110 Success Stories for Endangered Species Day 2012

Alaska        


Aleutian Canada goose (Branta hutchinsii leucopareia)

Status: Delisted Critical habitat: none
Listed: 3/11/1967 Recovery plan: 9/30/1991
   

Range: AK(b), CA(s), OR(s), WA(m) ---

SUMMARY
In the 1960s the Aleutian Canada goose was feared extinct due to predation by non-native foxes introduced to its nesting island, and to a less degree, by excessive hunting and loss of winter and migration habitat. It was rediscovered in 1962. In 1967 it was listed as an endangered species and grew from ~790 birds in 1975 to ~60,000 in 2005. It was declared recovered and removed from the endangered list in 2001, seven years earlier than projected by its recovery plan.

American peregrine falcon (Falco peregrinus anatum)

Status: Delisted Critical habitat: 8/11/1977
Listed: 6/2/1970 Recovery plan: 6/30/1991
   

Range: AL(m), AK(b), AZ(b), AR(m), CA(b), CO(b), CT(b), DE(b), DC(m), GA(b), ID(b), IL(b), IN(b), IA(b), KS(m), KY(b), LA(m), ME(b), MD(b), MA(b), MI(b), MN(b), MS(m), MO(m), MT(b), NE(b), NV(b), NH(b), NY(b), NM(b), NJ(b), NC(b), ND(m), OH(b), OK(m), OR(b), PA(b), RI(b), SC(b), SD(b), TN(b), TX(b), UT(b), VT(b), VA(b), WA(b), WV(m), WI(b), WY(b) ---

SUMMARY
The use of DDT and other organochlorine pesticides thinned American peregrine falcon eggshells, causing reproductive failure and population declines. The banning of DDT, captive-breeding efforts and nest protections allowed falcons to increase from 324 breeding pairs in 1975 to 3,005 pairs as of 2006. The species was delisted in 1999.

Arctic peregrine falcon (Falco peregrinus tundrius)

Status: DelistedCritical habitat: none
Listed: 6/2/1970Recovery plan: 6/30/1991
   

Range: AL(m), AK(b), AZ(m), AR(m), CA(m), CO(m), CT(m), DE(m), DC(m), FL(m), GA(m), ID(m), IL(m), IN(m), IA(m), KS(m), KY(m), LA(m), ME(m), MD(m), MA(m), MI(m), MN(m), MS(m), MO(m), MT(m), NE(m), NV(m), NH(m), NY(m), NM(m), NJ(m), NC(m), ND(m), OH(m), OK(m), OR(m), PA(m), RI(m), SC(m), SD(m), TN(m), TX(m), UT(m), VT(m), VA(m), WA(m), WV(m), WI(m), WY(m) ---

SUMMARY
The Arctic peregrine falcon declined due to the egg shell-thinning effects of DDT and other organochlorine pesticides. Its listing as an endangered species in 1970 (along with other birds of prey) prompted the EPA to ban DDT in 1972. Counts of migratory Arctic falcons increased from 103 in 1976, to 1,017 in 2004. The species was downlisted to threatened in 1984 and delisted in 1991.

Blue whale (Balaenoptera musculus)

Status: EndangeredCritical habitat: none
Listed: 6/2/1970Recovery plan: 10/23/1998
   

Range: AK(s), CA(s), FL(o), HI(s), ME(o), MD(o), MA(o), NH(o), NY(o), NC(o), OR(m), RI(o), SC(o), WA(m) ---

SUMMARY
The blue whale population was reduced by as much as 99 percent due to whaling that occurred before the mid-1960s. The number of whales reported off the coast of California, the largest stock in U.S. waters, increased from 704 in 1980 to an estimated 2,497 in 2010.

Bowhead whale (Balaena mysticetus)

Status: EndangeredCritical habitat: none
Listed: 6/2/1970Recovery plan: none
   

Range: AK(s) ---

SUMMARY
Bowhead whales in the Western Arctic were severely depleted by commercial whaling which reached a peak between 1898-1919. Whaling was banned in 1946. They are currently threatened by increased oil and gas drilling and global warming. Approximately 3,000 bowheads remained when commercial whaling ceased. Following Endangered Species Act listing in 1970, the Western Arctic population increased from 5,189 in 1978 to 11,836 in 2004. The population is likely larger today.

Fin whale (Balaenoptera physalus)

Status: EndangeredCritical habitat: none
Listed: 6/2/1970Recovery plan: 7/30/2010
   

Range: AL(o), AK(s), CA(s), CT(s), DE(s), FL(s), GA(s), HI(s), LA(o), ME(s), MD(s), MA(s), MS(o), NH(s), NY(s), NJ(s), NC(s), OR(s), PA(s), RI(s), SC(s), TX(o), VA(s), WA(s) ---

SUMMARY
Fin whales were hunted in all the world's oceans for the first three-quarters of the 20th century, causing population decline. Ongoing threats include illegal and legal whaling, vessel collisions, fishing gear entanglement, reduced prey and noise. Total population size is unknown, but both the North Atlantic and North Pacific populations increased between 1995 and 2009.

Gray whale (Eastern North Pacific DPS) (Eschrichtius robustus pop. 3)

Status: DelistedCritical habitat: none
Listed: 6/2/1970Recovery plan: none
   

Range: AK(b), CA(b), OR(b), WA(b) ---

SUMMARY
Gray whales declined precipitously due to whaling, becoming extinct in the Atlantic, endangered in the Eastern North Pacific and extremely endangered in the Western North Pacific. They are threatened by oil and gas drilling and coastal development. In 1968, there were 13,426 Eastern North Pacific gray whales. The species was was listed as endangered in 1970 and removed from the list in 1994 when the population reached 20,103 whales. The 2009 population was estimated to be 21,911.

Humpback whale (Megaptera novaeangliae)

Status: EndangeredCritical habitat: none
Listed: 6/2/1970Recovery plan: 11/15/1991
   

Range: AL(o), AK(s), CA(s), CT(s), DE(s), FL(s), GA(s), HI(s), LA(o), ME(s), MD(s), MA(s), MS(o), NH(s), NY(s), NJ(s), NC(s), OR(s), RI(s), SC(s), TX(o), VA(s), WA(s) ---

SUMMARY
Humpback whale populations were greatly depleted by commercial whaling by the early 1900s. In 1966, the entire North Pacific humpback population was thought to number only around 1,200 animals. As of 2010, the total population of North Pacific humpback was estimated at 21,808.

Steller sea-lion (eastern DPS) (Eumetopias jubatus (eastern DPS))

Status: EndangeredCritical habitat: 8/27/1993
Listed: 4/5/1990Recovery plan: 2/29/2008
   

Range: AK, CA, OR, WA

SUMMARY
The Steller sea-lion (eastern DPS) declined due to exploitation, predator control and prey base declines. These threats substantially declined following its listing as an endangered species in 1990 and designation of critical habitat in 1993. Its population increased about 21,000 animals in 1989 to 63,488 in 2009. In 2012 it was proposed for delisting due to high total numbers, but California trends remain weak, and the southernmost portion of its range has not been reoccupied.

Steller sea-lion (western DPS) (Eumetopias jubatus (western DPS))

Status: EndangeredCritical habitat: 8/27/1993
Listed: 4/5/1990Recovery plan: 2/29/2008
   

Range: AK(b) ---

SUMMARY
The Steller sea lion is threatened by loss of its prey base to unsustainable commercial fisheries, predation, toxins and global climate change. It declined in every count from 1970-2000 but increased in 2002-2004 as fishing restrictions took effect. As of 2008 the Alaska population was estimated at 45,000, which is 15,000 more animals than at the time of listing in 1990.
