CEGL002194 Prosopis glandulosa / Bouteloua curtipendula Ruderal Shrubland

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Honey Mesquite / Sideoats Grama Ruderal Shrubland

Colloquial Name: Ruderal Honey Mesquite / Sideoats Grama Shrubland

Hierarchy Level:  Association

Type Concept: This shrubland association is currently only known from Lake Meredith National Recreation Area in Texas, and the following description is based on occurrences there. Additional information will be added as it becomes available. The composition and structure of this community are influenced by climate, soil (texture and depth) natural fire, invasion (seed source), and grazing pressure. Stands occur on gently sloping terrain, and soils are moderately deep and calcareous. This community is a shrubland with good cover of perennial grasses in the herb layer. Prosopis glandulosa is the dominant shrub with lesser amounts of Yucca glauca and Gutierrezia sarothrae. Total shrub canopy cover is usually approximately 25%. The major grass species is Bouteloua curtipendula, but significant amounts of Bouteloua gracilis and Sporobolus cryptandrus may also be present. Forbs provide no more than 10% of the total cover. The most common forbs are Tetraneuris scaposa, Chaetopappa ericoides, and Sphaeralcea coccinea.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: There is some question how the stands in Lake Meredith National Recreation Area, where Prosopis glandulosa has increased due to alteration of fire and grazing patterns, compare to stands farther south in Texas that are also assigned to this association. Data on this association are too limited to make the comparison at present.
