In a world where wild, open spaces are rapidly disappearing, Wyoming is unique.

We still have rugged, awe-inspiring public lands to explore. We have vast stretches of undeveloped land where mule deer, elk, and pronghorn migrate freely and where nearly half of the world’s Greater sage-grouse live, and we have rivers and streams that support world-class native trout. The Wyoming Outdoor Council works to ensure the sustainability of wildlife habitat today and far into the future.


Elk, mule deer, pronghorn, and dozens of other species need intact habitat to survive. That’s why we advocate for crucial big game winter range and seasonal habitats such as migration corridors and stopover sites. Working with partners, we’re seeking long-term safeguards for the 150-mile Red Desert to Hoback mule deer migration corridor—the world’s longest. We’re also urging the Wyoming Game and Fish Department to designate and protect other known corridors around the state.

Since last September, we’ve seen a wave of parcels offered in critical mule deer habitat, including in migration corridors and in winter range. Upcoming state and federal sales continue this trend, and if past lease sales are any indication, many of these parcels will go for as little as $2 per acre. Time is running out.

We must act now to defend this world-renowned corridor and other habitat big game herds rely on for survival. The majority of Wyoming citizens do not support oil and gas leasing inside migration corridors. The fact is, if we care about the future of our mule deer herds, we should not be leasing here today.

The increasing body of science from research in Wyoming shows that mule deer stick to their migration routes more than other big game do, and that they cannot adapt their migration strategy to avoid energy infrastructure and other human disturbance.

And once migrations are disrupted they may never be restored. Once we fragment and develop stopover sites and winter range, we can’t make more of it. If we want to ensure Wyoming’s mule deer herds stay viable well into the future, we need to challenge oil and gas leasing in their most vital habitats now.

Multiple use of our public lands means identifying the highest and best uses on any given acre. It means making informed decisions about where oil and gas development should happen and where it shouldn’t. The science is clear: if we value Wyoming’s mule deer, their migration corridors should not be leased.

Wyomingites need to come together to stand up for our muleys.
Let Governor Gordon know you are concerned. You can email him at governor@wyo.gov.

In late October, the Select Federal Natural Resource Management Committee voted to advance an anti-wildlife bill — despite overwhelming and diverse public comment asking the state legislature not to interfere with migration corridors and to support Gov. Gordon’s forthcoming executive order based on recommendations from a citizen advisory group.

This means we’ll need your help to defeat this bill during the 2020 legislative session — stay tuned and read more below.

Wyoming is the biological and political epicenter of both the historic effort to protect the Greater Sage-grouse and its habitat, and the current effort to defend these conservation measures. With its tens of millions of acres of sagebrush habitat, Wyoming is home to almost 40 percent of the world’s Greater sage-grouse.

Several years ago, Wyoming charted a collaborative and science-based path forward—identifying sage-grouse “core areas” where development would be limited. Neighboring states largely adopted Wyoming’s model, as did the Bureau of Land Management. These actions averted listing of the bird under the Endangered Species Act.

But this presidential administration’s stated priority of “energy dominance”—which has resulted in the BLM fast-tracking leases on public lands, increased drilling in sage-grouse core habitat, and a lack of agency accountability—greatly threatens that habitat, along with the hundreds of species that rely on it. The Outdoor Council is playing a leading role to ensure conservation measures remain in place.


Much of our work results in sustained or better habitat for fish. From finding solutions to avert 136-gas wells from being drilled at the headwaters of the wild and scenic Hoback River, to working with anglers in Saratoga to address municipal waste in the North Platte, a blue-ribbon fishery, to efforts with Brooks Lake Lodge to clean up its antiquated sewage lagoons to help ensure we never see a repeat of the fish die-off that happened in 2008 downstream, the Outdoor Council is a leading voice for clean water and healthy fisheries.

Today we’re working to ensure proposed oil and gas development in Colorado River cutthroat trout habitat in the South Cottonwood drainage of the Wyoming Range only goes forward with rigorous safeguards.
