Name: Fallugia paradoxa / Rockland Shrubland
Reference: Western Ecology Working Group of...
Description: This shrubland association is currently only known from El Malpais National Monument in New Mexico, and the following description is based on occurrences there. Additional information will be added as it becomes available. This association occurs between 2030 and 2420 m (6650-7950 feet) in elevation typically on rough and broken, gently rolling lava plateaus, but occasionally on moderate to steep sideslopes of volcano craters. Substrates are typically derived from McCarty's lavaflow, though occasionally from Hoya de Cibola flows, Twin Craters, or older lavaflows. Ground cover is dominated by lava rock or gravel. Trees are rare in this shrubland, and the shrub <i>Fallugia paradoxa</i> is the dominant species, occurring in every sampling location with an occasional maximum relative cover of up to 42%. Other shrub species, including <i>Holodiscus dumosus</i> and <i>Ericameria nauseosa</i>, also occur but less frequently and in less abundance. The herbaceous layer is characteristically sparse (about 2% total cover), though it rarely ranges as high as 20%; it is about equally divided between graminoids and forbs. <i>Schizachyrium scoparium</i> and <i>Elymus elymoides</i> are the most abundant grasses, although they occur infrequently. The most commonly occurring forb is <i>Heterotheca villosa</i>.
