Name:
Juniperus scopulorum Woodland Alliance
Reference:
Western Ecology Working Group of...
Description:
This alliance includes woodlands dominated by Juniperus scopulorum, occurring in seven states from the northern and central Rocky Mountains, east to the Great Plains. Many associations in this alliance occur in the landscape above dry prairies and below communities dominated by Pinus ponderosa or Pseudotsuga menziesii. In southwestern North Dakota and western South Dakota, Juniperus scopulorum dominates low-stature woodlands, where associated species can include Pinus ponderosa, Pseudotsuga menziesii, Artemisia spp., Cercocarpus montanus, Purshia tridentata, Rhus trilobata, Bouteloua gracilis, Festuca idahoensis, Piptatherum micranthum (= Oryzopsis micrantha), Pseudoroegneria spicata, and Hesperostipa comata (= Stipa comata). This alliance is extremely limited in the southeastern United States, occurring in northwestern Texas in the escarpment area between the High Plains and Rolling Plains, where Juniperus scopulorum forms nearly pure stands on mesic slopes and in canyons. Juniperus scopulorum woodlands are typically found on gentle to steep, north-facing slopes, rock outcrops, and bluffs, and are best developed on calcareous soils. Soils are typically thin, stony, clay or clay loam, commonly with exposed bedrock. The soil parent material varies with community association but may be limestone, gneiss, sandstone, scoria, or shale.
