Name: Pinus ponderosa / Artemisia tridentata ssp. vaseyana Woodland Reference: NatureServe Biotics 2019 Description: This open ponderosa pine woodland is described from the southern Rocky Mountains on sites at 2200 to 2865 m (7215-9400 feet) elevation on dry, moderate to somewhat steep slopes with southerly to easterly aspects. Stands often occur adjacent to sagebrush shrublands. Soils are well-drained or rapidly drained sandy loams and loamy sands derived from granite or sandstone. The vegetation is characterized by an open tree canopy (10-30% cover) dominated by <i>Pinus ponderosa</i> with a moderately dense short-shrub layer dominated by <i>Artemisia tridentata ssp. vaseyana</i> (10-30% cover). Tree canopy may have low cover of <i>Pinus edulis, Juniperus osteosperma</i>, or <i>Juniperus scopulorum</i>. The shrub layer may be diverse. Associated shrubs and dwarf-shrubs may include <i>Amelanchier utahensis, Artemisia frigida, Chrysothamnus viscidiflorus, Ericameria nauseosa, Gutierrezia sarothrae, Mahonia repens, Opuntia fragilis, Paxistima myrsinites, Purshia tridentata, Ribes cereum</i>, and <i>Symphoricarpos oreophilus</i>, usually with &lt;5% cover each. The herbaceous layer ranges from sparse to moderately dense and is typically dominated by graminoids (to 40% cover). Common associates include <i>Achnatherum hymenoides, Bouteloua gracilis, Elymus</i> spp., <i>Hesperostipa comata, Koeleria macrantha, Muhlenbergia montana, Poa secunda</i>, and introduced species <i>Bromus inermis, Bromus tectorum</i>, and <i>Poa pratensis</i>. Forbs are less significant and few species contribute &gt;1% cover.  Accession Code: urn:lsid:vegbank.org:commConcept:31698-{05E2047D-A99E-40FF-B869-B307CD119CA7} Plot-observations of this Community Concept: 0
