Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Two-needle Pinyon - Utah Juniper / New Mexico Feathergrass Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This rare, open woodland association currently is documented only from Capitol Reef National Park in southeastern Utah; this summary is derived from plots sampled in the park in 1986. It occurs on low ridges with gentle slopes at 2012 m (6600 feet) elevation and a northeastern aspect. Parent materials include sandstones and shale. Soils are well-drained and fine-textured. Total vegetation cover does not exceed 50%. The vegetation is characterized by an open canopy of Pinus edulis and Juniperus osteosperma trees ranging in cover from 15 to 50% and an understory dominated by the bunchgrass Hesperostipa neomexicana with 10 to 25% cover. Shrubs are too sparse to form a layer (<5% total cover), but scattered individuals of Chrysothamnus viscidiflorus and Opuntia spp. occur. The herbaceous layer provides low cover. Commonly associated graminoids are predominantly bunchgrasses, including Achnatherum hymenoides and Hesperostipa comata. Forbs provide sparse to low cover.
