Roberts Site

Location: Jefferson County, northwest of Rogers, ID
Land Management Agency: Bureau of Land Management Upper Snake River Field Office
SageSTEP Site Manager: Maggie Gray
Plots: Four 200-acre core plots (Control, Burn, Mechanical, Herbicide)
Elevation: 4800-4860 ft
Topography: 0-10% slopes of all aspects
Common Vegetation: Wyoming big sagebrush, Sandberg bluegrass, Indian ricegrass, bluebunch wheatgrass, and cheatgrass
Soils: Fine- to coarse-loamy, mixed

Representative Land Base: Several million acres in western and central Utah, southern Idaho, northern Nevada, and eastern Oregon
Grazing: Plots are located on an active grazing allotment, and will be fenced for the duration of the study to exclude livestock.

Wildfire Activity: Three of the four plots burned completely or partially in July 2010, but site will continue to be monitored for wildfire effects.
