| Whitebark pine (Pinus albicaulis) is an Idaho Bureau of Land Management (BLM) Special Status Species and a Federal Candidate species under the Endangered Species Act. The US Fish and Wildlife Service issued their twelve (12) month finding on a petition to list whitebark pine as a threatened or endangered species on July 19, 2011 in Federal Register Volume 76, Number 138. The finding was that of “warranted but precluded” with a Listing Priority Number (LPN) of 2. Whitebark is long-lived, five needle pine of high elevations. On BLM administered lands in Idaho it occurs near US Forest Service lands and as isolated populations on mountain islands. It is a keystone species, important to numerous species of wildlife. Major threats to the persistence of whitebark pine are an exotic fungus, white pine blister rust (Croartium ribicola), mountain pine beetle (Dendroctonous ponderosae) infestations, succession, fire and fire suppression, and climate change.
