Name: Pinus ponderosa / Spiraea betulifolia Forest
Reference: Western Ecology Working Group of...
Description: This is a montane woodland or forest type found on mesic sites on the eastern flank of the Bighorn Mountains of north-central Wyoming at moderate elevations of 1650 to 1800 m (5400-5900 feet). This association occupies easterly slopes that are somewhat steep to steep (23-28°). Soils are sandy loams, derived from granitic parent materials. The overstory is formed by <i>Pinus ponderosa</i>, and the understory is a mixture of low shrubs, grasses, and forbs dominated by the low shrubs <i>Spiraea betulifolia</i> and (often) <i>Symphoricarpos albus</i>. Conspicuous by their absence are <i>Rhus trilobata, Physocarpus monogynus</i>, and <i>Pseudoroegneria spicata (= Elymus spicatus)</i>. The herbaceous layer is a mix of perennial forbs and graminoids, averaging 25-30% cover. Important grasses include <i>Festuca idahoensis, Leucopoa kingii (= Festuca kingii)</i>, and <i>Poa palustris</i>. Common forbs include <i>Balsamorhiza sagittata, Clematis columbiana, Galium boreale, Lupinus argenteus</i>, and <i>Maianthemum racemosum (= Smilacina racemosa)</i>. Nonvascular species are present, but not abundant. Sites supporting this association are more mesic than sites supporting ~<i>Pinus ponderosa / Pseudoroegneria spicata</i> Woodland (CEGL000865)$$ and ~<i>Pinus ponderosa / Festuca idahoensis</i> Woodland (CEGL000857)$$, and drier than ~<i>Pinus ponderosa / Physocarpus monogynus</i> Forest (CEGL000190)$$ sites.
