Elevation: 1700 ft
Topography: 0–10 % slope with a Southern aspect
Common Vegetation: Bluebunch wheatgrass, Wyoming big sagebrush, Needle and Thread, Sandberg’s bluegrass
Soils: Strat-Tubspring-Skaha complex
Fire Regime: The Wyoming big sagebrush type is the driest of the sagebrush steppe communities and historically had a fire return interval of approximately 50-100 years The introduction of cheatgrass into the sagebrush grassland communities has increased fine fuels and reduced the fire return interval to less than 10 years.
Representative Land Base: This site is representative of sage steppe ecosystem of eastern Washington.
Grazing: This site is actively grazed and will be fenced for the duration of the study to exclude livestock.
Treatment Schedule: Treatments were implemented in fall 2008 except for the burn, which is planned for 2009. For more information about treatments, click here.
