Abstract: This amendment to project 11100853, Pigeon Guillemot Restoration Research in Prince William Sound, Alaska, provides an opportunity to restore the population of Pigeon Guillemots (Cepphus columba) in Prince William Sound, Alaska, which has fallen by more than 90% at the Naked Island Group since 1989. A restoration plan for Pigeon Guillemots in PWS was prepared to address the species’ lack of population recovery following injury by the 1989 Exxon Valdez oil spill. Predation on nests and adults by mink is now the primary limiting factor for guillemot reproductive success and population recovery at the most important historical nesting site for guillemots in PWS (i.e., the Naked Island group). Mink on the Naked Island group are descended in part from fur farm stock and apparently arrived on the island group during the 1980s. Control of predatory mink at these islands was selected as the preferred restoration alternative because it is feasible and most likely to result in the recovery of guillemots in PWS. Other alternatives are either currently unavailable or unlikely to be effective. A control effort is likely to be successful but if it is not then the agencies would discuss alternatives, one of which would be to amend the EA and remove the remaining mink from the islands. Potential negative effects of the preferred alternative are either negligible or largely avoidable. The Naked Island group guillemot population would likely increase five-fold within the first 10 years following mink control, and the Sound-wide population of guillemots would likely increase within 15 years of mink control at the Naked Island group, once the Naked Island group had become a source population for other parts of PWS.

Phase I: Completion of the NEPA process for the proposed action. (Completed) Phase II: Control of predatory mink on the Naked Island Group, PWS Alaska
