Blue-grey Taildropper (Prophysaon coeruleum) is endemic to western North America. Adults are small, slender slugs that grow up to 45 mm in length. The slug?s most obvious distinguishing feature is the overall solid and often brilliant-bluish body colouration.
Blue-grey Taildropper is assessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as Endangered. The species is listed in Canada on Schedule 1 of the Species at Risk Act (SARA) as Endangered due to the species? very small extent of occurrence (~ 150 km2) and area of occupancy (< 5 km2), and a continuing decline is projected in quality of habitat. Blue-grey Taildropper is only known from 11 locations within the Victoria area on southern Vancouver Island. In British Columbia (B.C.), Blue-grey Taildropper is ranked S1 (critically imperiled) by the Conservation Data Centre and is on the provincial Red list. The B.C. Conservation Framework ranks Blue-grey Taildropper as a priority 1 under goal 3 (maintain the diversity of native species and ecosystems). Recovery is considered biologically and technically feasible.
The population and distribution goal is to ensure the persistence of all1 known (and newly recorded) locations of Blue-grey Taildropper throughout the species? range in B.C.
The recovery objectives are:
1. to secure protection2 for the known locations (and new locations) and habitats of Blue-grey Taildropper.
2. to assess and mitigate the extent of the current threats (IUCN-CMP Threat3 1, 4, 5, 6, 7, 8, 9) at all locations in B.C.
3. to address knowledge gaps (e.g., habitat requirements, range extent within Vancouver Island, and potential range extent in the Kootenay region) for Blue-grey Taildropper.
The recovery of Blue-grey Taildropper in B.C. is considered technically and biologically feasible based on the criteria outlined by the Government of Canada (2009)
