Overview: This
subspecies of the canada goose seems to be recovering from historically
low numbers. Although most nesting sights for this goose are found
on the Aleutian Islands of Alaska, Washington State contains critical habitat
for migratory feeding. In particular, the coastal portion of the
Klamath ecoregion is one very important stop on this species migratory
return from wintering in California back to the Aleutians. This species
was listed as Endangered in 1967 within the U.S. Department of Interior's
list of native endangered species. In 1991 it was down listed by
the U.S. Fish and Wildlife Service (USFWS) from endangered to its current
status of threatened. The initial cause for decline of this species
occurred due to introduction of the arctic fox (Alopex lagopus)
into nesting habitat. In the 1950’s the USFWS began efforts in lowering
fox populations and since these efforts, aleutian canada goose populations
have been steadily increasing. Recently, due to the success of these
recovery efforts, this species is being considered to be delisted from
the Endangered Species List. According to the USFWS, in the mid 70s
the population of this species was down to 800. Today it is estimated that
the population consists of around 20,000 geese. For more information

The
Alaska Division of the USFWS also has a fact sheet on this species which
can be downloaded at http://www.r7.fws.gov/es/te.html.
Distribution: Although
there currently is no population map for this species, its populations
within Washington are seasonally found in the Klamath ecoregion of Washington.
This area provides a great feeding stop for these geese as they return
from California to the Aleutian Islands for nesting season.
