Blue Mountain

Blue Mountain Site

Location: Wheeler County, ~25 miles from Mitchell, OR
Land Management Agency: Bureau of Land Management Prineville District Office
SageSTEP Site Manager: Scott Shaff
Plots: Three 35-acre core plots (Control, Burn, Mechanical)
Elevation: 2600-2850 ft
Topography: 25% slope and NW aspect
Common Vegetation: Western Juniper, basin big sagebrush, bluebunch wheatgrass
Soils: Sandy loam, Frigid Typic Haploxerolls to Frigid Torriorthents derived from basalt 30-90 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: No grazing anticipated and so this site remains unfenced.
Treatments Implemented: Fall 2006. For more information about treatments, click here.

Western Juniper Woodland Prescribed Burn Subplot

Blue Mountain Site Yearly Photo Sequence

Prescribed burns were implemented at all of the SateSTEP woodland study sites. This treatment was used to help increase understanding of the relationship between plant communities, invasive species and fires. The Blue Mountain burn took place in the fall of 2007 after baseline data were collected. The images below show one of the prescribed burn subplots at the Blue Mountain site from 2007 to 2010.

2009 – 2 Years Post-Treatment

2010 – 3 Years Post-treatment

Western Juniper Woodland Chainsaw Subplot

Blue Mountain Site Yearly Photo Sequence

The chainsaw cut treatment was implemented at all SageSTEP woodland sites. All trees over 1/2-meter tall were cut with a chainsaw and left where they fell. The images below show one of the chainsaw subplots at the Blue Mountain site from 2007 to 2010. The chainsaw cut took place at Blue Mountain in the fall of 2007 after baseline data were collected.
