Name: Pinus ponderosa / Symphoricarpos occidentalis Forest
Reference: Western Ecology Working Group of...
Description: This forest type is an important association in the foothills and lower montane slopes of the Little Rocky Mountains of north-central Montana where it occurs on all aspects of the rounded foothills and on warm aspects of moderate mountain slopes. Elevations range from 1040-1585 m (3400-5200 feet). Soils are loams or sandy loams derived primarily from limestone. Stands have an open to closed canopy of <i>Pinus ponderosa</i>. <i>Symphoricarpos occidentalis, Amelanchier alnifolia</i>, and <i>Prunus virginiana</i> dominate the relatively dense shrub layer. The herbaceous layer is composed of the perennial bunchgrass <i>Pseudoroegneria spicata</i> with a sparse but diverse assemblage of forbs including <i>Anemone multifida</i> and <i>Balsamorhiza sagittata</i>. These warm dry pine forests benefit from periodic ground fire that reduces over-stocking by killing seedling- and sapling-sized trees and lessens the risk of stand replacing crown fires.
