... As in previous Living Landscapes reports on the terrestrial snails and slugs (Forsyth 1999(Forsyth , 2005, this report gathers together information on a single region of British Columbia. The geographic area covered by this report is very large (about 265,000 km 2 ), stretching from B.C.'s northern boundary with the Yukon and Northwest Territories (60°N) south to the Rocky Mountains where it abuts the Fraser River drainage. ...
... (Figure 8); and outside the region from Lac la Hache, 820 m a.s.l. (Forsyth 2005). At both localities snails were found under dead wood or sticks. ...
... The Kiskatinaw site has young cottonwoods, while the Lac la Hache site was relatively dry, open Douglas-fir forest. See Forsyth (Forsyth 2004(Forsyth , 2005 for descriptions of this species. In the Peace River -northern Rockies region this species was found in forests and open subalpine habitats at elevations between 434-1265 m. ...

Less than 5% of the original tall grass prairie in North America remains. A portion of this remnant, composed of wetland, grassland and forest, is protected by the Nature Conservancy of Canada (NCC) in southern Manitoba. This heterogeneous ecosystem has rich biodiversity; however, gastropods have not been surveyed in Canada’s tall grass prairie. We studied gastropods in Prairie, Wet Meadow, Forest, and Wet Forest habitats of the Manitoba Tall Grass Prairie Preserve that vary with respect to land management practices (prescribed burning, grazing by cattle). Gastropod community composition was unique in the Prairie where mounds of grass litter form permanently moist cavities harbouring aquatic species, while dry-habitat species colonized the upper parts of these mounds. Gastropod communities in Prairie habitats were negatively affected by grazing and burning that occurred in the five years prior to our survey. Unburned Forest patches included both forest gastropod species and edge effect influenced open-habitat species and harboured the most diverse gastropod communities. These unburned Forest patches potentially provide a species pool for post-burn prairie recolonization. The gastropod community of Wet Meadows was not affected by grazing and was composed mainly of aquatic species. In this gastropod survey five species were recorded from Manitoba for the first time. The rare Blade Vertigo (Vertigo milium) is also reported.

Vertigo cristata, previously unreported from the U. S. A., was located at 84 sites in northern Minnesota, northern and southwestern Wisconsin, the Upper Peninsula of Michigan, and also in Ontario on Manitoulin Island and the northern tip of the Bruce Peninsula. It was found in nine habitats (carbonate cliffs, lakeshore carbonate ledges, igneous cliffs, sandstone cliffs, rocky woodlands, igneous lakeshore outcrops, swamp forests, tamarack wetlands, and white cedar wetlands) and was essentially confined to areas north of 45°N. It was most frequently encountered on igneous rock outcrops, where it was observed in over 67% of surveyed sites. V. cristata individuals were easily separated from V. gottldi (A. Binney, 1843), with which it has often been lumped as a subspecies, as well as from other central U. S. Vertigo taxa, including V. modesta modesta, V. paradoxa, and V. meramecεnsis.

The land snail Vertigo nylanderi, previously reported from only six modern global sites, was located at 22 stations in north-central Minnesota, northern Michigan, and eastern Wisconsin. Its populations are limited to nutrient-rich, forested wetlands (typically dominated by Tamarack or Black Ash) that are underlain by calcareous substrates. Most sites are within 40 km of the Lake Michigan and Lake Huron shorelines. This species was found to be morphologically distinct from other conchologically similar taxa such as V. arthuri (von Martens, 1884), V. hubrichti (Pilsbry, 1934), and V. paradoxa Sterki, 1900. Although 54 other terrestrial gastropod taxa have been observed to coexist with V. nylanderi, only 12 of these occur in at least 50% of sites. The cool, wet, calcareous habitats that support V. nylanderi appear to be similar to late Pleistocene environments, and it is possible that this species represents a relict from that period.
