The Columbian white-tailed deer, an endangered species
that lives in the United States, has slowly been making a recovery since 1967
when it’s numbers were at 467. The
species joined the endangered species list in the first group of animals that
are protected under the Endangered Species Act.
It joined this group in 1967 along with the Bald Eagle and the
California condor. The Columbian
white-tailed deer live around the Columbia River area and have been making
great progress. As of 2015, there are
now nearly 1,000 deer in this area. The
recovery of this species has been so great that the U.S. Fish and Wildlife
Service proposed that the group of deer move from the endangered list to the
threatened list.
Biologists and government workers added the Columbian
white-tailed deer to the endangered species list because of the great reduction
of deer. This reduction was a result of
habitat loss and modification by human activities. Modification of the habitats by human
activities was led by issues such as farming, logging, and commercial/residential
development. Habitat loss was due to
natural causes such as floods that destroyed the deer habitats. Since the habitat loss was so rapid and
extreme, the deer population did not have a place to live and slowly started to
die off.
The most beneficial solution to save the species is
the creation of Columbian white-tailed deer refuges. The U.S. Fish and Wildlife Service relocates
deer into the refuges to prohibit them from having too much experience with the
outside environment. The agency has also
relocated elk, the animal that competes with the white-tailed deer for
food. Wildlife officials have even gone
to the extreme measures of killing off coyotes that prey on deer, specifically
to protect the deer. The workers at the
refuges put most of their time into rebuilding habitats and doing everything in
their power to remove the species from the Endangered Species list. Ferrier mentioned, “We do pasture work and
riparian plantings because they like both grass and woody species. We do that and invasive species control.” Another large solution to the problem has
been the completion of a new dike by the U.S. Army Corps of Engineers. This new dike drastically reduces the risk of
the Columbia River flooding the deer refuge.
The main possible side-effect of the return of the
deer population is the new competition.
The other species in the area have been used to living without the Columbian
white-tailed deer. If the species is
eventually released back into the wild, the competition for habitat and food
will be greater and more difficult than it was before.
