wetlands, waterbodies and a single karst system. Generally, freshwater ecosystems in the upper reaches of the Macquarie catchment, notably upstream of the Tooms River confluence and in the headwaters of the Glen Morriston Rivulet, are in reasonable condition. Conversely, freshwater ecosystems in the remainder of the catchment, which includes basically all of the lowland areas, are in poor condition.
This assessment shows that although many freshwater-dependent ecosystems in the Macquarie River catchment have been highly modified hydrologically and physically, several unique ecosystems support a wide variety of flora and fauna of high conservation value. The main environmental values that were identified by the CFEV database relate to the distinctive riverine geomorphic characteristics of the catchment, as well as remnant riparian tree assemblages, particularly in the upper reaches of the Macquarie and Elizabeth catchments. Significant plant species include a number of endemic threatened flora species and shrubby Eucalyptus ovata and Eucalyptus rodwayi forests. Endemic, and in some instances threatened, fish (Swan galaxias), frogs (green and gold frog and southern toadlet) and invertebrates (including two caddisflies and the South Esk freshwater mussel) occur in various rivers and wetlands within the catchment. The wetlands and waterbodies that make up the Ellinthorpe Plains Lagoon Complex (in the upper Isis catchment) are all listed as important bird sites in the CFEV database.
Catchment overview
The Macquarie River catchment is located in central eastern Tasmania. This assessment focuses on the region of the catchment above the confluence with the Lake River, which covers an area of approximately 2697 km2. The main tributaries of the Macquarie River in this region include the Blackman River, Isis River, Elizabeth River and Glen Morriston Rivulet. From its headwaters just south of Lake Leake in the Eastern Tiers, the Macquarie River flows south through dolerite hills to the confluence with the Tooms River. This section of the river contains largely intact riparian vegetation (mostly dry sclerophyll forest communities) and, generally, is in good condition. Downstream of this area, the river has a low-gradient, often meandering channel as it flows north-west over Launceston Tertiary Basin sediments to the confluence with the Lake River. In this region, extensive agriculture has led to highly degraded riparian areas, with floodplains often being cleared of most native vegetation to the river bank. Where there is riparian vegetation, it is often composed of exotic weeds (such as European gorse and willow trees), and erosion is common where riparian vegetation is non-existent.
Currently, there are more than 300 water allocations on the Macquarie River above the Lake River confluence; these are used for irrigation and small-scale stock and domestic supplies, as well as the municipal needs of the townships of Ross and Campbell Town. Currently, the Elizabeth Macquarie Irrigation Trust manages the water in the main channels of the Elizabeth and Macquarie rivers to the confluence of the Lake River, which is primarily supplied by the impoundments in the headwaters of the
4
catchment, Lake Leake and Tooms Lake. Blackman Water Pty Ltd is currently being established to manage the water in the main stem of the Blackman River between the Blackman Dam and the confluence of the Blackman River and the Macquarie River, including that stored in the Blackman Dam. The Department of Primary Industries and Water (DPIW) manages the licensing of off-stream storages in the region (i.e. farm dams), direct takes from tributaries of the Macquarie River and the high flow water in the region. Trout fishing is the principal recreational activity in the riverine environments of this region.
Methodology
Water Management Regions
After consultation with the Water Management and Water Policy and Planning Branches of DPIW, the Macquarie catchment was divided into five Water Management Regions (WMRs) for management purposes (Figure 1). These regions have been used throughout the report as spatial units for examining environmental values in the catchment, and were determined using a combination of the following:
• Existing water management areas (e.g. irrigation districts and old water districts)
• Practical and logical management areas based on experience of managing water resources in this catchment
• Confluence of streams (nodes), as these form the basis of water trading zones
• Areas with similar riverine geomorphology
Therefore, based on the above considerations, the five WMRs that will be referred to in this report are as follows (Figure 1):
1. Upper Macquarie River including Tooms Lake and all tributaries upstream of the confluence with the Elizabeth River except the Blackman River and its tributaries.
2. Blackman River and its tributaries.
3. Isis River and its tributaries.
4. Macquarie River downstream of Elizabeth River, including all tributaries down to the confluence with Lake River.
5. Elizabeth River and its tributaries, including Lake Leake.

CFEV database interrogation
Conservation values in the Macquarie River catchment were examined by interrogating the Conservation of Freshwater Ecosystem Values (CFEV) database (CFEV, 2005). The CFEV database provides an objective means to identify the ecological values in a catchment (DPIW, 2008a) and, therefore, helps to define the objectives of water management activities and the aims of environmental flows that may be provided under a Water Management Plan.
The CFEV framework includes condition as Naturalness, which is an index of the ecosystem’s departure from modelled pre-European settlement condition. Ecosystems are given a Naturalness score (N-score), which is assigned a category, so a High N-score corresponds to a relatively unmodified ecosystem. Two ratings of conservation value are provided by the CFEV database, both of which were used to identify values within the Macquarie catchment. The Representative Conservation Value (RCV) is a value based on the rarity and condition of the ecosystem and the important biophysical class associated with it. The Integrated Conservation Value (ICV) is a value based on the RCV combined with the presence of any Special Values (SVs; such as threatened species) (DPIW, 2008a).
To provide details of the freshwater-dependent ecosystems of greatest conservation value (i.e. best examples of biophysical classes), only A-band RCV and High or Very High ICV ecosystems were examined in this assessment. Other ecosystems that have B- or C-band RCV in the Macquarie River catchment may also be of conservation value, but, according to the CFEV database, may not be the best examples of biophysical classes; therefore, these were not included in the assessment. The values of all river sections in the catchment (i.e. all stream orders) were assessed, as some SVs and unique biophysical classes may be found only in headwater streams, and it was considered relevant to provide details on all freshwater ecosystem values within the catchment. Further aquatic values, primarily relating to flora and fauna species which are listed under State (Tasmanian Threatened Species Protected Act 1995) and federal (Commonwealth Environment Protection and Biodiversity Conservation Act 1999) threatened species legislation, were identified by interrogating the Natural Values Atlas (DPIW, 2008b) and the threatened species lists of DPIW (http://www.dpiw.tas.gov.au/inter.nsf/WebPages/SJON-58E2VD?open; accessed on 8 August 2008).
It is important to note that in the CFEV database, biophysical classes are largely modelled to represent pre-European settlement conditions. As such, it is acknowledged that the identified biophysical classes should be accompanied by field studies to verify their presence and condition. To assist with this in the Macquarie catchment, a validation study, which focused on selected biophysical classes in the catchment, has recently been undertaken (Davies et al., 2007); the results of the validation study should be cross-referenced with this report.
The current report uses a number of terms that are specific to the CFEV Project; definitions of these terms are provided in Appendix 7. For further information about the CFEV database and how it was developed see the CFEV website (http://www.dpiw.tas.gov.au/inter.nsf/ThemeNodes/CGRM-7JH6CM?open; accessed on 15 October 2008).

Freshwater ecosystem values in the Macquarie catchment
Freshwater-dependent ecosystems in the Macquarie River catchment include rivers, wetlands, waterbodies and a single karst system. Generally, freshwater ecosystems in the upper reaches of the Macquarie catchment, notably upstream of the Tooms River confluence and in the headwaters of the Glen Morriston Rivulet, have High N-scores and, hence, are in reasonable condition (Figure 2). Additionally, in other regions of the catchment, the headwaters of several tributaries of the Macquarie River, such as the Blackman River, the Isis River and Blanchards Creek, also have High N-scores (Figure 2). Freshwater ecosystems in the remainder of the catchment, which includes basically all of the lowland areas, have Low N-scores; thus, are in poor condition. It should be noted, that any man-made ecosystem (such as an impounded natural wetland or lake) will be assigned a Low N-score, as it has been heavily modified from its natural condition. Hence, both Lake Leake and Tooms Lake have Low N-scores (Figure 2).
Freshwater ecosystems of A-band RCV are mostly concentrated in the upper Macquarie catchment, particularly in the Macquarie River above Tooms Lake and in the Elizabeth catchment above Chimney Hill (Figure 3). Additionally, relatively small river reaches, waterbodies or wetlands in the upper regions of the Blackman River, the Isis River and Blanchards Creek catchments, are also A-band RCV (Figure 3). If an ecosystem’s associated important biophysical class is the best example of its type in Tasmania (despite being in poor condition) then the RCV may be elevated to A-band. Examples of this can be seen in the waterbodies Tooms Lake and Lake Leake, and also in the mid-reaches of the Macquarie River downstream of the township of Ross (Figure 3). Freshwater ecosystems in the remainder of the catchment, which includes basically all of the lowland areas, have B- or C-band RCV.
Similar to the patterns of RCV across the Macquarie catchment, freshwater ecosystems of Very High ICV mostly occur in the upper reaches of the Macquarie and Elizabeth rivers, with additional isolated river sections in the mid-reaches of the Macquarie River and in the upper reaches of the Blackman River (Figure 4). Wetlands and waterbodies of Very High ICV occur mainly in the mid-reaches of the Upper Macquarie WMR and in the upper reaches of the Isis WMR (Figure 4). The presence of SVs in an ecosystem will increase its ICV in comparison to its RCV. Examples of this in the Macquarie catchment occur on the main stem of the Elizabeth River, where some B- and C-band RCV ecosystems have been elevated to Very High ICV with the inclusion of SVs (Figure 4). Despite there being some ecosystems of High ICV across the catchment, most of the remaining freshwater ecosystems have Low or Medium ICV.

Freshwater ecosystem values in water management regions
A summary of the freshwater-dependent ecosystem values of the five WMRs in the Macquarie catchment above the Lake River confluence is provided in Table 1. Ecosystem values, which were derived from an interrogation of the CFEV database, may describe the important biophysical class of an ecosystem, or SVs present within the ecosystem. Complete CFEV output tables for each WMR are presented in Appendices 1-5.
Upper Macquarie WMR
The important biophysical class associated with the A-band RCV riverine ecosystems in this region is a fluvial geomorphic river type found in dolerite country in the Midlands area (Figure 5). This biophysical class makes up approximately 18% of the river sections in the region (Appendix 1). Important biophysical classes associated with wetlands are mostly tree assemblages (Figure 5), particularly wet and dry sclerophyll vegetation.
High numbers of SVs occur in this WMR, including the Swan galaxias and green and gold frog, the endemic South Esk freshwater mussel, two endemic threatened flora species (and several other threatened flora species and communities), and a priority geomorphic feature (Long Marsh “den sequence”) (Appendix 1).
Blackman River WMR
The river sections of A-band RCV are restricted to a small area in the upper catchment, where the Blackman River flows off the Western Tiers (Figure 6). In this area, the important biophysical class is a fluvial geomorphic river type. The important biophysical classes associated with wetlands of A-band RCV are mostly tree assemblages (Figure 6).
The presence of SVs in the Blackman WMR has elevated a number of ecosystems to High or Very High ICV (Appendix 2). These SVs include two macroinvertebrates (isopods) of conservation significance: the threatened salt lake slater and the phylogenetically distinct phreatoicid isopod. Threatened flora species and communities are also present, including an endemic threatened flora species (Tunbridge buttercup), and the lagoons near the Isis catchment (Ellinthorpe Plains Lagoon Complex) are listed as important bird sites on the CFEV database (Appendix 2).
Isis River WMR
A small portion of the upper catchment is A-band RCV and High or Very High ICV (Figure 7). Important biophysical classes include a geomorphic river class and a tree assemblage associated with the wetlands. A karst system in the west of the region is rated as A-band RCV and High ICV (Figure 7), having no associated SVs (Appendix 3). SVs associated with the High and Very High ICV ecosystems in the upper catchment include threatened flora species and communities, and a number of wetlands and waterbodies in the Ellinthorpe Plains Lagoon Complex are listed as important bird sites (Appendix 3).
12
Macquarie downstream of Elizabeth WMR
Relatively high numbers of important biophysical classes associated with freshwater ecosystems of A-band RCV occur in Macquarie downstream of Elizabeth WMR (Figure 8). These include a native fish assemblage and a macrophyte assemblage associated with broadwater habitats, as well as some tree classes and the geomorphic class which characterizes the catchment. Ecosystems of A-band RCV are mostly confined to the Blanchards Creek catchment, where a number of river sections with Low N-scores have A-band RCV, indicating that, although the area may be highly modified, it contains river sections that are among the most representative of these important biophysical classes in Tasmania.
SVs in the region include, amongst others, Swan galaxias, southern toadlet the priority geomorphic feature “The Broadwater” at Barton, a threatened caddis fly, South Esk freshwater mussel, and two endemic flora species (clasping-leaf heath and Midlands wattle) (Appendix 4).
Elizabeth River WMR
Freshwater ecosystems of A-band RCV occur almost exclusively in the upper reaches of the Elizabeth WMR, in the river sections and wetlands upstream of the Hortons Creek confluence at Chimney Hill (Figure 9). These are mostly tree assemblages and the geomorphic class typical of the Macquarie catchment (G17), but also include a first-order stream macroinvertebrate assemblage. SVs include endemic flora species, a threatened caddis fly and the green and gold frog (Appendix 5). As illustrated in the RCV and ICV maps (Figures 3 and 4), river sections of B-and C-band RCV along the main stem of the Elizabeth River have often been elevated to Very High ICV in the CFEV database. This indicates the presence of outstanding and/or multiple SVs in these river sections.

Lake ecosystem values
The artificial impoundments Tooms Lake (Figure 10) and Lake Leake (Figure 11) were created in the 1830s and 1880s, respectively. Prior to its impoundment, Tooms Lake was a natural lagoon, whereas Lake Leake was a ‘bog’ or wetland. These waterbodies now support unique freshwater ecosystems. The CFEV database provides six biological and physical classes which characterise waterbodies across Tasmania (DPIW, 2008a). These classes represent: the physical attributes of the waterbody, crayfish assemblages, native fish assemblages, native tree assemblages and the Tyler corridor (which reflects biochemical regionalisations). The important biophysical class of a waterbody is that of which the waterbody is considered to be the most representative. The important biophysical class in both Lake Leake and Tooms Lake is the waterbody physical class Wb15 (Table 2), which describes the surface area, depth, and shoreline development of the lakes. Other than the important biophysical class, all other biophysical classes are the same in both lakes, except the native fish assemblage class. According to the CFEV database, Tooms Lake contains no native fish, or has few species at very low densities (F0), whereas Lake Leake contains short-finned eels (Table 2). Special Values in both lakes are threatened flora species and priority flora communities associated with the riparian vegetation. Additionally, both lakes contain platypus (Ornithorynchus anatinus) (Table 2).

Appendix 7. Terminology of the Conservation of Freshwater Ecosystem Values (CFEV) project (DPIW, 2008a).
CFEV project: The ‘Conservation of Freshwater Ecosystem Values’ project which has developed a planning and information tool (a database) to support the inclusion of freshwater values within a strategic framework for the management of Tasmania’s freshwater resources.
Biophysical class: Under the CFEV Project, biological and physical variables relating to freshwater dependent ecosystem were used to develop a ‘biophysical classification’ that is applicable at a State-wide level. For riverine ecosystems, the main biophysical classifications are for fish assemblages, geomorphic river types, aquatic plant assemblages, tree assemblages and crayfish assemblages.
Important biophysical class: The biophysical class that is the main driver for the selection and conservation value rating of an ecosystem spatial unit. This is the value of which the ecosystem spatial unit is considered to be most representative.
Naturalness: A measure of the departure from pre-European natural reference condition. This was derived for each ecosystem unit within the audit process as a single score based on a variety of sources of biophysical information. Also referred to as condition.
Representativeness: The conservation value of an ecosystem spatial unit expressed as the relative importance of that example of the particular representative component with a priority on spatial units of high naturalness. An ecosystem can be rated to be of High, Moderate or Low representativeness, where High is the first group of sites selected (highly representative), Moderate is the second (moderately representative) and Low is the remainder of sites selected (least representative).
Special Values: Unique or ‘distinctive’ conservation values other than those captured by the representativeness assessment process. These include values such as threatened flora and fauna species, threatened flora and fauna communities, priority geomorphic and limnological features and important bird sites.
Representative Conservation Value (RCV): The conservation value of an ecosystem spatial unit (e.g. river section) expressed as the relative importance of the important biophysical class with a priority on spatial units of high naturalness.
Integrated Conservation Value (ICV): The conservation value of an ecosystem spatial unit expressed as the relative importance of that unit where Representative Conservation Value has been combined with its Special Value rating.
