Name: Pinus edulis - Juniperus osteosperma / Achnatherum hymenoides Woodland
Reference: Western Ecology Working Group of...
Description: This woodland association currently is documented from Canyonlands and Capitol Reef national parks in southeastern Utah. It occurs on basin floors, canyon bottoms, channels, and hillslopes. Sites are gentle (up to 4%), occur between 1506 and 1860 m (4946-6100 feet) elevation, and are oriented to southwestern and northwestern aspects. Parent materials include Moenkopi Formation (shale), Cedar Mesa sandstone, new alluvium, outcrops and basalt boulders. Soils are rapidly drained and fine-textured. Total vegetation cover generally does not exceed 50%. The open canopy consists of <i>Pinus edulis</i> and <i>Juniperus osteosperma</i> trees that range in cover from 5 to 50%, with a bunchgrass understory dominated by <i>Achnatherum hymenoides</i> that ranges in cover up to 25%. Shrubs do not have high enough cover to constitute a layer (<5% total cover) but are often present; common species include scattered individuals of <i>Cercocarpus montanus, Ephedra viridis, Artemisia</i> spp., <i>Ericameria nauseosa, Fraxinus anomala, Gutierrezia sarothrae, Amelanchier utahensis, Rhus aromatica</i>, and <i>Opuntia polyacantha</i>. The herbaceous layer is moderate in terms of species diversity and sparse to low in terms of cover. The most conspicuous associated graminoid is <i>Andropogon gerardii</i>.
