Endangered Species Conservation Endangered Species Act of 1973 O Requires the Secretary of the Interior (through the U.S. Fish and Wildlife Service or the National Marine Fisheries Service) to identify and publish lists of species that are endangered or threatened O The lists include both U.S. and foreign species, and include animals, plants and invertebrates. O Decision whether to list must be based solely on the biological evidence O Anybody that can provide adequate evidence can make a proposal for listing. O Recognizes that species have aesthetic, ecological, educational, historical, recreational and scientific value to the nation and its people. O The Supreme Court has interpreted the ESA to mean that the value of species cannot be calculated, and that listed species should be protected whatever the cost Definitions •An endangered species means any species which is in danger of extinction throughout all or a significant portion of its range – other than a species of the Class Insecta determined by the Secretary to constitute a pest whose protection under the provisions of this chapter would present an overwhelming and overriding risk to man. •A threatened species is one that may soon become endangered if its situation is not improved. •A candidate species is one that is being considered for listing as an endangered or a threatened species, but is not yet the subject of a proposed rule. This designation does not confer any protection on the candidate species Steps involved in listing a species Endangered species O Cannot be "taken ". O "Take" means harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in such conduct. O Such activities directed against animals are illegal even on private land (not true for plants!) O A recovery plan must be developed and the recovery of the species must be monitored. O The species or its products cannot be exported or imported. Species, Subspecies, and Evolutionarily Significant Units • The original ESA applied only to named species and subspecies. • Some species exist as multiple reproductively isolated population segments, that might represent enough evolutionarily significant genetic diversity to make all of the segments worth preserving. • Anadromous fish populations (e.g. salmon) associated with specific rivers represent some of the main examples of such subdivided species. • In 1978 the ESA was amended to allow listing of "distinct population segments" of vertebrates. – populations that are reproductively isolated from other populations of the same species and might provide the genetic raw material for future evolutionary changes • 26 populations of West Coast salmon and steelhead were listed as endangered or threatened. http://www.ocregister.com/news/fish-193070-creek-steelhead.html Species given protection (Endangered + Threatened) Admin.

Applications for exemption from the ESA • Tellico Dam in Tennessee (Snail Darter fish) - exemption refused; later approved by Congress and President Carter. 1979. • Grayrocks Dam, WY (whooping crane) granted in 1979. • Bureau of Land Management for timber harvesting in Pacific Northwest (Northern Spotted Owl) : Led to a compromise: the Forest Ecosystem Management Assessment Team (FEMAT) 1993 Penguins: 17 species, feed mostly on krill Center for Biological Diversity sued to get protection for 11 species threatened by loss of sea ice. USFWS listed seven species: •African penguin •Yellow-eyed penguin •White-flippered penguin •Fiordland crested penguin •Humboldt penguin •Erect-crested penguin •Some populations of southern rockhopper penguin USFWS declined to review Emperor Penguin (star of “March of the Penguins”), despite 50% decline in population Island fox subspecies <100 Was 15 – now 38 Was 14 – now 54 Total in 1994: 6,000 Total in 2001: <1,660. San Miguel Island Fox: Historic: 450 1999: 15 (14 in captivity) • All four subspecies of Island Fox are threatened by introduced diseases, such as canine distemper, habitat alteration related to the introduction of pigs, goats, deer, cattle, sheep, and elk, and predation by golden eagles • 4-17-03: The Center for Biological Diversity sued the U.S. Fish and Wildlife Service for refusing to list the island foxes as endangered species. • 3-4-04: Channel Island Fox listed as Endangered Endangered Species at Upper Newport Bay 3 Clapper Rail Rallus longirostris Light-footed clapper rail Rallus longirostris levipes FE, SE Least Tern Sterna antillarum California least tern Sterna antillarum browni FE, SE Black Skimmer Rynchops niger http://www.arkive.org/black-skimmer/rynchops-niger/video-08.html http://ibc.lynxeds.com/video/black-skimmer-rynchops-niger/several-birds-skimming-canal Savannah Sparrow Passerculus sandwichensis Belding’s savannah sparrow Passerculus sandwichensis beldingi SE Other Endangered Species of Southern California Santa Ana Sucker Tidewater Goby California gnatcatcher Riverside Fairy Shrimp California Gnatcatcher Polioptila californica Coastal California gnatcatcher Polioptila californica californica FT Santa Ana sucker (Catostomus santaanae), Tidewater Goby Scientific Name Eucyclogobius newberryi Vernal Pool Fairy Shrimp Branchinecta lindahli (Picture of a close relative) Red Abalone (Cabrillo Marine Aquarium) Abalone (8 species in E.

Sea otter decline in the Aleutian Islands Alaska Aleutian Islands Decline Continuing 2000-2003 Status of Sea Otter Stocks Reintroduced in 1969 and 1970: 2005: (In response to lawsuit from Center for Biological Diversity) Southwest stock listed as Threatened 2006: Center for Biological Diversity sued to compel the U.S. Fish and Wildlife Service to designate critical habitat Southeast stock is increasing! Ecosystem collapse in the Aleutian Islands (N. Pacific) 1977-2000 • Overfishing • Decline in Steller sea lions and harbor seals (usual food of Killer whales) • Increased predation on sea otters by killer whales. • Decline in Sea Otters • Population explosion (8x increase) of sea urchins (usual food of sea otters) • Depletion of kelp beds (food of sea urchins) • Depletion of king crabs, shrimp, smelt • Less food for seals and sea lions California Sea Otter •Thought to have numbered 20,000 before exploitation •Thought to be extinct until about 300 discovered in 1938 •Listed as Threatened since 1977 •Slowly recovering: 2007 count: 3,026 The California Endangered Species Act (1970) Reauthorized 1997 • California has the largest number of rare plant and animal species of any State in the nation • California was the first State to establish an Endangered Species Act • Parallels the main provisions of the Federal Endangered Species Act • Administered by the California Department of Fish and Game (DFG) • Limited to species or subspecies native to California • Consultation: State lead agencies are required to consult with DFG to ensure that any action it undertakes is not likely to jeopardize the continued existence of any endangered or threatened species or result in destruction or adverse modification of essential habitat • California law allows the designation of a species as Fully Protected, which is a greater level of protection than is afforded by the California Endangered Species Act. – Such a designation means the listed species cannot be killed, nor can its habitat be destroyed if this would ultimately lead to its death or destruction. – Fully Protected Species has been given to the Southern Sea Otter, California Condor, California Least Tern, Golden Eagle, Peregrine Falcon, Bighorn Sheep, Salt Marsh Harvest Mouse and many others.
