Name: Pinus ponderosa / (Ericameria nauseosa) / Achnatherum hymenoides Woodland Reference: NatureServe Biotics 2019 Description: This is a sparse ponderosa pine woodland found in the lower foothills zone of a portion of the southern Rocky Mountains. Stands occur on stabilized sand dunes in northern New Mexico (near Espanola) and in the Great Sand Dunes National Park and Preserve in southern Colorado on stabilized dunes. Elevations range from 1800-1920 m (5900-6300 feet) in New Mexico and 2453-2600 m (8040-8525 feet) in Colorado. Sites are gently sloping with southern and western aspects. Substrates are deep sands. Vegetation is characterized by an open to very open stand of large <i>Pinus ponderosa</i> (5-20% canopy cover). Sometimes <i>Juniperus monosperma</i> or <i>Juniperus scopulorum</i> are present. If present, the sparse to moderate shrub layer is composed of broad-leaved, deciduous species, especially <i>Ericameria nauseosa, Poliomintha incana</i>, and <i>Cercocarpus montanus</i>, with 1-10% cover. The herbaceous layer typically ranges from 5-20% cover but may be sparse (&lt;5% cover). Perennial grasses contributing the most cover include several species characteristic of sandy, dry substrates such as <i>Achnatherum hymenoides, Sporobolus contractus, Andropogon hallii</i>, and <i>Muhlenbergia pungens</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:30399-{DA0B4314-CE0C-4ECF-8853-8262D1C3FE05} Plot-observations of this Community Concept: 0
