A University of Wyoming study shows that elk don’t respond frequently enough to threats from wolves to impact body fat and pregnancy rates. Wolves’ effects on elk populations is limited to direct predation, not harassment or stress that leads to lower pregnancy rates or poor body composition, according to the study.
Federal wildlife officials on Friday moved to permanently shift responsibility for managing gray wolves to the states, proposing removal of the animals from the list of threatened and endangered species.
The U.S. Fish and Wildlife Service said the proposal comes after a comprehensive review has confirmed the successful recovery of gray wolves in the Western Great Lakes and Northern Rocky Mountains.
Biologists with the Interagency Grizzly Bear Study Team will be conducting grizzly bear research in Yellowstone National Park from June 3 through July 15 as part of ongoing monitoring of the activities and population of grizzly bears within the greater Yellowstone area. Team members will bait and trap bears at several sites within Yellowstone National Park, according to a statement released Friday by the Yellowstone public affairs office.
Brad Josephs, a naturalist interpreter specializing in bear biology and ecology, was guiding a trip in Alaska when he set up a GoPro camera and ended up capturing footage of a mother grizzly and her three-year-old son.
The decline in Yellowstone cutthroat trout in Yellowstone Lake has meant that anglers in Yellowstone National Park must release any of the native fish that are caught. Unfortunately, for the park’s osprey, catch-and-release fishing is not an option.
A Grand Teton National Park ranger will lead a bird-watching caravan on Saturday, May 11, in observance of International Migratory Bird Day. The public is invited to participate and to assist in conducting part of an annual North American bird count.
Some backcountry travelers in Yellowstone country are using electric fences to keep bears away from food and avoid conflicts with humans.
After nearly two decades since their reintroduction in Yellowstone National Park, population trends show that gray wolves are unlikely to thrive in sections of Wyoming outside the northwestern corner of the state.
Many wolf supporters remain dissatisfied with Wyoming’s so-called “dual status” management approach, which classifies wolves as trophy game in the area around Yellowstone and as predators elsewhere. But a state wildlife official said Thursday that policy changes won’t have much effect on wolf numbers across most of the state.
In a Grand Teton wildlife version of dogs vs. cats, a series of photos of two young mountain lions seeking refuge from five coyotes has been attracting plenty of attention after being shared online last week by National Elk Refuge staff members.
The photos taken by Lori Iverson, an outreach and visitor services specialist with the U.S. Fish and Wildlife Service, show a tense standoff, as the two juvenile mountain lions nervously crouch atop a rail fence. Coyotes can be seen in some of the photos watching anxiously.
As the continent’s ancient buffalo traces have become many of our major and minor highways, this unfortunately means that some bison never make it to their natal lands, but instead end up at the dump after being killed by speeding motorists. Six bison have already been struck and killed by motorists this season, five of these within 72 hours, and all at night.
Because of their dark color and eye placement, bison are extremely hard to see at night, often not until it is too late.
