Carney Ranch forms the most important piece of the Path of the Pronghorn’s “Funnel Bottleneck” for pronghorn antelope migrating from as far north as Grand Teton National Park. The property features the only bottleneck occurring on private lands—and the most vulnerable.

In 2010, the Fund announced the completion of a conservation easement that protects the northernmost 2,400 acres of Carney Ranch, located at the head of the Upper Green River Valley in Sublette County, by preventing future development of the land and ensuring its sound management. We purchased the easement from the Carney family, which will continue to own the land and operate it as a working ranch as it has since 1963.

“This project protects the pronghorn and a working cattle ranch—two icons of the American West,” said Luke Lynch, Wyoming state director for the Fund. “The Carney Ranch and the entire Upper Green River Valley boast some of the highest quality habitat and open space in the Greater Yellowstone Ecosystem, and we thank the numerous partners for continuing to support the conservation of this important landscape for future generations. The Carney family made a significant donation to make this possible—we applaud the three generations of family members for their major commitment to conservation.”

We purchased the easement using funding from the Acres for America program, a partnership established between Walmart Stores, Inc. and the National Fish and Wildlife Foundation. Jonah Interagency Office (JIO), Wyoming Landscape Conservation Initiative, the Wyoming Wildlife & Natural Resources Trust and The Nature Conservancy, through a grant from the Doris Duke Charitable Foundation, provided additional funding for the easement. In addition, the landowners made a significant donation to the project.
