As Yellowstone grizzly population rises, so does death toll

More grizzlies got into trouble in the Yellowstone area this year, but that is sort of a good thing . . .

The number of grizzly bear deaths or removals in the Yellowstone region climbed to an all-time high in 2015, but biologists say they’re not worried about the animal’s long-term survival in the area.

The known or suspected deaths of 55 bears shouldn’t interfere with plans to remove the region’s grizzlies from protection under the Endangered Species Act, Frank van Manen, leader of the Interagency Grizzly Bear Study Team, said Wednesday.

“This year should be considered within the context of what we’ve seen in terms of the long-term trend,” van Manen said.

More grizzly bear monitoring action as the feds move towards removing the animal from the endangered species list in some areas . . .

Twenty-four grizzly bears have been captured so far this year in and around Yellowstone National Park as wildlife managers start another season of research toward a potential lifting of federal protections.

The Interagency Grizzly Bear Study Team captured the grizzlies in Yellowstone and Grand Teton national parks and outside the parks in Montana and Wyoming.

Teams are now starting to trap grizzlies in eastern Idaho to attach radio or GPS collars.

Is a gunshot like a dinner bell for bears?

A group of researchers is performing a very interesting study on how bears and hunters interact . . .

From almost four miles away, the grizzly bear appeared to have picked up the elk carcass’ stench.

Researchers were able to revisit the grizzly’s trek as it walked along the edge of a lake, eventually swimming across the end of the water to reach the carcass, because the bear was wearing a GPS collar. The same location information showed the bear visiting and moving away from the carcass several times in following days.

A current grizzly bear diet study is an important factor in determine whether to continue federal protections . . .

Researchers say a study on Yellowstone ecosystem grizzly bear diets should be completed this October.

The study will help determine whether managers will recommend ending federal protections for the species.

Interagency committee wants full picture of grizzly bear diet before delisting

The Interagency Grizzly Bear Committee plans a close look at the grizzly bear’s overall diet . . .

To ensure they’ve got the best look at how well grizzly bears can endure in the Greater Yellowstone Ecosystem, researchers want a full picture of the predators’ diet before another attempt to remove them from endangered species protection.

The Interagency Grizzly Bear Committee hopes to convince the 9th U.S. Circuit Court of Appeals it was justified in delisting the big bears from the federal Endangered Species Act…

Grizzly bear deaths spike in Yellowstone region this summer

It could just be statistical anomaly, but there have been 16 grizzly bear deaths in the Yellowstone region this summer. Most are natural losses, but they are much higher than normal . . .

Bear biologists are refraining from assigning a single reason for a two-fold increase in the rate of natural grizzly bear deaths in the Yellowstone National Park region.

Ten of the 16 grizzlies that have met their ends this summer have died of natural causes, according to data from the Interagency Grizzly Bear Study Team.

Historically, humans are to blame for more than 75 percent of the bear deaths in the first half of the summer. While the rate is just 37 percent this year, it is derived from a small sample size, and biologists aren’t jumping to any conclusions.
