EXECUTIVE SUMMARY Terrestrial gastropods of southeastern British Columbia are poorly known but contain numerous species of conservation interest. Distributions of additional species found in northern Idaho and northwestern Montana may also extend to British Columbia. In July and September 2007, we surveyed 63 sites in southeastern British Columbia, focusing on habitats for species listed as being at risk federally or provincially. The sampling sites were mainly on BC crown lands and distributed among five biogeoclimatic zones (ICH, MS, IDF, ESSF, PP) and six broad habitat categories (upland coniferous forest, riparian coniferous forest, sub-alpine coniferous forest, riparian cottonwood-deciduous forest, upland deciduous forest, rocky slope). Most of the sampling effort was in the ICH and MS biogeoclimatic zones and within riparian deciduous or coniferous forest and in upland coniferous forest.

In total, we detected 32 species of terrestrial gastropods, including five species of introduced slugs. We found five provincially listed species: Pale Jumping-slug (Hemphillia camelus) at six sites, Magnum Mantleslug (Magnipelta mycophaga) at one site, Rocky Mountainsnail (Oreohelix strigosa) at 23 sites, Subalpine Mountainsnail (O. subrudis) at one site, Banded Tigersnail (Anguispira kochi) at five sites, and Coeur d'Alene Oregonian (Cryptomastix mullani) at one site. In addition, we found the Pygmy Slug (Kootenaia burkei) at two sites, representing first records of the species in Canada.

The Rocky Mountainsnail (blue-list; G5, S3S4) was widely distributed within the study area and was most abundant in lower elevation riparian, cottonwood-dominated floodplain habitats. These locality records are within the known general range of the species but add many new locations, especially in the East Kootenay region. We found the Subalpine Mountainsnail (blue-list; G5, S3S4) only at one location but surveyed just four sites in subalpine habitats. There is much variability in shell shape, proportions and size, and unique populations, ecotypes, or even new species of both species of mountainsnails may exist in British Columbia.

Of particular conservation interest are the Magnum Mantleslug (G3, S2S3) and the Pygmy Slug (G2; unrated in BC) because of their high global ratings and few known occurrences in British Columbia. We found the Magnum Mantleslug within the splash zone of a creek in subalpine habitat south of Mt. Fernie. This record represents the easternmost locality for the species in the province. We found the Pygmy Slug in moist riparian forest at two sites about 100 km apart, east and west of Creston.

Further surveys are needed to delineate the distribution of the Magnum Mantleslug, Pygmy Slug, and other species of conservation interest more accurately. We also recommend more extensive surveys of rocky slopes and subalpine habitats, which in adjacent areas in Montana and Idaho harbour interesting faunas and unique populations of gastropods.

1.0 INTRODUCTION Terrestrial gastropods (slugs and snails) of many areas of British Columbia are poorly known but contain species of conservation interest. Much of past survey effort has focused on Vancouver Island and the Lower Fraser River valley, whereas most other parts of the province have received little attention. The Columbia River Drainage in the southeast is of particular interest, as it contains several unique species to the province, such as the Rocky Mountainsnail (Oreohelix strigosa) and the Magnum Mantleslug (Magnipelta mycophaga). Several additional species of conservation interest occur in northern Idaho and Montana and may also occur in southeastern British Columbia. These species include the Marbled Jumping-slug (Hemphillia danielsi), Sheathed Slug (Zacoleus idahoensis), Papillose Taildropper (Prophysaon dubium), Blue-grey Taildropper (P. coeruleum – inland clade), and Pygmy Slug (Kootenaia burkei).

Forsyth (1999) provided a summary of terrestrial gastropods reported from the Columbia Basin in British Columbia. He found only four brief accounts that specifically mentioned records for the Columbia Basin (Whiteaves 1905, Vanatta 1906, Berry 1922, Carl and Hardy 1945). The monograph by Pilsbry (1939-1948) of North American terrestrial molluscs also contains some records for the area. Recent work includes surveys by the Royal British Columbia Museum in September 1998 as part of the Living Landscape project and personal collections by Robert and Tammy Forsyth and by Heike Reise and John Hutchinson in the late 1990s. These collections resulted in the addition of 11 native and 5 introduced species to the list of species known from the area (Forsyth 1999). Much of the Columbia Basin and Kootenay Mountains remain to be surveyed. Surveys are needed to delineate distributions and habitat needs of species at risk, assess their status more accurately, and develop conservation strategies.

Here we report the results of surveys for terrestrial gastropods conducted in July and September 2007 within the Kootenay region (east of Nelson and south of Invermere) of southeastern British Columbia. The focus was species suspected to be rare or at risk. We also document the occurrence of the Pygmy Slug for the first time in Canada.

2.0 OBJECTIVES The objectives were to obtain information on distributions and habitats of terrestrial gastropods deemed to be at risk either provincially or nationally (Table 1). These species include the Coeur d'Alene Oregonian, Pale Jumping-slug, Banded Tigersnail, and Rocky Mountainsnail. The surveys targeted potential habitats of these species, as well as habitats of previously unreported gastropods of conservation interest known from adjacent areas in the United States (Table 1).

3.0 STUDY AREA We surveyed 63 sites for gastropods in 2007, attempting to spread the survey effort widely within the Kootenay region of southeastern British Columbia and targeting habitats for species at risk (see Appendix A for location and description of the sites). The sites were located in an area bounded by Nelson in the west, BC-Alberta border in the east, Canada-USA border in the south, and Invermere in the north (Fig. 1). The surveys focused on the Rocky Mountain trench, the west slope of the Rocky Mountains, and areas close to the Idaho and Montana border.

Most sites were located on provincial Crown lands subject to forestry, mining, recreation, and ranching. Species at risk on provincial Crown lands can potentially receive protection through the Identified Wildlife Management Strategy under the Forest and Rangeland Protection Act. To increase habitats sampled, several sites were located on private land especially in low elevation, valley bottoms that tend to be productive sites for a diversity of terrestrial gastropods. Most private lands in the Kootenay region are in low elevation valley bottoms and in coal mining areas along the west slope of the Rocky Mountains.

A wide variety of habitats were sampled to maximize the diversity of gastropod species found. Sites were located in all biogeoclimatic (BEC) zones in the Kootenay region except the Alpine Tundra. The main Biogeoclimatic zones sampled were the Interior Cedar-Hemlock (ICH; n = 20 sites), Montane Spruce (MS; n = 18), Interior Douglas-fir (IDF; n = 13), Engelmann Spruce-Sub-alpine fir (ESSF; n = 10), and Ponderosa Pine (PP; n = 2) biogeoclimatic zones. The sites ranged in elevation from 538 to1704 m asl, and averaged 1158 m (Appendix A).

We divided the sampling sites into six broad habitat categories based on vegetation composition and structure, terrain, and elevation (Table 2). The habitat at most sites was dominated by coniferous forest (57% of sites), compared to deciduous forest (32%), and rocky slope (11%). Most sites (56%) were located in riparian habitats because these areas were productive and moist and therefore tended to have the most diverse assemblages of gastropods.

Table 2. Habitats sampled for gastropods in 2007. Habitat type Number of sites (%) Upland coniferous forest 15 (23.8%) Riparian coniferous forest 17 (27.0%) Sub-alpine coniferous forest 4 (6.3%) Riparian cottonwood-deciduous forest 18 (28.6%) Upland deciduous forest 2 (3.2%) Rocky slope 7 (11.1%)

Upland Coniferous Forest This habitat is dominated by moist, relatively dense coniferous forest. The dominant tree species vary according to elevation and biogeoclimatic zone. Western redcedar and western hemlock dominate in moist regions, especially in the West Kootenays, and Engelmann spruce, subalpine fir, and western redcedar are common at higher elevations, in the East Kootenays. Douglas-fir, lodgepole pine, and ponderosa pine are dominant in drier sites, especially at lower elevations. The understory is usually dense with a moist forest floor consisting of needles, moss and abundant coarse woody debris.

Riparian Coniferous Forest This habitat tends to be more productive and moist than upland coniferous forest and contains a greater diversity of plants in the understory. Engelmann spruce is especially common.

Subalpine Coniferous Forest Subalpine forest consists of patches of Engelmann spruce and subalpine fir interspersed with abundant shrubs, herbaceous meadows, and rock outcrops. The four subalpine sites sampled occur at high elevations (1475-1704 m asl) and are subject to extreme climatic conditions. The growing season is short and the ground is snow covered most of the year. During mid-summer, the open subalpine slopes are often subjected to dry, windy conditions with moisture limited mainly to seepage areas and creeks.

Riparian Cottonwood-Deciduous Forest In the Kootenay region, cottonwood stands are confined mainly to lower elevations, especially within the wide floodplains of medium to large rivers. Deciduous riparian forest tends to be highly productive and moist compared to surrounding upland areas. Cottonwoods usually dominate the canopy along with trembling aspen and birch and with a minor component of western redcedar, Engelmann spruce and Douglas-fir. The understory contains a diversity of shrubs and herbaceous plants such as red-osier dogwood, snowberry, thimbleberry, willow, and Douglas maple.

Upland Deciduous Forest This habitat occurs on drier, south-facing valley slopes at lower elevations and consists of aspen, cottonwood, and birch stands. The shrub-layer is relatively dense and often contains saskatoon, rose, and Douglas maple.

Rocky Slope This habitat occurs on steep slopes and contains loose cobbles, gravel, and rock. The seven sites in this habitat are in rockslides, avalanche chutes, and talus slopes at various elevations. The tree canopy is open and usually consists of patches of small coniferous trees. The sparse understory consists of shrubs such as juniper, soopolallie, rose, saskatoon, and small clumps of herbs and grasses. The habitat is very dry, although the spaces between rocks and seepage areas provide moist refuges for gastropods.

4.0 METHODS

4.1 Survey methods The survey methods were modified from protocols developed for detecting rare species of terrestrial gastropods in the United States under the Northwest Forest Plan (Duncan et al. 2003). The objective was to produce “presence/not detected” type of data. The

surveys consisted of observers walking through the habitat of interest examining key microhabitat features for the target species. Key features included decaying logs, piles of bark, stumps, rocks, or other cover-objects or moist refuges, and accumulations of moist leaf litter.

At each site, we recorded geo-position with a Garmin IQUE 3600 handheld GPS unit (NAD 23). We also recorded the dominant vegetation, percentage coverage by the canopy and understory layers and by coarse woody debris, and the type of substrate within a ca. 20 m-radius plot, placed in a representative area of the habitat surveyed.

4.2 Search effort The surveys were conducted during two periods in 2007: 10 – 16 July and 22 – 27 September (see Appendix B for details of survey dates and conditions). We spent a total of 66.1 person-hours intensively searching for gastropods at 63 sites. The time spent at particular sites ranged from 20 to 140 person-minutes; the average survey time was 61 person-minutes per site. There was generally one visit per site, but one site was visited both in July and September.

The survey effort was distributed among five BEC zones and six broad habitats (Table 3). Most effort was directed towards riparian habitats, including coniferous forest along rivers and streams and cottonwood floodplains, because these moist habitats were more productive for gastropods than drier, upland habitats.

4.3 Identification of specimens and data recording Identification of gastropods was based on descriptions in Forsyth (2004) and Pilsbry (1939 – 1948). Nomenclature for scientific and common names follows Forsyth (2004). Identification was conducted in the field based on external characteristics; we did not dissect specimens. For each gastropod found, we recorded the following information: species, live or dead (snails), and microhabitat where found (see Appendix C for raw data of all gastropods detected). We took photographs of each target species found. To provide a permanent record, we collected vouchers of most species, using empty snail shells whenever possible. The vouchers are in the personal collection of the authors; selected specimens were deposited in the Royal British Columbia Museum, Victoria, BC.

5.0 RESULTS AND DISCUSSION

5.1 Overview of gastropods found In total, we detected 32 species of terrestrial gastropods, consisting of ten species of slugs and 22 species of snails (Table 4). Five of the slugs were introduced species. Across all sites, the small snail Brown Hive was encountered most frequently, at 54% of the sites surveyed. The Rocky Mountainsnail, Idaho Forestsnail, Forest Disc, Spruce Snail, and Gloss species were also frequently encountered, each occurring at over 20% of the sites (Fig. 2). We found five species on the provincial blue list of species at risk: Pale Jumping-slug, Magnum Mantleslug, Rocky Mountainsnail, Subalpine Mountainsnail, Banded Tigersnail, and Coeur d'Alene Oregonian. In addition, we found the Pygmy Slug at two sites, representing first records of the species in Canada (see next section for details). Raw data of all gastropods found during the surveys are in Appendix C.

In terms of numbers of species, rocky slopes and subalpine habitats appeared to be depauperate when compared to upland and riparian forested habitats (Table 5). Introduced slugs were found most frequently in riparian habitats, which often were disturbed and showed signs of human and/or livestock activity.

5.2 Species potentially at risk Mountainsnails (Oreohelix strigosa and O. subrudis; blue-list; G5, S3S4) Mountainsnails are large snails (shell width up to about 26 mm) with a pale, banded shell. Two species are known from BC and have been found only in the Columbia Basin area: Rocky Mountainsnail (Oreohelix strigosa) and Subalpine Mountainsnail (O. subrudis) (Forsyth 1999, 2004). Patterns of their distribution and abundance are poorly known, hindering accurate status assessment. Other undescribed species or unique populations of mountainsnails may exist. Shell size, proportions, texture, and colour are important features used in distinguishing species and subspecies of mountainsnails (Forsyth 2004). High variability in shell characteristics within populations and among age-size classes makes identification in the field difficult. Forsyth (2004) noted that the genus has not been adequately studied in British Columbia. In western United States, several undescribed species of Oreohelix are distinguished, some of which have very restricted distributions and are of conservation interest (Frest and Johannes 1993, 1995, Oregon Bureau of Land Management 1999, Montana Government, undated).

We found mountainsnails at 24 of the 63 sites surveyed (Table 6). These sites were located in the west Kootenays from Porthill, south of Creston, north to Lardeau River and in the east Kootenays from the BC-Montana border in the Flathead River Valley north to Bull River area (Fig. 3). The sites are within the known general range of mountainsnails in BC but add many new locations, especially in the east Kootenays from where only a few previous records existed (Forsyth 1999). We assigned snails from 23 sites to the Rocky Mountainsnail and those from one site to the Subalpine Mountainsnail, based on the high spire of all specimens from the latter site (shell width to height ratio 7.9 for the Subalpine Mountainsnail versus usually below 7.5 for the Rocky Mountainsnail in this study). The locality for the Subalpine Mountainsnail was on an unnamed mountain, about 6.5 km south of Mt. Fernie.

We found the Rocky Mountainsnail in all BEC zones surveyed, except in the Ponderosa Pine zone and in all habitats except the subalpine coniferous forest (Table 7). However, the species was unevenly distributed within sites among the BEC zones where it occurred (x2 = 8.705, df = 3, P < 0.01) and was most frequently found in the ICH and MS zones (Fig. 4A). The sites with the Rocky Mountainsnail were also unequally distributed among the habitats categories (x2 = 15.193, df = 3, P < 0.01; upland and riparian deciduous habitats combined), and the snails were most frequently found within mainly deciduous forest (Fig 4B).

Habitats of the Rocky Mountainsnail have been described as vegetated rockslides and talus slopes on dry mountainsides (Forsyth 1999, 2004 and references therein). Although we located the species in such habitats, we found it to be much more frequently encountered and abundant in lower elevation deciduous forests, particularly in cottonwood dominated floodplains. In these habitats the ground was often littered with empty shells of mountainsnails, as well as live snails, suggesting that densities were very high. These productive sites ranged from extensive cottonwood stands containing ancient trees to narrow riparian fringes with relatively young trees. Some sites had limestone outcrops, which probably satisfied high calcium needs of these and other large snails, allowing them to reach high densities. The Idaho Forestsnail, Allogona ptygophora, was also abundant in low elevation, floodplain habitats and often co-occurred with mountainsnails (Table 3). Most sites with the Rocky Mountainsnail were disturbed to some extent either by cattle or human recreational activities. Valley bottoms where these habitats are found are under intense pressure from development and other human uses, and most have been already modified.

The Subalpine Mountainsnail is thought to occupy streamside habitats rather than rocky slopes (Forsyth 1999, 2004 and references therein). We found the species along a small creek and seepage area amidst open and dry subalpine habitat.

It is possible that mountainsnails occupying rockslides and cottonwood floodplains represent different ecotypes or genetically unique populations. In particular, mountainsnails at some of the rocky slopes appeared to be isolated from other populations by vast stretches of unsuitable habitat and appeared superficially dissimilar in shell size and shape to snails other locations. Detailed study required to elucidate taxonomic relationships among mountainsnail populations is beyond the scope of this study but is needed to determine whether unique populations of conservation interest are present in British Columbia.

Coeur d'Alene Oregonian, Cryptomastix mullani (blue list; G4; S3S5) The Coeur d’Alene Oregonian is a medium to large snail (shell width up to 17 mm) with a reddish or yellowish brown shell. In adult snails, the apertural lip of the shell is thickened and strongly recurved, and there is a distinct white, peg-like protuberance or denticle in the aperture.

The species’ range extends from British Columbia south to Oregon and east to Montana (Forsyth 2004). In British Columbia, records exist from the Kootenay, Columbia, and Arrow Lake valleys in the southeast (Forsyth 1999). One subspecies, C. m. olneyae is known from British Columbia (Forsyth 2004), but other subspecies or even undescribed species may exist. Taxonomic relationships among the group have not been adequately studied, and the nominal species C. mullani may consist of a species complex (Forsyth 2004).

We found this species at only one of the 63 sites surveyed, near the BC-Idaho border south of Creston (Table 8, Fig. 3). This site represents a new locality record for the species and is the most southern record of the species in BC. Forsyth (1999) reported only one record for the species from the East Kootenay region, where most of our survey sites were located. The species may be more widespread in the West Kootenays, where most of the previous records are concentrated.

Banded Tigersnail, Anguispira kochi (blue-list; G5, S3) The Banded Tigersnail is a large snail (shell width up to 27 mm) with a brown shell containing a light, dark-bordered spiral band just above the periphery. This species has a wide range in western and central North America. In British Columbia, it is known only from the West Kootenay region, including Kootenay River, Kootenay Lake, and southern Columbia River valleys (Forsyth 2004).

We found this species at five of 63 sites surveyed (Table 9). Two locations were in the Kootenay Lake area and remaining three were to the east, near Yahk in the south and just west of Cranbrook in the north (Fig. 3). These records extend the known distribution

of the species in British Columbia up to about 60 km eastward of the Kootenay Lake. We did not locate the species at any of the sites surveyed east of Cranbrook.

Pale Jumping-slug, Hemphillia camelus (blue list; G3G4; S3) The Pale Jumping-slug is a large, pale brown or grey slug, up to about 55 mm in length when extended in movement. As in other jumping-slugs (genus Hemphillia), the visceral pouch is raised into a distinct hump and the internal shell plate is exposed through a slit in the mantle. The Pale Jumping-slug is one of three species of jumping-slugs (genus Hemphillia) from British Columbia, and the only species known from the mainland. It is widespread in southeastern British Columbia and also occurs in Alberta, northeastern Washington, Idaho, and northwestern Montana (Forsyth 2004).

We found the species at six sites, spread widely across the study area (Table 10; Fig 5). All but one site was in coniferous forest. The slugs were in moist microhabitats, under or within decayed logs in old-growth and second-growth stands. It has been reported from similar habitats in the past (Forsyth 2004).

Magnum Mantleslug, Magnipelta mycophaga (blue-list; G3, S2S3) The Magnum Mantleslug is a large slug, about 65 mm in extended length, with a very large mantle that covers most of the dorsal surface. When provoked, the slug spreads the mantle in a wing-like fashion (Forsyth 2004). The colour of the mantle and dorsum is light tan with black spots or mottling.

This species occurs in northeast Washington, Idaho panhandle, western Montana, and southeastern British Columbia (Forsyth 2004). In British Columbia, it is known from only a few records (R. Forsyth, pers. comm.). We found it at one site, near Mt. Fernie, which represents a new record and easternmost location for the species in the province (Fig. 5). The slug was in a subalpine area, in a very moist microsite along a seepage and small creek. The site supported dense shrubs and herbaceous vegetation. Similarly, in Montana and Idaho, the species is often found in association with water. Its habitat is described as moist, cool, coniferous sites, such as are found in moist valleys, ravines, and talus slopes (Montana Government, undated). The species occurs most often in relatively undisturbed forest with an intact duff layer rather than in logged over or otherwise disturbed areas (Montana Government, undated).

Pygmy Slug, Kootenaia burkei (G2) The Pygmy Slug was described only recently from specimens from northern Idaho and represents a new genus, Kootenaia (Leonard et al. 2003a). Since then, the species has also been reported from western Montana (Hendricks et al. 2007). It is a very small slug (length of adults 9 – 14 mm when extended in movement). The colour is pale grey or tan with blue flecking (Leonard et al. 2003). There are series of dark stripes on the tail, centered on pronounced, parallel grooves.

We found the Pygmy Slug at two localities in the West Kootenay region, representing first records of the species in Canada and extending its known distribution northwards (Table 12, Fig. 5). The two sites were about 100 km apart, east and west of Creston in the ICH biogeoclimatic zone. The habitat consisted of moist, mixed-wood riparian forest (Table 12). In Idaho and Montana, the species is also reported from similar habitats (Leonard et al. 2003a, Hendricks et al. 2007). Leonard et al. (2003a) noted that the

species is often found adjacent to water bodies, suggesting a requirement for high soil moisture and moderate ambient temperatures. In Montana, Hendricks et al. (2007) found groups of up to four individuals under downed wood and bark, among leaf litter, and within moss mats. At one of the sites (#49 in Table 12), we found concentrations of slugs within wet cottonwood leaves and decaying wood on the forest floor. At the other site (#45), we only found one small juvenile despite intensive searching.

The Pygmy Slug is of particular conservation interest because it appears to have a very limited and patchy global distribution. It is rated as critically imperiled (G2) both globally and nationally (N2) in the United States (NatureServe 2007). Additional surveys are needed to delineate its distribution in BC and to assess its status. The surveys should focus on moist forests in the ICH zone in the West Kootenays.

6.0 RECOMMENDATIONS We recommend continuation of gastropod surveys in the Kootenay Region to improve understanding of the distribution and status of species at risk. The region supports diverse and unique gastropod faunas, reflecting the diversity of habitats and complex terrain that contributes to geographic isolation of populations. In addition, the region abuts similar habitats in northern Washington, Idaho and Montana, where many gastropod species not yet recorded in BC occur. It is likely that additional species new to BC, such as Pygmy slug found in 2007, will be discovered.

Specific recommendations for 2008 are as follows: 1. Conduct surveys in the summer and fall with emphasis on filling data gaps on the distribution and habitat use of species at risk. Focal species should include the Subalpine Mountainsnail, Rocky Mountainsnail, Coeur d'Alene Oregonian, Magnum Mantleslug, and Pygmy Slug. 2. Increase survey coverage in areas close to the US border and in habitats that are likely to harbour species of conservation interest not yet documented from BC. Such species present in northern Idaho or northwestern Montana include the Marbled Jumping-slug (Hemphillia danielsi), Sheathed Slug (Zacoleus idahoensis), Papillose Taildropper (Prophysaon dubium), and Blue-grey Taildropper (P. coeruleum – interior population). 3. Increase survey coverage of the subalpine zone, including meadows and talus slopes that may support unique species or populations of gastropods.
