COMPETING SERIES: There are no competing series
GEOGRAPHIC SETTING: Taine soils are on hills and mountains at elevations of 4,000 to 5,200 feet. They formed in alluvium from basalt. Slopes range from 12 to 35 percent. The mean annual precipitation is 10 to 14 inches. The mean annual air temperature is about 52 to 55 degrees F. The frost-free period is 200 to 230 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Birdsbeak, Milok and Pastern soils. Birdsbeak soils are less than 20 inches to a paralithic contact. Milok soils are very deep. Pastern soils are shallow to a hardpan.
DRAINAGE AND PERMEABILITY: Well drained; medium to high runoff; slow permeability.
USE AND VEGETATION: Taine soils are used mainly for livestock grazing, wildlife habitat and recreation. Vegetation is Utah juniper and singleleaf pinyon with an understory of banana yucca, broom snakeweed, sideoats grama, galleta, slim tridens, and blue grama.
DISTRIBUTION AND EXTENT: Northwestern Arizona. This series is moderately extensive. MLRA is 38.
