This site south of Rock Springs in Wyoming represents an intact sagebrush ecosystem. It has not been burned or invaded by exotic annual grasses. Undisturbed sagebrush steppe has bare ground between shrubs which helps to limit the spread of wildfire. When cheatgrass invades fires can grow larger.

The USGS provides science to understand, protect, restore, and solve problems in the world around us, and that includes interconnected communities of living things called ecosystems.

The grizzly bear distribution represents the estimated geographic extent of occupied range of the Yellowstone grizzly bear population. The images show a comparison of their estimated geographic extent, with a 3-fold increase from 1990 (23,361 km² or 9,020 mi²) to 2022 (70,101 km² or 27,066 mi²).
