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 have a combination of free carbonates and calcareous rock fragments at the surface. Strong or violent response to dilute HCl and ≥ 5% calcareous fragments.
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 upland, water-shedding landforms.
Soil features
The overriding property of the soils in this group is that they have abundant free carbonates (i.e. they will react strongly to dilute HCL) at the surface. Additionally, these soils are well-drained and >50 cm to root-restrictive layers.
