Name: Pinus ponderosa / Artemisia tridentata ssp. wyomingensis / Hesperostipa comata Woodland Reference: Western Ecology Working Group of... Description: These woodlands are open, sparse woodlands on isolated sand dunes and sandy flats. There are only two known occurrences, from the northern Great Basin, one in Oregon and one in California. They represent isolated Pinus ponderosa forests in sagebrush habitats, which are apparently Pleistocene relicts from a more mesic environment. The canopy is dominated by Pinus ponderosa at fairly low cover (averaging 4% canopy cover), making this a shrubland with scattered trees. On the margins, occasional Juniperus occidentalis individuals represent the only other tree found, and in patches these can be codominant. The majority of the shrub cover is from Artemisia tridentata ssp. wyomingensis and Chrysothamnus viscidiflorus. Dominant grasses are Hesperostipa comata (= Stipa comata), Achnatherum thurberianum (= Stipa thurberiana), Achnatherum hymenoides (= Oryzopsis hymenoides), Poa secunda, and Elymus elymoides. This is the only Pinus ponderosa association with Artemisia tridentata and Hesperostipa comata found on sandy habitats. Pinus ponderosa / Artemisia tridentata ssp. vaseyana / Poa nervosa Woodland (CEGL000180) has been described from higher elevations and silty soils.  Accession Code: VB.CC.23838.PINUSPONDEROSAA Plot-observations of this Community Concept: 0
