This multispecies management plan has been developed to guide the management of Magnum Mantleslug (Magnipelta mycophaga), Pygmy Slug (Kootenaia burkei), and Sheathed Slug (Zacoleus idahoensis), the entire Canadian distributions of which are restricted to southeastern British Columbia. Pygmy Slug and Sheathed Slug are found mainly in the West Kootenay region, and Magnum Mantleslug ranges farther to the east, west, and north of the Kootenay area of the province. Magnum Mantleslug, Pygmy Slug, and Sheathed Slug are treated together in this management plan because they occur in the similar forest habitats of southeastern British Columbia and because similar management measures apply.
Each of the three species has been designated as of Special Concern by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). Magnum Mantleslug is on Schedule 1 of the Species at Risk Act (SARA) and Pygmy Slug and Sheathed Slug are not yet listed under this Act. In British Columbia, Magnum Mantleslug is ranked S2S3 (imperiled/vulnerable), Pygmy Slug is ranked S3 (vulnerable) and Sheathed Slug S3 by the B.C. Conservation Data Centre. The B.C. Conservation Framework ranks Magnum Mantleslug, Pygmy Slug and Sheathed Slug all as a priority #2 under goal 3 (maintain the diversity of native species and ecosystems).
