A new study finds that hunting season does not trigger untimely mule deer migration in Wyoming.

A new study by the Wyoming Cooperative Fish and Wildlife Research Unit at the University of Wyoming found mule deer migration is negatively impacted by global warming induced droughts.

Researchers from Western Ecosystems Technology and the University of Wyoming have found how much land development a deer can actually handle in a recent study.

The last of five installments of funding totaling almost $2.5 million was approved by the Wyoming Game and Fish Commission recently. The $560,000 has been distributed over the past five years to support the Statewide Mule Deer Initiative.

Reducing speed limits might sound like a cheap, easy way to keep both human and wildlife safe on Wyoming roads.

Biologists with the Wyoming Game and Fish Department in Gillette recently collared 35 mule deer does in the Rochelle Hills area southeast of Wright.

The Wyoming Game and Fish Department wrapped up the first part of its Upper Powder River Mule Deer herd habitat project. It's hoping to improve mule deer habitat in the southern Bighorn Mountains.

The Wyoming Game and Fish Commission has approved spending $1.25 million to build two wildlife underpasses in western Wyoming on Highway 189. Game and Fish's Sara DiRienzo said Wyoming Department of Transportation and other organizations are partnering on the projects because of the high number of wildlife crashes on a 28 mile stretch of road.

University of Wyoming researchers are trying to find out if predators are affecting the low population of mule deer near Rock Springs. Statewide, mule deer have declined by 31 percent since 1991. As part of the project, researchers put tracking collars on 30 coyotes and have been watching their behavior to see if their behavior changes during peak times when fawns are born. 

Wyoming is leading the trend on protecting wildlife migration routes across the region, but the state's latest move to add two more migration routes is being held up by a letter from a coalition of industries, including oil and gas, mining and livestock interests. Jim Magagna is with the Wyoming Stock Growers Association.

A new study conducted by a global wild cat conservation organization finds that a mountain lions' prey differs by age.

The Bureau of Land Management ended the first quarterly oil and gas lease sale in Wyoming. It's offering nearly 150,000 acres-62 percent of that is on core sage grouse habitat.

This winter, our region has seen heavy snowfall. That can be tough on wildlife.

Two bills are currently moving through the legislature that would give the Wyoming Game and Fish Department more flexibility to manage the collecting of antlers on the landscape. Right now, people can collect them anytime between January 1 and May 1 in designated areas of the state.

An iconic big game migration corridor in western Wyoming will avoid oil and gas development for the time being. Interior Department Secretary Ryan Zinke and Governor Matt Mead announced Tuesday the deferral of thousands of leases within the area and stipulations for some development. 

After walking the usual migration route from the Red Desert to Hoback Junction near Jackson, Mule Deer Doe #255 kept going to Island Park, Idaho, traveling a total distance of 242 miles. That's 92 miles farther than the known-longest mule deer migration route. All summer, scientists waited to see if she’d migrate back or if she had just joined a different herd. 

Last year, the Wyoming Range mule deer herd died in incredibly high numbers because of record-breaking snow depths. That same snow, however, meant extra deep grasses for the surviving deer, according to Wyoming Game and Fish Department biologist Gary Fralick.

Fralick is part of the Wyoming Range Mule Deer Project’s effort to understand why the population has been declining there. He said the 2017 winterkill was the worst since the 1980s, but the hope is that this year’s (so-far) mild winter might mean the start of a recovery.

Mule deer can migrate a little bit easier starting this year thanks to new fencing along their migration route. Wyoming’s Game and Fish Department replaced old livestock fencing this summer with the help of several partners including the Wyoming Wildlife and Natural Resource Trust Fund, Upper Green Muley Fanatics, Jonah Energy, and the Conservation Fund.

Mule deer migrate from Hoback, south of Jackson, to the Red Desert every year. It allows them to get the best vegetation and find the safest areas to raise fawns.

A Wyoming researcher recently discovered that mule deer continue to avoid areas developed by oil and gas companies, after more than fifteen years.

Biologist Hall Sawyer has been studying a herd near Pinedale since 2000, just as more oil and gas wells were starting to appear on the landscape. Because the deer have steered clear of development, Sawyer says they have had a smaller winter range. The herd’s population started declining in just two years, and by now it has shrunk by 40%.

Researchers studying mule deer in the Wyoming Range in western Wyoming say that all the fawns they radio-collared last year died in this year's harsh winter and that 40 percent of the female does also perished. University of Wyoming wildlife biologist Kevin Montieth said usually only 15 percent of does die in winterkills. 

Wildlife in the far western portion of Wyoming did not fare so well this winter. The harsh weather was especially hard on deer.  

Doug Brimeyer with the Wyoming Game and Fish Department said the combination of heavy snow accumulation and extreme temperatures took a toll on deer and antelope in the western outreaches of the state. Those conditions ultimately kept animals from accessing good forage, and as a result, Brimeyer said, wildlife quickly used up their fat reserves.

Wildlife advocates are among those concerned about the presidential executive order to reverse the Clean Power Act and lift a moratorium on new coal leases. The National Wildlife Federation says migrating mule deer and pronghorn are suffering from the effects of energy development and benefited from federal regulations of the industry. 

Tribal Partnerships Director Garrit Voggesser says market forces will likely limit how many coal jobs actually return to Wyoming, but he says dwindling wildlife will hurt the state’s economy.

A new case of Chronic Wasting Disease (CWD) was found in a harvested mule deer buck 12 miles outside of Dubois this week. It was found in hunting area 128 and neighbors area 171 where CWD had been found earlier this year. According to Wyoming Game and Fish Wildlife supervisor in Lander, Jason Hunter, it’s not surprising that the disease has spread. 

Wyoming Game and Fish officials report the state’s mule deer population is growing because of good moisture during the spring and early summer the past three years. Officials said this moisture helps grow the grasses mule deer need to eat coming out of winter.

Ian Tator of the Wyoming Game and Fish Department said because of good rainfall, the number of fawns born the past two years is more than enough to help the mule deer population grow.
