Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Mexican Pinyon - Gray Oak - Drooping Juniper / Mountain Sage / Bullgrass Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This community occurs at moderate to high elevations in the Chisos Mountains, in relatively moist situations. The open canopy consists of 4- to 15-m Pinus cembroides, Quercus grisea, Juniperus deppeana, Juniperus flaccida, and Juniperus coahuilensis. The shrub layer is open, and consists of Agave havardiana, Dasylirion leiophyllum, Nolina erumpens, and Salvia regla. The herbaceous stratum is dominated by Muhlenbergia emersleyi, but is diverse and also includes Bothriochloa barbinodis, Lycurus sp., Muhlenbergia rigida, Eragrostis sp., and Schizachyrium scoparium var. scoparium.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Juniperus flaccida and Salvia regla as nominal species restrict this association to the Big Bend area (at least in the United States). This is warranted by substantial floristic distinction.
