CEGL003877 Prosopis glandulosa var. glandulosa / Bouteloua gracilis - Bouteloua dactyloides Ruderal Shrubland

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Honey Mesquite / Blue Grama - Buffalograss Ruderal Shrubland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This shrubland association is found in Oklahoma and Texas and possibly New Mexico. It is currently only described from Lake Meredith National Recreation Area in Texas. Additional global information will be added as it becomes available. The composition and structure of this community are influenced by climate, soil (depth and texture) natural fire, invasion (seed source), and grazing pressure. It occurs on deep, medium- to fine-textured soils on nearly level to gently sloping terrain. It is typically found on mid to upper slopes or high level areas. This community is a shrubland dominated by Prosopis glandulosa with canopy cover of >25%. The shrubs may be short or tall with the range being generally from 1.5-3 m in height. Prosopis glandulosa may be single-stemmed or multi-stemmed and is a deep-rooted, very competitive plant. The ground layer is dominated by short grasses with Bouteloua gracilis being the most prevalent species. Sporobolus cryptandrus is usually present but rarely abundant. Forbs tend to be few and are dependent on spring moisture. The more common forbs include Sphaeralcea coccinea, Ratibida columnifera, Thelesperma filifolium, Chaetopappa ericoides, and Amphiachyris dracunculoides.
