Action timeline

May 1, 2001 – The Center filed a citizen petition with the National Marine Fisheries Service to have Puget Sound’s orcas listed as endangered under the Endangered Species Act.

July 1, 2002 – The Fisheries Service announced that Puget Sound’s killer whales were “not significant” enough to warrant protection under the Endangered Species Act. The Center responded by partnering with nearly a dozen other conservation groups to file a lawsuit against the agency for its failure to protect the whales.

2003 – The courts found the Fisheries Service’s 2002 announcement to be unlawful, thereby forcing the agency to reverse its decision and take steps toward species protection.

November 29, 2006 – A total of 2,500 square miles of Puget Sound, Haro Strait, and Juan de Fuca Strait was designated as critical habitat for the Puget Sound killer whale.
