We are a private, 501(c)(3) nonprofit organization whose mission is to fund projects that enhance Grand Teton National Park’s cultural, historic, and natural resources and to help others learn about and protect all that is special in the park.

Bighorn Sheep Population Monitoring: Bighorn sheep in the Teton Range persist as a small, high-elevation population that depends on limited summer forage to survive long winters and successfully reproduce. This project uses advanced field research and modeling to assess how much high-quality habitat the landscape can support, essential information to guiding conservation and recovery efforts.Bear Conservation: Among the most beloved of Grand Teton’s wildlife are black and grizzly bears, however increased human-bear interactions that threaten to disrupt the safety and longevity of these apex predators. The implementation of a number of bear research and conservation efforts ensures bears continue to flourish in healthy habitats.
