Provisional. A provisional ecological site description has undergone quality control and quality assurance review. It contains a working state and transition model and enough information to identify the ecological site.
Physiography
Landform and position are footslopes and backslopes of mountains, canyon sides, and mesas.
Climate
Winter summer moisture ratios range from 70:30 to 60:40. Late spring is usually the driest period, and early fall moisture can be sporadic. Summer rains fall from June through September.
Soil features
Soils are predominately very shallow to shallow but can be deep. Surface textures are clay loam, very gravelly clay loam, and very channery clay loam. Subsurface textures are clay loam, silty clay loam, and silty clay. Parent material is alluvium, residuum from shale, and sandstone.
Vegetation dynamics
The dominant aspect of this site is a mix of shrubs and grasses with widely scattered trees on slopes. Grasses include galleta, Indian ricegrass, and alkali sacaton. Shadscale is the major shrub with some Bigelow sagebrush, Greene's rabbitbrush, Stanbury cliffrose, and dwarf rabbitbrush. Overstory consists of scattered Utah junipers with an occasional Colorado pinyon present on the site.
