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.
- Site occurs on landforms that are concave in one or more dimensions, and receive extra moisture from runoff, throughflow, or discharge in the landscape.
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
Bottoms of drainageways and swales.
Soil features
Soil properties for this group are variable. Salinity and sodicity range from slight to high. Flooding frequency is occasional. Soils well-to poorly-drained. This variability can be found within a single site/delineation, as well as between individual ecosites linked to this grouped concept.
