Name: Pinus ponderosa / Poa fendleriana Woodland
Reference: NatureServe Biotics 2019
Description: This woodland association is currently known from El Malpais National Monument in New Mexico, and Grand Canyon-Parashant National Monument and Grand Canyon National Park in Arizona. This association occurs between 1900 and 2537 m (6250-8323 feet) in elevation on moderately steep slopes of volcanic cinder cones, plateaus, and gentle sideslopes across all aspects. The ground surface is dominated by pumice gravels and scattered grasses and litter at El Malpais and predominantly litter in Arizona. These open-canopied (10-25% cover) tall woodlands are dominated by <i>Pinus ponderosa</i> with short-statured conifers such as <i>Juniperus scopulorum</i> or <i>Pinus edulis</i> sometimes present in the subcanopy. Shrubs are few and sparse, although <i>Quercus gambelii, Mahonia repens</i>, and <i>Ceanothus fendleri</i> are common, and the understory is characterized by scattered bunchgrasses. <i>Poa fendleriana</i> is the dominant and can be well-represented to abundant, and <i>Koeleria macrantha</i> is common along with deer sedges (e.g., <i>Carex geophila</i> and <i>Carex rossii</i>). Forbs are scattered and variable and may include <i>Achillea millefolium, Allium cernuum, Antennaria parvifolia, Artemisia dracunculus, Artemisia ludoviciana, Bahia dissecta, Glandularia bipinnatifida, Hymenopappus filifolius, Hymenoxys richardsonii, Lactuca serriola, Lithospermum multiflorum</i>, and <i>Mentzelia multiflora var. integra</i>.
