Name: Juniperus scopulorum / Schizachyrium scoparium Woodland Reference: NatureServe Biotics 2019 Description: This plant association is a "scarp woodland" known from shallow, rocky, calcareous, generally north-facing slopes of the Central Shortgrass Prairie (Ecoregion 27) of northern Colorado, southern Nebraska, and Wyoming between 1615-1680 m (5300-5500 feet). It may be considered a relict plant association of a formerly widespread plains woodland. As with most relicts, the composition of individual stands varies considerably. <i>Juniperus scopulorum</i> (40-45% cover) is always present in this association. A few stands consist of this species only. More commonly <i>Pinus flexilis</i> (0-20% cover) or <i>Pinus ponderosa</i> (0-20% cover), and often both, occur. The shrub layer in this association is generally poorly developed but may include <i>Rhus trilobata, Ribes cereum</i>, or <i>Prunus virginiana</i>. <i>Schizachyrium scoparium</i> dominates the herb layer of stands in good condition, with 15-30% cover. <i>Calamovilfa longifolia, Bouteloua curtipendula</i> (2-5% cover),and <i>Bouteloua gracilis</i> (5-15% cover) are often present and may be codominant. Fire suppression may increase the density of trees, while heavy grazing pressure may decrease the cover of <i>Schizachyrium scoparium</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:29659-{D6D02C72-138C-482C-8F0B-4511E1FFE087} Plot-observations of this Community Concept: 0
