The return of wolves to Yellowstone National Park is having an interesting — though not surprising — effect on the larger ecosystem, affecting everything from grizzly bears to elk to berry bushes, according to new research from Oregon State University and Washington State University. The new research has found that grizzlies are benefiting greatly from
Fifteen years after wolves were returned to Yellowstone National Park the health of the overall ecosystem is overwhelming and obvious. This is the observation made by scientists in a new report published in the journal Biological Conservation. For the first time in 70 years, the young aspen and willow trees are not being eaten before
Of course, we here at the Sierra Club love animals. To help share that love, we put together this amazing slideshow of endangered animals in photos by Joel Sartore. Some are cuddly-looking, some, even I admit, are slimy — all deserve protection.
The affects that climate change will have on the Greater Yellowstone Ecosystem is the focus of a recent study which looked specifically on how the cycle of fire and regrowth will change as temperatures continue to rise over the rest of the 21st century.
“The loss of apex consumers is arguably humankind’s most pervasive influence on the natural world,” argue the authors of a new report published in the journal Science, which looked at the decline of large predators and other ‘apex consumers’ at the top of the food chain.
Following up on the story I wrote last week on North America’s endangered bison, here’s a full repost of an email I just received from the Defenders of Wildlife. All they wanted was some food. Now some of the last true, wild bison in America face slaughter simply for leaving Yellowstone National Park. These majestic
For the first time since the 1800s, a small group of wild bison was herded Wednesday through fresh-fallen snow to reach their historical grazing grounds north of Yellowstone National Park. As pronghorn antelope and mule deer scattered to avoid the procession, park employees and state livestock agents on horseback pushed the 25 bison about 10
Despite the news yesterday that the wolf population in Yellowstone has decreased 27%, the Bush administration said today that they will remove the gray wolf from the endangered species list in the Midwest and in the area surrounding Yellowstone National Park. [social_buttons] The Bush administration has tried to remove the wolves’ federal protections twice before,
After completing its annual wolf population estimate, Yellowstone National Park has announced that the number of wolves inside the park has declined by 27% since the end of 2007. 124 wolves are now thought to reside in the park, down from 171. Is this a normal fluctuation?
A federal judge has banned snowmobiles from Yellowstone National Park. He said that a plan approved by the Bush Administration to allow 500 snowmobiles to travel daily through Yellowstone and Grand Teton National Parks in the winter months would cause damaging noise pollution, air pollution, and would also stress wildlife.
A new study in the journal BMC Ecology indicates that coastal wolves in British Columbia switch to eating salmon in the fall as a primary food source, rather than deer. Scientists arrived at this conclusion after analyzing wolf poop they collected over a four year span. Among the thousands of stools that were collected by
