Ecological site group description
Key Characteristics
- Grand Canyon (D)
- Site parent material is volcanic or clayey.
- Site soils are ustic aridic or within a 10-14" precipitation zone.
- Site is and/or located in a wash.
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
Site is and/or located in a wash/bottom. Physiography is complex.
Climate
Site soils are ustic aridic or within a 10-14" precipitation zone. Precipitation comes monsoonal patterns during months of July, August, and September, and is supplemented by winter storm patterns from November through March.
Soil features
Parent material is basalt or andesite. Soils are clayey. Site consists of broad alluvial deposits in washes, streams or fans, often deep.
Vegetation dynamics
This site supports a grassland interspersed with small amounts of shrubs. In the original plant community, there is a mixture of both cool and warm season grasses.
Plants most likely to invade or increase on this site are big sagebrush, rabbitbrush, broom snakeweed, mat muhly, and annuals. Continuous winter and spring grazing use will eliminate the cool season mid-grasses.
