Yellowstone National Park’s grizzly bears have potential to continue thriving in long term
A new study suggests that grizzly bears, which were facing risk owing to depletion in population, are now thriving in the Yellowstone National Park region. In fact, the Interagency Grizzly Bear Study Team has unveiled that the bears have potential to continue to thrive in the long term.
In the study, published in Molecular Ecology, the team has looked at 729 bears and came to a conclusion that the population of grizzly bears in the Greater Yellowstone Ecosystem has increased by four times since 1980s. The population has increased from 100 to 480.
Another thing noticed by the researchers is genetic diversity has been found to be stable. There is a need to consider genetic diversity aspect, said the researchers. It is because genetic diversity is important for survival of bears as well for adapting to environmental changes.
Study’s co-researcher Pauline Kamath, a geneticist, said that the results are encouraging and shows that the efforts to conserve the population are working in right direction. Grizzly bears live in a few places around the Northwest, but they have nothing to do with the bears in the Yellowstone.
The research has come at a time when the US Fish and Wildlife Service is thinking about a delisting rule for the threatened species. In 1975 under the Endangered Species Act, the bear was included as a threatened species.
