Land Management Agency:
Bureau of Land Management Upper Snake River Field Office
SageSTEP Site Manager: Jeff Burnham
Plots: Four 200-acre core plots (Control, Burn, Mechanical, Herbicide)
Elevation: 4800-4860 ft.

Common Vegetation: Wyoming big sagebrush, Sandberg bluegrass, Indian ricegrass, bluebunch wheatgrass, and cheatgrass.
