Cell(s):

  • Silver sagebrush/bluegrass flat or playa
  • Low sagebrush/bluebunch wheatgrass
  • Low sagebrush/Idaho fescue
 

The 1,548 ha Lake Ridge RNA lies on a broad plateau dissected by steep canyons, with Tim's Peak rising to the north. It is located southeast of Juntura, Malheur County, Oregon, in the sagebrush zone. The climate is characterized by cold, moist winters and hot, dry summers. Annual precipitation averages 20 to 25 cm. Elevation ranges from 1463 to 1554 m. Soils are rocky, shallow clays and clay loams over basalt. The RNA is dominated by low sagebrush (Artemisia arbuscula) plant communities with bluebunch wheatgrass (Pseudoroegneria spicata) or Idaho fescue (Festuca idahoensis). In addition to those two communities, the RNA protects a silver sagebrush/bluegrass (Artemisia cana/Poa) playa, and habitat for sage grouse, including several leks. A naturally occurring waterhole provides a perennial source of water. The area has been and is currently grazed lightly by cattle and sheep.
