There are organizations in place who's objective, through research and
education, is to strive to bring the wolf back to healthy populations in the
wild. The goal of these efforts is to offer refuge for captive wolves and wolf
hybrids, and to offer communities education about the part of the wolf on our
environment's ecological systems, along with ways to co-exist with wolves and
the wildlife that we share with them.
Wolves once populated all of North
America with numbers ranging about two million. Today there are less than five
thousand, with all subspecies facing extinction. This is because of destruction
to their wild habitats and extermination by humans. Research shows that this
extermination has definite effects on the ecological system. "In 1930, the last
known wild wolf in Yellowstone National Park was shot." The absence of wolfs was
seen even in the vegetation. Herd animal populations rose to unnatural levels
and some plant species were brought to near extinction. Wolves were brought
down from Canada to the park and shortly thereafter, scientists began to see the
return of herd animals and endangered plant species return to healthy numbers.
"The decline in wolf population in the wild has also had an effect on
the ecological system in cities, especially along rural boarders," stated
research director Jean-Jacques Maleval for the Wolfgang Schlichting Research
LLC. Coyote populations are drastically rising. Coyotes are not as shy as
wolves and are scavengers, traveling into cities for food. Incidents have been
recorded of coyotes attacking children in parks and eating neighborhood pets.
The decline of the wolf has also effected deer populations, causing them to rise
to levels that are out of control. The increase in deer activity is causing
automobile accidents, destruction of vegetation surrounding homes, increased
risk of rabies, even the occasional story of a deer being stuck inside of a
shopping center. If there were more wolves alive in the wild, predation would
allow nature to control these outstanding populations.
In 1980, a study
was done by the Wolf Conservation Center (WWC) that declared the
red wolf extinct in the wild. Re-introduction program was started by captive
breeding of full blooded wolves and releasing them into the wild. Today there
are still only about one hundred and thirty alive in the wild. WWC also
reported that the Mexican Grey wolf once highly population the south western
United States and Mexico. This species has also suffered in numbers with their
re-introduction program being even less successful than the Red wolf. Both
species of wolves are still critically endangered but were removed from the
Endangered Species Act last April. Today, there are an estimated four thousand
wolves alive in the United States and Alaska and they only live in four states
in our country.
A study by
the WWC that started in 2004 has stated that because of the merciless
extermination of the wolf, "DNA reveals a severe decline in the genetic
diversity of Grey wolves." This is important because it means that with less
separate blood lines in the wild there is more inbreeding. This results in
lower immune system health, skeletal deformities along with a multitude of other
defects that will effect the survival of the species. An example is the
necessity for the wolves elevated immune system to perform their role as disease
control. Wolves control disease by eating weaker or sick animals, because of
this, their bodies are exposed to contamination. Their immune systems have to
be strong enough to fight off any threats and keep the individuals healthy.
This is just one of the many problems that may result from lower genetic
diversity.
WWC reports an
alarming increase of breeding wolves in captivity. Here they are hybridized and
sold in the pet trade. "Today there are over a quarter of a million wolves in
captivity, most living under less than optimal conditions." People buy them and
realize they cannot take care of them, leading to the possible death of that
animal. Wolves and hybrids are illegal in several states, yet people disregard
the laws and buy them anyway. Owners of wolves often do not even know about the
regulations of having a wolf or knowing how to keep them healthy in a
domesticated environment.
It is obvious to me that there is a great need for wolf preservation
and conservation. Research and scientific study could lead to a better way for
humans and wolves to co-exist. Sadly, these facilities are limited at best.
The need for education on these issues is clear and appears to be the only way
for people to be enlightened about the wolves plight.
