CEGL001753 Bouteloua eriopoda - Hesperostipa neomexicana Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Black Grama - New Mexico Feathergrass Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This is a major community of the San Andres, San Augustine, and Oscura mountains of New Mexico with some occurrences on Chupadera Mesa. Stands occur mostly on cool north-facing, steep-sloped escarpments and on smooth dip slopes at elevations from 1490 to 2090 m (4900-6850 feet). However, some are found on the upper piedmonts that lead west from the Oscura Mountains and within upland valleys of the San Andres Mountains. Rock and gravel surfaces are dominant and parent materials consist of limestone and occasionally sandstone. Soils are predominantly shallow and are mostly medium- to coarse-textured loams and sandy loams. This grassland is characterized by well-represented to abundant Hesperostipa neomexicana with Bouteloua eriopoda as the codominant. Other common grasses include Bouteloua hirsuta, Bouteloua gracilis, and Bouteloua curtipendula that can be present, but clearly subordinate. The shrub layer consists of many different species (39), but they are widely scattered and variable. The most common are Yucca baccata, Opuntia phaeacantha, and Dalea formosa. The forbs are highly diverse (63 species) and variable with Melampodium leucanthum being the most constant species. Juniperus monosperma is present in some stands but in very low densities.
