Currently, there are more than 1,000 grizzly bears in the Yellowstone Ecosystem that occupy over 19,000 square miles. But such was not the case in the mid 1970s.

During that time, the grizzly bears' future was at stake. U. S. Fish and Wildlife Service biologist Chris Servheen affirmed that there were as few as 32 adult females in Yellowstone in 1981. They were concerned whether or not the bear population would be able to survive in the coming times.

For past 33 years, Servheen has been working with state and federal efforts for the recovery of grizzly bears. A lot of studies were done and now, abundance of data is available about the Yellowstone Grizzly.

With the conservation efforts, things have improved. Servheen said the bears have now shifted from recovery to coexistence status. "One of the big challenges with grizzly bears is of-coarse their omnivorous behavior and the fact they'll eat just about anything which continues to put them into conflict", affirmed Lauri Hanauska-Brown.

Hanauska-Brown stated that they are trying to have bears in those places, which are biologically and socially acceptable. Now, experts are raising awareness among people and educating them about bears. It is important to keep them in biologically more suitable areas.

It is said the federal government is going to start a road that could lead to setting the animals in North Cascades National Park. If it happens then it would be the first reintroduction of the grizzly bears.

Though bears are enjoying a recovery in the Yellowstone Ecosystem, there are places where things have not improved. In most of the United States, the grizzly bears are largely extinct. A number of factors are responsible for the same, including hunting, decades of shoot-on-sight treatment, reducing habitat and very low reproduction.
