Name: Pinus edulis / Rockland Woodland
Reference: NatureServe Biotics 2019
Description: This pinyon pine woodland association occurs in Arizona, Colorado and New Mexico. This description is based on information from Great Sand Dunes National Park and Preserve in Colorado. Additional global information will be added as it becomes available. This woodland is known from colluvial slopes and ridges between 2765 and 2885 m in elevation. Bedrock outcrops are typically present with 20-40% ground cover. Combined with large rocks and gravel, they make up at least 50% of the ground cover. Bare soil can also be prevalent, leaving litter to cover between 10-25% of the ground surface. Slopes range from 40° on steep colluvial slopes to 12° on rocky ridgetops. Substrates tend to be loose and actively eroding. Soils are rapidly to well-drained loamy sand. <i>Pinus edulis</i> forms an open to moderately dense canopy with 10-50% cover. The understory is generally sparse, with no stratum exceeding 10% cover. <i>Cercocarpus montanus</i> may be present, but does not form a shrub layer. Characteristic species include <i>Juniperus scopulorum, Ribes cereum, Bouteloua gracilis, Muhlenbergia montana, Opuntia polyacantha</i>, and <i>Heterotheca villosa</i>.
