Devine Ridge

Devine Ridge Site

Location: Harney County, near Burns, OR (~25 miles)
Land Management Agency: Bureau of Land Management Burns District Office
SageSTEP Site Manager: Scott Shaff
Plots: Three 30 to 60-acre core plots (Control, Burn, Mechanical)
Elevation: 4800-5200 ft
Topography: 5-8% slopes, SE aspect (burn and mechanical plots), W aspect (control plot)
Common Vegetation: Western Juniper, mountain big sagebrush, Idaho fescue
Soils: Coarse grained sandy loam Frigid Torriorthents derived from basalt, 30-60 cm deep
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 and will be fenced for the duration of this study.
Treatments Implemented: Fall 2007. For more information about treatments, click here.

Devine Ridge Site Yearly Photo Sequence

All of the SageSTEP study sites have a control plot to account for variations that are not related to treatment, such as yearly climatic variation. The images below show one of the subplots in the Devine Ridge control plot from 2007 to 2010.
