Name: Hesperostipa neomexicana - Bouteloua curtipendula Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: This association has been documented primarily in central New Mexico, but likely extends into the Southern Shortgrass Prairie of eastern New Mexico. It is specifically known from the foothills of the Sierra Oscura, San Andres Mountains, and Otero Mesa. This association primarily occurs on steep colluvial slopes and on the mid and upper portions of smooth dip slopes with warm to moderate aspects. Stands also occur within upland valleys that dissect the eastern slopes of the Sierra Oscura. Elevations are moderate to high at 1400-2200 m (4600-7200 feet). Substrates are generally Paleozoic limestones and/or sandstones, but occasionally include igneous granitic rocks. The ground surfaces are generally gravelly, with scattered rocks and little exposed soil. Surface soils range from sandy loams to clays. With depth, soils often have well-developed caliche layers of secondary calcium carbonate accumulation. This Plains-Mesa-Foothill grassland is characterized by a luxuriant cover of the cool-season grass Hesperostipa neomexicana (= Stipa neomexicana), along with the warm-season grass Bouteloua curtipendula. The grass layer also includes other Bouteloua and Aristida spp. that are present in over half the stands. The shrub layer seldom exceeds 5% cover and consists mostly of low-growing dwarf species such as Parthenium incanum, Yucca baccata, Opuntia phaeacantha and Dalea formosa. The forb layer is minimal, with Melampodium leucanthum being the most constant species.
