Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Alligator Juniper / Hairy Grama Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This diverse woodland savanna association is found in southern New Mexico with specific occurrences in the Animas, Organ, and Guadalupe mountains, and may occur elsewhere such as Trans-Pecos Texas, southeastern Arizona, and northern Mexico. It occurs from about 1650-1920 m (5400-6300 feet) on gentle hillslopes with southerly aspects. Soils are shallow and gravelly. The association is characterized by open stands of Juniperus deppeana, with Pinus edulis often present but subordinate. Quercus arizonica, Quercus grisea, or Quercus emoryi may be common tree associates. The overall plant diversity is high (85 plant species have been recorded from the type). Grass cover ranges from 10-30% and is variable in composition (23 species), but dominated by Bouteloua hirsuta. Forbs are diverse (32 species) and scattered.
