Name: Pinus edulis - Juniperus spp. / Fallugia paradoxa Woodland
Reference: NatureServe Biotics 2019
Description: This woodland association is currently only known from El Malpais National Monument in New Mexico. Additional information will be added as it becomes available. This association occurs between about 2025 and 2400 m (6620-7880 feet) elevation in on gentle slopes, gently rolling lava plateaus, and steep, moderately warm, southeasterly or northwesterly backslopes of cinder cones. Substrates of this lava-related association are derived from Bandera or McCarty's flows and cinders, and ground surface is predominantly lava rock and occasionally gravel. Tree canopies of this association range from very sparse (10% cover) to very open woodland (30% cover). Trees are often low and stunted. In a few areas, <i>Pinus edulis</i> is the only species found in sparse, savanna-like tree canopies of this association, but most areas are codominated by <i>Pinus edulis</i> and either <i>Juniperus monosperma</i> or <i>Juniperus scopulorum</i>. Saplings of <i>Juniperus</i> species are common; <i>Pinus edulis</i> saplings are uncommon or absent. In some locations, mature and sapling <i>Pinus ponderosa</i> are present, but never exceed 10% in total cover. The shrub layer ranges from absent to about 13%, with the diagnostic species <i>Fallugia paradoxa</i> dominant. Mesic shrubs such as <i>Forestiera pubescens, Holodiscus dumosus</i>, and <i>Rhus trilobata</i> are frequent associates, though cover is low. Herbaceous species cover is low (up to about 9%), either evenly divided between graminoids and forbs or with forbs dominant. Typically <i>Schizachyrium scoparium</i> dominates the graminoids, while <i>Heterotheca villosa</i> dominates the forbs.
