State Lands/Kelly Parcel:In 2025, the Foundation supported the park in its decades-long effort to purchase the 640-acre Kelly parcel from the state of Wyoming. The Kelly parcel was the largest tract of unprotected land remaining within the boundaries of Grand Teton National Park. The elevated square-mile provides sweeping views of the Teton Range and includes critical habitat for numerous species of wildlife. The parcel is also located within a key migration corridor for pronghorn, elk, and mule deer. If the Kelly parcel was not permanently conserved as part of Grand Teton National Park, this inholding could have been developed, risking the loss of vital habitat in the Greater Yellowstone Ecosystemone of the last remaining, nearly intact temperate ecosystems on the planet. The permanent conservation of the Kelly parcel was a major conservation achievement for Grand Teton National Park and the Foundation in 2025.

That ratio is a good sign, not a scorecard. Plenty of great groups run leaner and lumpier. What matters is the extremes, and Grand Teton National Park Foundation is nowhere near one.
