Ecological site group description
Key Characteristics
- San Juan River Corridor. This LRU subset consists of landforms which drain directly into the San Juan River. Elevations are mostly under 1900 meters. Stratigraphy is varied, ranging from the Mancos to the Nacimiento formations. This LRU subset is distinct from the rest of 35.4 in that it provides irrigation water. Thus, upland landforms which contribute significant water are included.
- Sites that occur on "upland", water-shedding landforms. Elevated terraces are included in this group.
- Soils are < 50 cm to lithic or paralithic contact (root-restrictive bedrock).
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
This site occurs on various water-shedding, bedrock-controlled landforms, including mesas, plateaus, structural benches, and escarpments in general.
Soil features
Soils are < 50 cm (20") to root-restrictive bedrock--either paralithic or lithic.
