California brown pelican is
removed from state Endangered Species List in a vote by Fish and
Game Commission in February 2009.
The California brown pelican which breeds in the Gulf of
California, Baja California and north to the Channel Islands off
shore of Southern California. It is the Pelecanus occidentalis
californicus, a subspecies of the brown pelican. Brown pelicans
are still protected under the federal Endangered Species Act,
while the U.S. Fish and Wildlife Service (USFWS) reviews their
status nationwide. Meanwhile... read on...
The California Fish and
Game Commission voted unanimously to remove the California brown
pelican from the state endangered species list for the first
time ever that a delisting has occurred. The commission
president said that the California Endangered Species Act is
both loved and hated as we humans struggle to create balance
with the impacts of endangered status and native speciess’ needs.
The California brown pelican is the first species to fully
recover in the close to 40 year history of the organization. It
is still illegal to kill or harm a brown pelican in California,
but the brown pelican was removed or de-listed due to
recommendations that examined an increased breeding
population on West Anacapa Island in the Channel Islands,
expansion of breeding pairs on Santa Barbara Island, increased
productivity and fledgling numbers, and the fact that nesting
sites are under generally-protective National Park Service (NPS)
ownership or management. In spite of known threats, the breeding
population of brown pelicans in California has increased
substantially in recent years.
Fully Protected Species under the Fish and Game Code, the
California brown pelican will still hold protected status,
though not endangered species status. Researchers in the Channel
Islands and Mexico where the brown pelicans nest contributed
field work demonstrating the unique roost site needs of brown
pelicans during the breeding and non-breeding seasons. National
Park Services employees assisted in monitoring and enforcement
efforts and wildlife rescue and rehabilitation groups have
helped recover brown pelicans, too.
Following reproductive failure, severe population decline and
colony losses from the 1940s to 1970s, the California brown
pelican was federally listed as endangered by the USFWS in 1970
and state-listed as endangered by the California Fish and Game
Commission in 1971.
The decline of the California brown pelican and other species
due to the effects of the persistent pesticide DDT was one of
the major events that helped to develop public concern for the
environment and related laws in California in the late 1960s and
early 1970s.
Contamination by the pesticide DDT resulted in thin eggshells
that broke under the pressure of incubating adult pelicans. The
pesticide was determined to be the primary cause of reproductive
failures and population declines in Southern California and
coastal Baja California, and was banned in the U.S. in 1972.
Human disturbance of breeding colonies and roosts also
contributed to population declines and poor reproduction. Oil
spills and entanglement in fishing tackle are other known
threats to pelicans.
Recovery efforts in the last three decades have resulted in the
seabird again becoming a common resident of the west coast of
the U.S., after being reduced to small numbers from the 1960s to
1980s. There are now an estimated 8,500 breeding pairs in the
Channel Islands, the only area in California where brown
pelicans nest.
While the California brown pelican will no longer be considered
endangered under the state endangered species act, they – like
any other wild animal – still must not be harassed or injured by
anyone. Seabirds and shorebirds are often seen resting on
beaches, islands, estuaries and jetties after spending hours
searching for prey to sustain themselves. People who enjoy using
those areas should keep children and dogs away from the birds to
ensure they are not disturbed during these critical resting
periods. |
