Name: Pinus edulis - Juniperus osteosperma / Mixed Shrubs Talus Woodland Reference: Western Ecology Working Group of... Description: This Colorado Plateau open woodland association is found in western Colorado and eastern Utah generally on lower slopes where talus and rockfalls accumulate. Sites can be between 1330 and 2290 m (4365-7500 feet) elevation. Slopes can be gentle to steep and of any aspect. The unvegetated ground surface is mostly bedrock and large and small rocks. Soils are rapidly drained. The parent material is talus rockfall. This woodland association can have sparse to moderate vegetation cover (4-61%) but is most often relatively sparse (<15% cover). The sparse to open tree canopy is 2-10 m tall. <i>Pinus edulis</i> and <i>Juniperus osteosperma</i> are the dominant canopy trees; either species can range from extremely low to moderate cover. The composition of the shrub stratum can be diverse, but cover is sparse to low. Common species are <i>Amelanchier utahensis, Artemisia bigelovii, Artemisia tridentata ssp. vaseyana, Cercocarpus montanus, Chrysothamnus viscidiflorus, Echinocereus triglochidiatus, Ephedra viridis, Eriogonum corymbosum, Fendlera rupicola, Gutierrezia sarothrae, Opuntia</i> spp., and <i>Rhus trilobata</i>. The herbaceous layer also provides sparse to low cover. Common graminoid species are <i>Achnatherum hymenoides, Aristida purpurea, Bromus tectorum, Elymus elymoides, Pleuraphis jamesii</i>, and <i>Poa fendleriana</i>. Common forbs are <i>Chamaesyce fendleri, Descurainia pinnata, Heterotheca villosa, Lepidium montanum</i>, and <i>Streptanthus cordatus</i>. Cryptogams are rare or absent on these active slopes.  Accession Code: VB.CC.31995.CEGL002328 Plot-observations of this Community Concept: 0
