In light of its restricted range, and a current population size that is almost certainly less than the 5,000 to 10,000 breeding birds estimated in the early to mid-1990s, the ashy-storm petrel is listed as Endangered on the IUCN Red List (1) (2). Fortunately, despite the threats described, most of the breeding colonies are on islands either protected from development or subject to sensitive management (2) (3). Current conservation proposals include eradication of all introduced predators from nesting islands, an investigation of the impacts of light, chemical and plastics pollution, and continued monitoring of population trends (2). Presently, the ashy storm-petrel is designated by the California Department of Fish and Game as a Bird Species of Conservation Concern, but as of May 2008 it is also under review for protection under the Endangered Species Act (ESA) (6). If listed under the ESA, the ashy storm-petrel will benefit from the compulsory development of a recovery plan, protection and restoration of critical habitat, scientific research and public education (7) (8).
