Ecological site group description
Key Characteristics
- Bisti Lowlands. This LRU subset is composed of Cretaceous materials, and is generally below 1900 m in elevation. The Bisti Lowanads subset is further distinguished from Chaco Mesa in that the former receives less monsoonal moisture, harbors less warm-season grass, and experiences low amounts 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 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
Various water-shedding, upland landforms, including elevated terraces. Drainageways are excluded from the Sandy ESG concept. Also excluded are soils with moderate to high salinity and or sodicity, and those with abundant free carbonates at the surface.
Soil features
Soils have particle size family classes of coarse-loamy and coarser.
