The Yellowstone grizzly bear was removed from the Endangered Species List in 2007. Their population continues to grow, increasing by 4 to 7 percent a year. Their range is still expanding both north and south of Yellowstone National Park.
But conflicts remain. In 2008, grizzly deaths in the Yellowstone ecosystem were reported to be high. Seventy-nine bears were killed. Another year of such high mortality could trigger a review of the grizzly’s listing status.
Two of the grizzly’s key food sources, cutthroat trout and white bark pine seeds, are increasingly uncertain. Trout runs have been eliminated on many streams, and white bark pine trees are suffering from blister rust and beetle damage across much of their range. But this year, the remaining trees are producing a strong seed crop and the bears are harvesting good calories from seeds and moths in preparation for winter.
The agencies and concerned conservation groups are monitoring the bears closely. For more information, please click on the links below:

re: grizzly deaths in 2008 – who/how/why were the bears killed? Euthanized by park service, killed by hunters, or…?
Your article is contradictory. You state that the population continues to grow while also stating the bear deaths are increasing. So why is this a problem? I think the key statement is that the population is growing. Sounds like an ongoing success.
It is not conceivable that grizzly bears can survive human development and exploitation of the Rocky Mountains. Is it conceivable that human development and exploitation of the earth will be sustainable after other natural species have been extinguished?
