Castlehead Site

Location: Owyhee County, ID, ~60 miles from Jordan Valley, OR
Land Management Agency: Bureau of Land Management Owyhee Field Office
SageSTEP Site Manager: Scott Shaff
Plots: Three 35 to 60-acre core plots (Control, Burn, Mechanical) and two extensive plots (2545-acre control and 3200-acre burn)
Elevation: 5000-6200 ft
Topography: 5-8% slopes, SE aspect (burn and mechanical plots), W aspect (control plot)
Common Vegetation: Western Juniper, mountain big sagebrush, low sagebrush, Idaho fescue, Sandberg bluegrass
Soils: Fine loamy, mixed
Fire Regime: Historically frequent to moderately frequent (10-70 years), low intensity to mixed severity fires. Woodland invasion suggests that the majority of these communities have not burned since the late 1800’s. As woodlands gain dominance, the fire regime shifts to infrequent, high-intensity fires.
Representative Land Base: Several million acres in eastern OR, northeastern CA, southwestern ID, and northwestern NV
Grazing: Plots are located on an active grazing allotment.
Treatment Schedule: This site was partially burned by a wildfire in the summer of 2007. A prescribed burn on the remainder of the plot was attempted in fall 2007 but was unsuccessful due to weather. For more information about treatments, click here.
