Western Ecology Working Group of...
Description:
This alliance is one of the most widespread wooded alliances in the western United States; there are currently over 50 plant associations in this alliance. The alliance is found throughout the western half of the U.S. and southwestern Canada, as well as the Trans-Pecos of Texas and the western portions of the Great Plains, such as in western Oklahoma and the Dakotas. Sites are dry/dry-mesic to xeric, and soils are generally well-drained and coarse-textured. Pinus ponderosa often dominates these woodlands, but codominant species may include Pseudotsuga menziesii, other Pinus species, and species of Juniperus, Abies, or Picea. The understory ranges from dense shrub or graminoid layers to barren rock. The associated plant species vary with changes in geography and environmental conditions. Associated trees include species of Pinus, Quercus, Juniperus, Abies, Pseudotsuga, Populus, and Picea. Shrubs can include species of Arctostaphylos, Artemisia, Cercocarpus, Ceanothus, Symphoricarpos, Physocarpus, Rosa, Purshia, and others. Important graminoids include species of Carex, Elymus, Poa, Festuca, Muhlenbergia, Piptochaetium, and many others.
