Name: Yucca glauca / Calamovilfa longifolia Shrub Grassland Reference: NatureServe Biotics 2019 Description: This soapweed yucca association is found on sandstone outcrops and sandy soils in the northern Great Plains of the United States. Soils are relatively deep (&gt;1 m), pure sands, with medium- to coarse-textured lower horizons. The substrate is well-drained but not xeric. The more broadly defined ~<i>Yucca glauca / Calamovilfa longifolia</i> Shrub Grassland (CEGL002675)$$ occurs on a broader range of ridgetops and upper slopes. Stands contain an open to moderately dense (at least 10% cover), low-shrub layer above a species-rich herbaceous layer. Dominance of the shrub layer by <i>Yucca glauca</i> is characteristic (average cover in six stands was 9.8%). <i>Artemisia tridentata ssp. wyomingensis</i> and <i>Artemisia cana ssp. cana</i> may be present but are sparse and contribute little cover. In the herbaceous layer, <i>Hesperostipa comata</i> and <i>Calamovilfa longifolia</i> codominate (16% cover and 8% cover, respectively), and <i>Bouteloua gracilis</i> and <i>Carex filifolia</i> often are present, but with low cover. Forbs are common but contribute little cover; <i>Artemisia frigida</i> has the highest constancy, but no forb is characteristic of the association. Litter covers up to about half of the ground surface, and most of the rest of the ground surface is bare soil.  Accession Code: urn:lsid:vegbank.org:commConcept:31583-{3692926E-F4E4-4B4F-8997-E1B1371681DF} Plot-observations of this Community Concept: 4
