Birch Creek soil and landscape
A soil profile and landscape of Birch Creek soil in Idaho. The Birchcreek series consists of moderately deep, well drained soils that formed in alluvium, colluvium, and residuum derived from mica schist and quartzite or from andesite. Birchcreek soils are on mountains. Slopes are 4 to 55 percent. The mean annual precipitation is about 360 mm and the mean annual temperature is about 5.6 degrees C.
TAXONOMIC CLASS: Clayey-skeletal, smectitic, frigid Typic Argixerolls
Soil moisture: Usually moist in the moisture control section in winter and spring, dry in summer and fall; xeric moisture regime that borders on aridic.
Mean annual soil temperature: 6 to 8 degrees C.
Mollic epipedon thickness: 25 to 46 cm; includes the Bt1 and Bt2 horizons.
Depth to bedrock: 50 to 100 cm to a lithic contact.
Reaction: Neutral or slightly alkaline.
Particle-size control section - Clay content: Averages 40 to 50 percent.
Rock fragments: 45 to 60 percent, mainly cobbles and gravel in the upper part and cobbles and stones in the lower part. Lithology of fragments is metamorphic rocks such as mica schist and quartzite or volcanic rock such as andesite.
USE AND VEGETATION: Birchcreek soils are used for livestock grazing. The vegetation is mountain big sagebrush, low sagebrush, bluebunch wheatgrass, and Idaho fescue. Some areas support stands of singleleaf pinyon and Utah juniper.
DISTRIBUTION AND EXTENT: Southern Idaho and eastern Nevada. These soils are moderately extensive. The original series concept is in MLRA 25 in Idaho, while the main acreage occurs in MLRA 28B in Nevada.
