Action timeline

December 5, 2000 – The Center, the Sierra Nevada Forest Protection Campaign, and 16 other environmental groups petitioned the U.S. Fish and Wildlife Service to list the fisher as endangered under the federal Endangered Species Act in its West Coast range.

April 2003 – A federal judge sided with the Center and allies in a suit filed to force the Service to process a listing petition for the fisher submitted by the Center, the Sierra Nevada Forest Protection Campaign, and 16 other environmental groups. The judge ordered that an initial decision on the status of the fisher be made within 90 days.

June 2003 – The Service issued an initial positive decision that the Pacific fisher in the forests of California, Oregon, and Washington qualifies as an endangered species.

April 8, 2004 – The Service published a proposed rule that found that Endangered Species Act listing was “warranted but precluded” for the Pacific fisher and made the fisher a candidate species, giving it no protection.

February 28, 2007 – The Center and other conservation groups intervened in a timber-industry lawsuit that sought to remove the fisher from the list of candidate species. The lawsuit was brought about on the claim that the Pacific fisher is a “distinct population segment” of a subspecies and therefore should not be considered for protection.

January 2008 – The Center petitioned to list the Pacific fisher as threatened or endangered under the California Endangered Species Act.
