This ponderosa pine woodland is found in the Black Hills at 1310 to 1800 m (4300-5900 feet) elevation west to Colorado at 2560 to 2710 m (8400-8880 feet). This montane community is one of the more mesic of the ponderosa pine forests in the Black Hills and southern Rocky Mountains. Stands occur predominantly on north- to northwest-facing aspects but may also occur on eastern and southern aspects. Slopes tend to be moderate to steep but range from (1-49%). Soils are relatively deep, well-drained sandy loams from coarse colluvium. The overstory is dominated by <i>Pinus ponderosa</i> often with an admixture of <i>Pseudotsuga menziesii</i> and sometimes <i>Pinus flexilis</i> depending on seral stage. The canopy can be moderately open to closed. Sufficient light penetrates the canopy to allow the growth of a vigorous shrub layer (20-50% cover). There is a substantial shrub layer that grows to approximately 1 m tall. This stratum is dominated by <i>Physocarpus monogynus</i>. Other shrubs that occur in this community are <i>Acer glabrum, Amelanchier alnifolia, Mahonia repens, Prunus virginiana, Rosa acicularis, Arctostaphylos uva-ursi</i>, and <i>Symphoricarpos albus</i>. In the Rocky Mountains the tree canopy was more open, and <i>Symphoricarpos rotundifolius</i> may be present with up to 20% cover. The herbaceous layer is dominated by forbs and nonvascular plants. <i>Antennaria rosea, Cerastium arvense, Galium boreale, Pulsatilla patens</i>, and mosses and lichens are typically found in this community. Unvegetated surface is common in this association and is composed of needle litter and duff. |

The overstory of this community is dominated by <i>Pinus ponderosa</i>. There are lesser amounts of <i>Populus tremuloides, Betula papyrifera, Quercus macrocarpa, Juniperus scopulorum, Picea glauca, Pinus flexilis</i>, and <i>Pseudotsuga menziesii</i> successfully reproducing. The shrub layer is prominent and approximately 0.5-1.0 m tall. The most prevalent shrubs are <i>Amelanchier alnifolia, Symphoricarpos albus, Shepherdia canadensis, Mahonia repens, Spiraea betulifolia, Juniperus communis</i>, and <i>Prunus virginiana</i>. The herbaceous layer is also well-developed. Typical species found in this layer are <i>Achillea millefolium, Campanula rotundifolia, Balsamorhiza sagittata, Galium</i> spp., and <i>Euthamia occidentalis</i>. This ponderosa pine community type occurs in the mountains of the northwestern United States, from the eastern Cascades and northern Sierra Nevada to the Rocky Mountains and Black Hills. It is found on moderate, undulating slopes with loamy soils. Most stands are on slopes with more northerly aspects. Surface fires are a regular occurrence but regeneration after these events is rapid. |
