Ecological site group description
Key Characteristics
- Chaco Mesa. This LRU subset is composed of Cretaceous materials, is generally above 1900 m in elevation, and does not drain directly into the San Juan River. The Chaco Mesa subset is further distinguished from the Bisti Lowlands in that the former receives more monsoonal moisture, harbors more warm-season grasses, and experiences a considerable amount of blowing sands.
- 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).
- Soils lack both significant salinity and sodicity.
- Soils lack one or both f the following at the surface: Strong or violent response to dilute HCl or ≥ 5% calcareous fragments.
- Sites with soils that have particle size classes of of sandy, coarse loamy, or coarser.
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
Upland landforms. Elevated terraces included; drainageway bottoms excluded. Flooding does not occur.
Soil features
