Ecological site group description
Key Characteristics
- Marble Canyon (G)
- Soil at site is sedimentary or loamy.
- Site soils are typic aridic or within a 6-10" precipitation zone.
- Site is and/or located on a hill with slopes >15%.
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 on a hill with slopes >15%. Aspects tend toward Marble Canyon, and more generally, the northeast.
Climate
Site soils are typic aridic or within a 6-10" precipitation zone. No clear pattern exists in the seasonal timing of precipitation, generally driest in late spring.
Soil features
Parent material is limestone. Soils are loamy. Site consists of gently dipping shallow residuum weathered from sedimentary rocks eroded into steep cliff faces and canyons.
Vegetation dynamics
This plant community is a diverse shrubland with grasses and a few forbs. The dominant plants are: shadscale saltbush, black grama, Bigelow sagebrush, Torrey Mormon tea, and fourwing saltbush.
There is 2-10% plant basal cover and 10-45% plant canopy cover on the site. Cover is highly variable depending on amount of rock cover, slope and aspect.
The production amount varies depending upon how much rock outcrop and the aspect of the site. The maximum production amount of 350 pounds per acre may only occur in areas with the highest amount of soil and the least amount of rock outcrop.
