Abstract. Many managers today are tasked with restoring forests to mitigate the potential for

uncharacteristically severe fire. One challenge to this mandate is the lack of large-scale reference

information on forest structure prior to impacts from Euro-American settlement. We used a robust 1911

historical dataset that covers a large geographic extent (.10,000 ha) and has unbiased sampling locations

to compare past and current forest conditions for ponderosa pine and mixed conifer forests in the southern

Sierra Nevada. The 1911 dataset contained records from 18,052 trees in 378 sampled transects, totaling just

over 300 ha in transect area. Forest structure was highly variable in 1911 and shrubs were found in 54% of

transects. Total tree basal area ranged from 1 to 60 m2 ha�1 and tree density from 2 to 170 ha�1 (based on

trees .30 cm dbh). K-means cluster analysis divided transects into four groups: mixed conifer-high basal

area (MC High BA), mixed conifer-average basal area (MC Ave BA), mixed conifer-average basal area-high

shrubs (MC Ave BA Shrubs), and ponderosa pine (Pond Pine). The percentage of this 1911 landscape that

experienced high severity fire was low and varied from 1–3% in mixed conifer forests and 4–6% in

ponderosa pine forests. Comparing forest inventory data from 1911 to the present indicates that current

forests have changed drastically, particularly in tree density, canopy cover, the density of large trees,

dominance of white fir in mixed conifer forests, and the similarity of tree basal area in contemporary

ponderosa pine and mixed conifer forests. Average forest canopy cover increased from 25–49% in mixed

conifer forests, and from 12–49% in ponderosa pine forests from 1911 to the present; canopy cover in

current forest types is similar but in 1911 mixed conifer forests had twice the canopy cover as ponderosa

pine forests. Current forest restoration goals in the southern Sierra Nevada are often skewed toward the

higher range of these historical values, which will limit the effectiveness of these treatments if the objective

is to produce resilient forest ecosystems into the future.

INTRODUCTION

Throughout much of the drier, low- to mid-elevation coniferous forests in western NorthAmerica fires historically burned at intensitiesthat often left mature trees unaffected or scarredby fire, but seldom killed (Allen et al. 2002,Collins and Stephens 2007) even when precededby multi-year drought (Stephens et al. 2008).Mid-elevation forests in the Sierra Nevada, suchas those historically dominated by ponderosapine (Pinus ponderosa), Jeffrey pine (P. jeffreyi ),and other mixed conifer species commonlyburned many times per century (Van de Waterand Safford 2011) and this produced generallyopen stand structures (Figs. 1 and 2). These lowto moderate intensity fires burned for months ata time and collectively covered very large areas(Skinner and Chang 1996).

While it is clear that fires historically had astrong influence on forest structure at the stand-scale and vegetation patterns at the landscapescale, there are topographic controls on vegeta-tion, which can operate independent of fire(Show and Kotok 1929, Rundel et al. 1977).These topographic controls affect available mois-ture and temperature patterns, which in combi-nation influence vegetation composition andstructure. Elevation has long been noted as adriver of vegetation composition, which in theSierra Nevada results in greater Pinus dominancein lower elevations of the montane zone andgreater Abies dominance in the mid-to uppermontane zone (Show and Kotok 1929). Howeverwhat is actually a stronger predictor of forestcomposition in the Sierra Nevada is the trade-offbetween evaporative demand, which is affectedby slope aspect and elevation, and water supply,which is affected by soil properties and precip-itation patterns (Stephenson 1998).

In the late 19th and early 20th centuries,policies of fire exclusion, introduction of livestockgrazing, and elimination of Native Americanignitions greatly reduced fire frequencies inponderosa pine and mixed conifer forests (Ste-phens et al. 2007a). With these changes manycontemporary forests have substantially in-creased in their vulnerability to uncharacteristi-cally severe fire (Agee and Skinner 2005),exhibited primarily through the creation of largehigh severity patches. These large patches, where

most if not all of the trees are dead, can impedeconifer tree regeneration (Barton 2002, Goforthand Minnich 2008, Roccaforte et al. 2012, Collinsand Roller 2013, Crotteau et al. 2013, Crotteau etal. 2014) and predispose them for repeated highseverity fire and potentially, type conversion(Van Wagtendonk et al. 2012, Collins and Skinner2014). As a result, many forest managers todayare tasked with mitigating the potential foruncharacteristic severe fire (North et al. 2009,Stephens et al. 2013).

The methods used by managers to reduce firehazards and restore US coniferous forests areprescribed fire, mechanical treatments, and man-aged wildfire (Stephens et al. 2009). US NationalPark Service policy mandates incorporation ofnatural disturbances into management plans tomaintain parks in an unimpaired state (vanWagtendonk 2012). One obvious challenge tothis mandate is the lack of large-scale referenceinformation on forest structure prior to theimpacts from Euro-American settlement. Wherefeasible, fire history data provides historicalreference information in the context of thenatural range of variability of disturbance re-gimes (Allen et al. 2002, Reynolds et al. 2013).Based on the records preserved in trees rings (firescars and tree ages) researchers have reconstruct-ed fire regimes (Kilgore and Taylor 1979, Caprioand Swetnam 1995, Swetnam et al. 2009) andpast forest structure (North et al. 2007, Hurteauand North 2010) from forests in the southernSierra Nevada. Additionally, there is one study ingiant sequoia (Sequoiadendron giganteum)-mixedconifer forests that reported forest structurebased on a set of plots measured in 1900–1901(Stephens and Elliott-Fisk 1998); however, plotlocations used in this study were biased and arenot representative of southern Sierra Nevadamixed conifer forest as a whole. In many casesthese studies were intended to inform managersand policy makers of the historical or naturalrange of variability operating on the landscapewhich can assist in the development of restora-tion plans.

One of the biggest limitations of forest struc-ture reconstructions based on dendrochronologyis their limited spatial extents. In addition, tree-ring based reconstructions are subject to aninherent limitation brought about by only usingextant data. When there is a considerable amount

of time between the reconstruction period and

data collection, as there is with most historical

forest reconstructions in the western US (.100

years), uncertainty increases owing to sample

losses from fire, insects, disease, and decompo-

sition (Collins et al. 2011).

Large historical datasets, collected from the

field and archived, are an alternative source of

information used in forest reconstructions (e.g.,

Leiberg 1902, Wieslander et al. 1933). These

datasets sometimes allow for detailed quantita-

tive comparisons of current versus historical

forest structure and composition (Lutz et al.

2009). However, there are a number of concerns

associated with historical datasets: (1) limited

geographic extent, (2) unknown or unrepeatablestudy site selection and inventory methodolo-

gies, and (3) limited temporal depth. Finding a

historical dataset that addresses all of these

concerns would be extremely difficult, if not

impossible (Collins et al. 2011, Hagmann et al.

2013). That stated, we have identified a historical

dataset that covers a large geographic extent

(.10,000 ha) and has unbiased sampling loca-

tions. This particular dataset consists of early

timber inventories conducted by the US Forest

Service (USFS) and includes robust tree measure-

ments over large areas, which contrasts with the

reconstruction of forest structure from very low

density tree measurements from General Land

Office records (e.g., Baker 2014). In California,

these inventories were conducted ca. 1910 and

were part of the first organized assessment of all

timber resources within the then, new agency

(Collins et al. 2011).In this study we take advantage of a portion of

these early USFS timber inventories that wereconducted on what was then the Kern NationalForest (now part of the Sequoia National Forest).A comparison of current forest conditions tothose based on the early inventories can provideinformation on potential changes driven primar-ily by 20th century fire exclusion policies andharvesting. Such comparisons can provide infor-mation to managers on how close current foreststructure and composition is to a time whennatural processes operated on the landscape. Ourobjectives were to: (1) summarize historicaltimber inventory records, (2) identify distinctforest types based on forest structure and speciescomposition, and (3) compare past and currentforest conditions for ponderosa pine and mixedconifer forests at the landscape scale in thesouthern Sierra Nevada.

STUDY AREA

The forest sampled in 1911 was in theGreenhorn Mountains of the southern Sierra

Nevada. This area is characterized as west-slopeSierra Nevada ponderosa pine and mixed coniferforests (Figs. 1 and 2) consisting of ponderosapine, sugar pine (Pinus lambertiana), white fir(Abies concolor), incense-cedar (Calocedrus decur-rens), California black oak (Quercus kelloggii ), andcanyon live oak (Q. chrysolepis). The climate isMediterranean with cool, wet winters and hot,dry summers. Annual precipitation ranges from9 to 74 cm year�1, with an average of 32 cmyear�1; mean monthly temperatures range from0.98C in January to 20.38C in July (data from thePiutes Remote Automated Weather Station,2005–2011).

The study site covers 11,500 ha and topogra-phy varies within this area. Elevation in thestudy area ranges between 1430 and 2270 m. Thesouthern portion of the area is of lower elevation(1430–1980) while the northern area is higher(1560–2270). Soils in this area are predominatelycoarse-loamy well-drained dystric xerochrepts(under taxonomic order of inceptosols). Prior tothe late 1800s fire was common in this region,with a mean point fire return interval ofapproximately 5–20 years (Kilgore and Taylor

1979, Caprio and Swetnam 1995). With the onsetof fire exclusion fire was largely removed fromthe study area.

Early land use information from the Green-horn Mountains is provided by records from theSequoia National Forest (USDA 2013; Jim Whit-field, Ecosystem Staff Officer, Sequoia NationalForest, personal communication, 2014). Small por-tions of the Greenhorn Mountains were loggedusing only wagons and horses in the late 19thand early 20th centuries. There was no railroadlogging in this area. The nearest record ofrailroad logging is on the Hume Lake RangerDistrict which is approximately 75 km northwestof the study site (Otter 1963, Johnston 1997).Most of the earliest logged areas in the Green-horn Mountains were located near mining campsaround Lake Isabella that are not included in the1911 transects. Other areas logged prior to 1911were located at lower elevations that were moreaccessible by early roads and were used toconstruct houses in the growing town of Bakers-field, California. The historic inventory recordscollected for this study included 15 surveytransects that mentioned prior cutting; thesewere excluded from the study.

METHODS

Historical forest inventory dataAll of the historical forest inventories within

our study area were conducted in 1911. Theinventories were conducted by two-personcrews, with one person compass and distancingand the other assessing the forest. Their assess-ments involved recording all live conifer trees�30.5 cm (12 inches) in diameter at breast height(dbh) within belt transects that were 20.1 m (66feet or 1 chain) wide and 402 m (1320 feet or 20chains) long. Trees were tallied by species intodbh classes of 5.1 cm (2 inches). Recording ofsmaller trees (,30.5 cm dbh) was inconsistentacross transects. In addition to inventorying treesthe following observations were made in eachtransect: rock type and exposure, soil texture,ground cover, and shrub cover. General notes onforest condition, including insect depredation,fire damage, stand development stage, and thespatial distribution of the trees were also record-ed.

Transect locations were based systematically

on the Public Land Survey System (PLSS), whichwas the primary method used to survey rural orundeveloped land in the western US. Transectsstarted and ended at the mid-points of quarter-quarter sections, which we refer to as lots, withone belt transect sampled in each 15.7 ha (40acres) lot for the area surveyed. Transects wereplaced as strips across a section (an areacomprised of 16 lots) and generally orientedeither N-S or E-W, against dominant contourwithin a section. Some transects were placed for10 chains in a N-S direction followed by 10 chainsin an E-W direction allowing surveyors toconnect strips within a section. Each transectcovered 0.9 ha (2 acres).

We assembled a suite of variables to charac-terize forest structure and composition using treelists generated from the 1911 belt transect data.The tree lists were standardized for area sampledsuch that outputs represented per hectare values.The constructed variables were: tree density forall trees and partitioned into three dbh classes,proportion of stand basal area by three speciesgroups, and total basal area. Basal area is thetotal cross-sectional area of all live tree stems in astand (similar basal area can be produced by afew large trees or many small trees). The threedbh classes used to report partitioned treedensity were: 30.5–61.0 cm, 61.1–91.4 cm, .91.4cm, and were based on a stand classificationscheme used in forest management throughoutthe Sierra Nevada (USDA 2004) and in previouswork (Lutz et al. 2009, Collins et al. 2011). Thespecies groups that we investigated for potentialchanges in proportion of stand basal area were:(1) pine—ponderosa pine and sugar pine, (2) truefir—white fir and red fir (Abies magnifica), and (3)incense-cedar.

In addition to recording information on foreststructure and site characteristics, during thesurveys the field crew took detailed notes onvegetation conditions along transects (see Ap-pendix for a copy of all notes recorded duringthis inventory); these records were used toestimate the incidence of high severity fire.Surveyors typically noted where they enteredand exited patches of contrasting vegetation,such as chaparral or dense ‘‘immature’’ timber,but did not record explicit descriptions of fireseverity in terms of damage to timber; weassumed these areas were burned by high

severity fire. We used the length of these discreteforest patches along survey transects to estimatethe proportion of high severity fire on thelandscape (average proportion of transect in highseverity patch multiplied by percentage of totaltransects with evidence suggesting high severityfire).

The presence of chaparral in these forests canbe both a successional change brought about byhigh severity fire (Kauffman and Martin 1991) orit can be a product of edaphic conditions thatlimit tree establishment/growth (e.g., dry siteswith shallow soils) (Nagel and Taylor 2005).Given the uncertainty as to what was driving theobserved chaparral, we bracketed our estimatesof high severity fire. We noted transects in whichobserved chaparral may have been environmen-tally and/or edaphically controlled (see Appen-dix). These included transects at the edge of thetimber survey area, which corresponded with theextent of the timber belt, as well as transects thathad distinct topographic features, such as a ridgetops or steep canyons. Our bracketed highseverity fire estimates included and excludedthese potentially environmentally and/or edaph-ically controlled transects. In all cases the highseverity patches were smaller than the length ofthe transect, or did not result in completemortality across a transect, because all transectscontained trees .61 cm dbh.

Current forest inventory dataThe Forest Inventory and Analysis (FIA)

program provides a nationwide inventory offorestlands in the US and is executed by theUSFS. The FIA program delivers inventory andmonitoring data related to forest structure,composition, and health, based on a set ofsystematically randomized plots across the coun-try. Standard FIA plot densities are one plot per2428 ha (6000 ac). FIA plots (673 m2) are dividedinto four 7.3 m (24 ft) radius circular subplots,with one central subplot and three peripheralsubplots arranged at 120-degree angles from plotcenter. Peripheral subplots are situated at adistance of 36.6 m (120 ft) from the subplotcenter to the plot center. For all subplots, everytree .12.7 cm (5 in) is measured (dbh, height)and identified to species. Each subplot alsocontains a 2.1 m (6.8 ft) radius circular microplotfor the measurement of tree regeneration (all

trees ,12.7 cm dbh, seedlings and saplings).More information pertaining to FIA protocol canbe found in Bechtold and Patterson (2005),Woudenberg et al. (2011), and the FIA programwebsite (http://www.fia.fs.fed.us/). All FIA plotdata used here was based on the most recent FIAprotocol.

Data analysisVegetation in the 1911 transects was summa-

rized by basal area, stem density of tallied trees,and shrub cover. Shrubs, as they were denotedby 1911 surveyors, included mountain misery(Chamaebatia foliolosa), manzanita (Arctostaphylosspp.), black oak, canyon live oak, scrub oak (Q.berberidifolia, or shrubby form of Q. kelloggii or Q.chrysolepis), chaparral, chinquapin (Chrysolepissempervirens), willow (Salix spp.), mountainmahogany (Cercocarpus betuloides), wild plum(Prunus spp.), and Sierra gooseberry (Ribesroezlii ). We converted qualitative assessments ofcover, assigning a cover of 10%, 20%, 50% or 90%for each species based on the descriptionprovided by the surveyor (e.g., sparse, scattered,moderate, and dense, respectively). It is worthnoting that for the entire 1911 area included inour analysis there were only two sets ofobservers; therefore, a reasonable assumption ofconsistency in the written descriptions across thesurvey area.

Topographic variables were derived using adigital elevation model (Gesch et al. 2002, Gesch2007). Raster datasets for slope, aspect, andcurvature were generated using Spatial Analysttools in ArcMap 10.1. Aspect was classified sothat values ranged from 0 (xeric) to 20 (mesic)(Parker 1982). Pixels were categorized by fourtopographic position index (TPI) classes (valleybottom, gentle slope, steep slope, ridgetop) usingthe CorridorDesigner toolbox (Majka et al. 2007).The default settings of the ‘‘create topographicposition raster’’ tool were used so that pixelelevation was assessed relative to neighboringpixels within 200 m, with those being lower orhigher by 12 m compared to the neighborhoodaverage classified as valley bottom or ridgetop,respectively. The cutoff point for gentle versussteep slope was 68 (10.5%).

A raster of topographic relative moisture index(TRMI) was calculated using TPI, aspect, slope,and curvature following the method of Parker

(1982). Actual evapotranspiration (AET) andannual climatic water deficit were calculatedusing soil water holding potential, temperature,and precipitation (Churchill et al. 2013). We usedthe soil water holding capacity in the top 150 cmof the soil (Soil Survey Staff 2013) and weatherdata from the period 1901–1910, obtained fromClimate WNA (Wang et al. 2011). All topograph-ic variables were calculated at a 10 m resolutionexcept AET and water deficit, which werecalculated at a 30 m resolution then resampledto a 10 m pixel size to match that of the othervariables. Mean transect values for continuoustopographic variables were extracted from 10-mraster layers using zonal statistics. For TPI,proportion of transect area in each class wascalculated, and a TPI class was assigned to eachtransect based on the majority area in each class.

Transects were classified into groups using k-means cluster analysis (Hartigan and Wong1979). Clustering was based on the followingoverstory and understory structure variables:cover of mountain misery, total cover of all othershrub species, basal area by tree species (yellowpine [ponderosa and Jeffrey pine], sugar pine,incense-cedar, white fir, and total), and stemdensity by size class (30.4–61, 61.1–91.4, .91.4cm dbh and total). Variables were z-scorestandardized prior to clustering to account fordifferences in scale (McCune and Grace 2002). Toselect the optimum number of clusters wecompared results for up to a 12 cluster solutionto 250 runs done using randomized input data.Graphs of the within-group sum of squared error(SSE) and the absolute difference in SSE from theaverage SSE of the randomized data wereexamined. The cluster solution that maximizedthe difference between sum of squared error forthe chosen cluster solution and the average of therandomized runs was selected (Peeples 2011).

To investigate whether identified vegetationgroups were associated with different topo-graphic characteristics we used a two-stageanalysis. First, we used a random forest analysisto identify which, if any, of the constructedtopographic variables explained the occurrenceof the vegetation groups. This was performed inR version 3.0.2, using the conditional inferencemethod ‘‘cforest’’ (Hothorn et al. 2006). Thismethod constructs a suite of conditional infer-ence trees, using a randomly selected subset of

predictor variables and a random subsample ofplots for each tree. Examining a large number oftrees allows for identification and ranking ofinfluential variables, and averages out the insta-bility of individual regression trees that canexhibit large changes in structure due to randomvariation in the data (Strobl et al. 2009). Variableimportance was assessed using the conditionalmethod developed by Strobl et al. (2008). Thesecond part of this analysis was to comparevalues for the top three topographic variables, asindicated by the variable importance rankingsfrom the random forest analysis, among thevegetation groups using an ANOVA model thataccounted for unequal variances. When ANOVAmodels were significant (a ¼ 0.05) a Games-Howell comparison was used to compare meansamong vegetation group (Games and Howell1976). This was performed using ‘‘proc MIXED’’in SAS version 9.4.

Following the cluster analysis, the ForestVegetation Simulator (FVS; Dixon 2002) wasused to estimate canopy cover for the historicalinventory transects. FVS uses tree species andsize to generate crown radii for all trees in agiven belt transect. FVS then calculates thepercentage of ground area directly covered withtree crowns, correcting for canopy overlap(Dixon 2002). To investigate how well FVScanopy cover estimates approximate field-basedobservations in old-growth forests, we comparedfield-measured canopy cover from an intactJeffrey pine-mixed forest in the Sierra San PedroMartir, Mexico (Stephens and Gill 2005), to FVS-estimated canopy cover for the same plots. Thiswas done for 25 0.1-ha circular plots, which wereestablished on a regular 125-m grid. Within eachplot the following information was collected foreach tree .1 cm dbh: status (live/dead), species,and dbh (to nearest 0.1 cm). Canopy cover wasassessed with GRS densitometer based on a 53 5grid, with approximately 3 m between gridpoints. The number of points that intersectedtree crowns was multiplied by four to obtainpercent canopy cover. The trees recorded on eachplot were entered into FVS to generate modeledestimates of canopy cover for comparison to fieldbased measurements.

FIA plot data was obtained from all west-sidemixed conifer and ponderosa pine forests on theSequoia and Sierra National Forests (data col-

lected from 2001 to 2008) to compare to the 1911forest structure data. The same forest structurevariables were computed for the FIA data asdescribed above for the 1911 historical data. Notethat we only included trees .30.5 cm dbh fromthe FIA data to match the minimum diameterused for the 1911 data. We tested for differencesin forest structure variables among time periods(1911 against recent FIA) using Welch’s variance-weighted one-way ANOVA, which does notrequire an underlying assumption of homogene-ity of variances (Welch 1951). This analysis wasdone with Proc GLM in SAS version 9.4.

RESULTS

Overall the 1911 dataset contained 18,052 treesin 378 transects, totaling just over 300 ha intransect area. Forest structure was highly vari-able in this forest. Total tree basal area rangedfrom 1 to 60 m2 ha�1 and tree density rangedfrom 2 to 170 ha�1 (based on trees .30 cm dbh).On average the basal area was comprised of 25%white fir, 29% incense-cedar, 8% sugar pine, and38% ponderosa pine. For each species, theproportion of transects in which it was absentwere: 18% (white fir), 19% (incense-cedar), 35%(sugar pine) and 8% (ponderosa pine). Stems 30–60 cm dbh were about twice as abundant onaverage as those in the 60–90 and .90 cm sizeclasses (Table 1). Shrubs (all species includingmountain misery) were found in 54.4% oftransects.

K-means cluster analysis divided transects intofour groups (Table 1). The first group, mixedconifer-high basal area (MC High BA) wascharacterized by high total tree basal area andstem density, with high basal area of white fir,incense-cedar, and sugar pine but low ponderosapine basal area and density. This group account-ed for 15% of the total survey area. White fir andincense-cedar were the dominant species in thisgroup and mountain misery was entirely absent.The second group was mixed conifer-averagebasal area (MC Ave BA) and had values close tothe overall averages for all forest structurevariables in the sampled landscape, and account-ed for 34% of the total area. Incense-cedar hadthe highest tree basal area, but white fir andponderosa pine were also co-dominant (based ontree basal area). The third group, mixed conifer-average basal area-high shrubs (MC Ave BAShrubs) had very high cover of mountain miseryand other shrubs, above average density of trees,91.4 cm dbh, and high basal area of pinespecies, particularly ponderosa pine. This groupaccounted for 10% of the 1911 survey area. Thetwo species with the greatest overall tree basalarea in this group were ponderosa pine andincense-cedar. The last group, which accountedfor the largest percentage of area (41%), wasdominated by ponderosa pine (Pond Pine) andhad low conifer density, and tended to havelower than average tree basal area of all speciesexcept ponderosa pine. K-means groups tendedto be spatially clustered within the study area

Density of trees .91 cm dbh was the highest inMC High BA and basal area was approximately42 m2 ha�1. The two MC classes with averagebasal areas (MC Ave BA, MC Ave BA Shrubs)differed by understory shrub cover (26% versus76%) and the dominance of mountain misery (5%versus 62%), respectively. Interestingly the aver-age mixed conifer areas with high shrubs wereprimarily located in the northern and north-eastern portions of the study area (Fig. 3). Theshrub dominated areas had a higher proportion

of ponderosa pine that was co-dominated byincense-cedar; the areas with lower shrub coverwere dominated incense-cedar with a co-domi-nance of white fir (Table 1). Tree density in the30–61 cm dbh class was twice as large in the MCAve BA Shrub group when compared to the MCAve BA group even though average total basalareas were very similar.

longer in the case of transects consisting ofimmature timber) was low and varied from 1%to 3% in mixed conifer forests and from 4% to 6%in ponderosa pine forests (Table 4). Insects thatwere causing some tree morality were recordedin 30–45% of Pond Pine, MC High BA, and MCAve BA structural groups; this increased to 87%in the MC Ave BA Shrubs group (Table 3).

Tree regeneration was recorded as ‘‘none’’,‘‘scarce’’, or ‘‘low’’ in approximately 40% of thePond Pine, MC High BA, and MC Ave BAstructural groups; this increased to 92% in theMC Ave BA Shrubs group. Conversely, approx-imately 20% of the MC Ave BA and Pond Pinegroups had ‘‘high’’ conifer tree regeneration(Table 3). Oaks were present in many plots, withfewer in the MC Ave BA Shrubs and MC HighBA structural groups (Table 3). Tree distributionswithin the belt transects were diverse withapproximately one-third of MC Ave BA, MCAve BA Shrubs, and Pond Pine structural groupshaving a ‘‘scattered’’ distribution (Table 3). PondPine forests were noted for their openness andMC High BA areas for their high density (41% oftransects). Trees were recorded as ‘‘distributed ingroups’’ in 26% of the MC Ave BA Shrubsstructural group with MC High BA having thefewest groups (2.6%) (Table 3). Approximately20% of the transects in MC High BA, MC Ave

BA, and Pond Pine structural groups had a‘‘patchy’’ forest distribution with ‘‘uniform’’forests most common in the MC High BA group(23%); in the other forests groups ‘‘uniform’’forests were relatively rare (Table 3).

The average difference between SSPM plot-measured and FVS-estimated canopy cover isreported in Table 5. Both the average overalldifference, which includes positive and negativevalues, and the average absolute difference,which only includes absolute values of thedifferences are reported. Average canopy coverestimates projected by FVS were slightly belowthat measured in reference forests (24.8% vs.26.1%, Table 5). However, a paired t-test on thetwo canopy cover estimates indicated no signif-icant difference (P ¼ 0.57) suggesting that ourFVS estimates of canopy cover are accurate. It isworth noting that both the plot-based and FVS-projected canopy cover estimates agree with apreviously reported canopy cover estimate(25.3%) from a larger sampling area in the sameforest of northern Baja California, Mexico, whichwas based on ten 100 m canopy line intercepttransects (Stephens and Gill 2005).

Tree density increased markedly between 1911and the recent sampling effort (FIA plots),especially in ponderosa pine forests (430%increase) (Table 6). This increase was highly

Large trees (.91.4cm) decreased by 50% in mixed conifer forestsand by 70% in ponderosa pine forests whencomparing current structure to that in 1911(Table 6). Total tree basal area in mixed coniferforests was unchanged between 1911 and thepresent (approximately 30 m2 ha�1) but increasedby approximately 50% in ponderosa pine forests(Table 6). Sugar pine basal area remainedrelatively constant in mixed conifer forestswhereas incense-cedar basal area was two timesgreater in 1911 as compared to today. White firbasal area in mixed conifer forests increasedgreatly in the recent measurement versus 1911.Average forest canopy cover increased from 25%to 49% in mixed conifer forests and from 12% to49% in ponderosa pine forests; canopy cover incurrent forests is similar between types versus in1911 when mixed conifer forests had twice thecanopy cover as ponderosa pine forests.

DISCUSSION

The southern Sierra Nevada ponderosa pineand mixed conifer forests sampled in 1911 hadlow tree densities but there was importantvariation by structural groups (Table 1). ThePond Pine forest group tended to be located in

the lower elevation portion of the study area andhad the lowest tree densities and basal areas (25trees ha�1 and 11 m2 ha�1, respectively). Ponder-osa pine made up 58% of tree basal area in 1911followed by approximately equal amounts ofwhite fir and incense-cedar (18% each). Shrubcover was important in this group and averaged14% with less than one-tenth being mountainmisery.

In Jeffrey pine dominated mixed conifer forestsin the Sierra San Pedro Martir, Mexico, whichhave not experienced wide-spread fire suppres-sion or harvesting, average tree basal area was 20m2 ha�1 (Stephens and Gill 2005) and this islarger than that found in 1911 ponderosa pineforests in the southern Sierra Nevada. Jeffreypine dominated the SSPM forests contributing67% of basal area followed by smaller amounts ofwhite fir and sugar pine (23% and 8% of basalarea, respectively). In ponderosa pine forests innorthern Arizona, Fule et al. (2009) found thatponderosa pine dominated stand basal area(64%) in 1870 but contributed only 36% in thesame forest in 2003 after fire exclusion andharvesting.

from ponderosa pine and mixed conifer forestsfrom studies that varied in spatial scale (1–1000ha) and reference date (1860–1952). Selectingponderosa pine studies that provided informa-tion from larger areas (.80 ha) and estimatedstructural characteristics before the major im-pacts of Euro-Americans (before 1880) resulted ina basal area 10.4 m2 ha�1 which is similar to thesouthern Sierra Nevada forests studied here.Stoddard (2011) also summarized pre Euro-American mixed conifer forest basal area of 16.2m2 ha�1, which is lower than all three mixedconifer structural groups in the southern SierraNevada (Table 1), probably reflecting lowerecosystem productivity in the Southwestern US.Reynolds et al. (2013) provided another recentreview of historical forest conditions from theSouthwestern US and report ponderosa pine andmixed conifer tree density and basal area of 30–315 trees ha�1 and 5–20 m2 ha�1, and 53–251 treesha�1 and 9–28 m2 ha�1, respectively. The valuesfrom Reynolds et al. (2013) overlap those foundin our 1911 data, but the basal areas from our1911 estimates in the southern Sierra Nevada areat the high end of their distributions, especiallyfor mixed conifer forests.

The description of forest conditions in 1911support previous assertions on the critical role offire in these ecosystems (Kilgore and Taylor 1979,Skinner and Chang 1996, Scholl and Taylor 2010).Past fire evidence was clearly seen in approxi-mately 95% of all mixed conifer structural groupsand on 80% of ponderosa pine areas (Table 3).The vast majority of fire evidence was describedas low to moderate damage (Table 3) with lowpercentages of high severity fire on this land-scape (1–6%) (Table 4). Another piece of evi-dence of landscape-scale dominance of low-moderate severity fire is the ubiquity of largetrees in all of the sampled transects (Table 1). Thisindicates that these trees persisted for a longperiod of time (200–400 years) without experi-encing a stand-replacing disturbance. Comparingforest inventory data from 1911 to the present(Table 6) indicates that current forests havechanged greatly, particularly in tree density,canopy cover, density of large trees, dominanceof white fir in mixed conifer forests, and thesimilarity of tree basal area in contemporaryponderosa pine and mixed conifer forests. Thevast majority of published studies on historic

mixed-conifer forests document lower tree den-sities and a more open structure comprised of ahigher proportion of old and large trees that weremore spatially heterogeneous (having gaps andpatches of trees) and more uneven-aged com-pared to current conditions (Fule et al. 2002,2009, Moore et al. 2004, Stephens and Gill 2005,North et al. 2009, Collins et al. 2011).

Topography also influenced the historicaldistribution of vegetation in our study area.Ponderosa pine forests were associated withlower elevation, more southwesterly aspects,and greater values of AET. The influence ofelevation on vegetation type, with ponderosapine forests occurring below mixed coniferforests, has long been recognized (Show andKotok 1929) and the association of greater pinedominance with more southerly aspects has alsobeen observed (Fites-Kaufman et al. 2007, Ly-dersen and North 2012). However the associationwith AET was unexpected, as others have foundthis variable to be associated with greaterproductivity (Stephenson 1998; Kane et al., inpress). The southern portion of the study area,which was predominantly ponderosa pine forest(Fig. 3) had higher water holding capacity,leading to greater values of AET. While waterholding capacity and AET were relatively lowerin the rest of the study area, perhaps the treesmay be able to access deeper water stores inweathered bedrock (Meyer et al. 2007) allowingthese areas to sustain more productive foresttypes.

One important artifact is the scale at which the1911 data were recorded (0.9 ha transect area)such that any fine-scale patterning cannot bediscerned (Hagmann et al. 2013). The majority ofthe variability in structure in frequent-fire forestshas been observed at spatial scales smaller than0.4 ha (Larson and Churchill 2012, Fry et al.2014), and topographic characteristics that influ-ence forest structure may also be observed at asmaller scale (Lydersen and North 2012). Thescale at which the 1911 inventory data wererecorded homogenizes this patchiness, which hasbeen shown to include widely spaced individu-als, clusters of large trees, dense patches ofregeneration, and small openings (North et al.2002, Franklin and Van Pelt 2004, Larson andChurchill 2012, Lydersen et al. 2013, Fry et al.2014). This fine-scale patchiness, and the scale at

which topography affects forest patterns, areimportant characteristics that warrant furtherinvestigation.

The fact that the southern Sierra forests westudied were more open historically relative tocurrent conditions is not surprising given thenumber of previous studies that have alreadydemonstrated this trend (e.g., Parsons andDebenedetti 1979, Scholl and Taylor 2010). Whatis more surprising is just how open these forestswere in 1911, with average canopy cover being25% and 12% in mixed-conifer and ponderosapine types, respectively (Table 6). Fornwalt et al.(2002) modeled ponderosa pine reference canopycover conditions of 13–22% on the ColoradoFront Range and canopy cover in unmanagedJeffrey pine-mixed conifer forests in northernBaja California, Mexico, was 27% (Stephens et al.2007b). In addition, other canopy cover studiesincluding White (1985), Covington and Sackett(1986), and Covington et al. (1997) reported21.9%, 19.0%, and 17.3% canopy cover forponderosa pine reference conditions on the FortValley Experimental Forest, Arizona, respectively(Reynolds et al. 2013); these values are similar tocanopy cover estimates from southern SierraNevada ponderosa pine forests in 1911 (Table 1).

The 1911 forest inventory data depict a forestwith high heterogeneity (Tables 1 and 3). Assuch, the historical data we present do notsupport the idea of basing management goalsfor restoration and forest resilience treatments onaverage values (Stephens and Gill 2005, North etal. 2009). Perhaps the ranges documented in thiswork in canopy cover and tree densities by sizeclasses can assist in the creation of restorationplans to increase forest resilience (Collins et al.2011). The second point related to the historicaldistributions found here is that common restora-tion goals of mixed conifer and ponderosa pineforests, particularly canopy cover and treedensity, are on the upper end of or entirelyexceed the values we report based on the 1911data (Table 1). Consequently, forest restorationgoals in southern Sierra Nevada mixed coniferand ponderosa pine forests are probably mis-aligned with the historic range of variation instand structure. We note that our analysis is atthe landscape scale, which may not capture finerscale heterogeneity brought about by openingsand denser forest patches, however our estimates

of landscape conditions are robust.

Relevance to dry forest managementThe 1911 forest inventory data describes a

forest that is a product of a range of fire effectsover a long period of time (i.e., a functioning fireregime), as well as the underlying topographic/moisture availability influence. The changes inforest structure and composition relative to 1911indicate severely altered present forest condi-tions. The present forest in the western portionsof Sequoia and Sierra National Forests is charac-terized by much higher overall tree densities,shifted species dominance from pine to fir(especially in mixed conifer forests), lowerdensity of large trees, and higher canopy cover.These findings are consistent with those fromprevious studies in the Sierra Nevada (Parsonsand Debenedetti 1979, Ansley and Battles 1998,North et al. 2007, Scholl and Taylor 2010, Collinset al. 2011, Knapp et al. 2013, Dolanc et al. 2014).

Periods of frequent fire in mixed-conifer andpine-dominated forests gave fire-resistant speciesa competitive advantage, allowing them toestablish dominance (Stephens et al. 2008).During ‘‘fire-free’’ or less frequent-fire periods,pines persisted due to their dominant positionsin the forest canopy (Fule et al. 2009). However,extensive fire-free periods, such as that associat-ed with fire exclusion, coupled with grazing,selective logging, and favorable climatic condi-tions for young tree establishment in the early20th century has created atypical stand compo-sitions and structures in many of today’s SierraNevada ponderosa pine and mixed-conifer for-ests. In many locations, large, dominant ponder-osa pine trees have been significantly reducedleaving today’s stands dominated by small trees.This has also been documented in other studiesin mixed-conifer and ponderosa pine forests inthe western US (Swetnam and Baisan 2003,Moore et al. 2004, North et al. 2009).

Recently a new procedure has been used toestimate past forest structure based on theestablishment of a public land survey system(PLSS) by the General Land Office (GLO), theadvantage of this dataset is it covers most of thewestern US. Baker (2012, 2014) used this system(GLO), which used eight trees per section (259ha) that were marked to assist in the relocation ofsurvey section corners, to reconstruct historical

forest conditions in eastern Oregon and the SierraNevada. Four townships (or 144 sections) ineastern Oregon (Baker 2012) overlap an area thatused similar historical transect data analyzed inthis work (Hagmann et al. 2013). GLO surveydata collected in 1866–1895 would include arecord of approximately 1152 trees markingsection and quarter section corners in this fourtownship area while the historical timber transectinventory included 163,558 trees on 1355 tran-sects (Hagmann et al. 2013). More recently Baker(2014) used similar GLO procedures to estimatepast forest structure and fire severity in the SierraNevada. A comparison of the results from theGLO procedures to four different study sitesfrom northern Oregon to the southern SierraNevada demonstrates that the GLO methodsoverestimate historic tree density (Table 7). Onechallenge in the comparison of these results ispossible differences in lower diameter limits inthese studies. The transect studies (Collins et al.2011, Hagmann et al. 2013, 2014, this work) allhave explicit lower diameter limits whereas theGLO reconstructions do not include this infor-

mation (Table 7). One study that also comparedthese two methods determined that the largedifferences in tree densities between the directinventory and GLO could not be reconciled bypossible differences in diameter limits of the twodatasets (Hagmann et al. 2013). Another limita-tion of all historical datasets is they are from onebrief time period which characterizes past fireregimes with limited temporal depth.

Our estimate of past mixed conifer andponderosa pine high severity fire (1–6%), whichare similar to estimates from other work (Ste-phens et al. 2007a, Mallek et al. 2013), are muchlower than those reported by Baker (2014) for theSierra Nevada (31–39%). Perhaps informationfrom contemporary restored fire regimes, forwhich fire severity patterns can be quantifiedmore robustly, can provide insight. Working inmesic upper-elevation mixed conifer forests inthe Sierra Nevada that have been burnedrepeatedly by lighting fires, Collins and Stephens(2010) found that high severity fire accounted for15% of the total burned area in recent large fires.These fires occurred 30 years after the start of the

natural fire program in this area, suggesting arelatively intact fire regime. However, despitehaving an intact modern fire regime, this areapreviously experienced nearly 100 years of fireexclusion, which corresponded with a largeincrease in tree establishment (Collins andStephens 2007). It is reasonable to assume thislarge pulse of tree establishment led to higherlevels of severe fire than occurred historically.Furthermore, the higher elevation and associatedshifts in species composition (high dominance ofred/white fir and lodgepole pine [Pinus contortasub. murrayana]) may also contribute to thegreater proportion of high severity fire reportedby Collins and Stephens (2010). Collectively,these points suggest that 15% high severity fireis likely an overestimate for historical highseverity proportions in ponderosa pine-mixedconifer forests, indicating that our 1–6% esti-mates are likely closer to actual conditions thanthe 31–39% posed by Baker (2014).

Changing climates are already warming tem-peratures in the Sierra Nevada so a specific goalto recreate past conditions is not advisable(Stephens et al. 2010). However, the informationfrom this work could be used to inform theproduction of desired landscape conditionsbecause the forests sampled in 1911 were highlyresilient to many of the same environmentalprocesses affecting today’s forest ecosystems,including insects, diseases, and fire. Increasingforest resiliency is the most common goal thatforest mangers desire in a world of changingclimates (Fule 2008, Stephens et al. 2010) and thiswork could be used to inform this goal.

Fig. A1. Importance ranking of the topographic variables based on their association with vegetation class of

historical survey transects, as determined by random forest analysis. Variables included in the analysis were

actual evapotranspiration (AET), elevation, transformed aspect, water deficit, topographic relative moisture

index (TRMI), slope steepness, and proportion of transect area in each of the four topographic position index

categories (% Steep Slope, % Ridgetop, % Valley Bottom and % Gentle Slope). The three variables that appear in

Table 2 (AET, elevation, aspect) are the three most highly ranked variables.
