CEGL002123 Pinus ponderosa / Oryzopsis asperifolia Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Ponderosa Pine / Roughleaf Ricegrass Woodland
Colloquial Name: Ponderosa Pine / Roughleaf Ricegrass Woodland
Hierarchy Level: Association
Type Concept: This ponderosa pine community is found in the Black Hills of western South Dakota in the United States. Stands occur on sandy loams to silt loams on flat to gently sloping topography. The dominant tree is Pinus ponderosa. No other mature trees have been found in the canopy. There is a poorly developed shrub layer containing species such as Spiraea betulifolia and Symphoricarpos albus. The scattered herb layer is made up mostly of Oryzopsis asperifolia, with lesser amounts of Carex siccata, Galium boreale and Schizachne purpurascens.

Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This community is described on the basis of four stands in the Black Hills National Forest. This type was originally described as a phase of ~Pinus ponderosa / Symphoricarpos albus Forest (CEGL000203)$$ and recent analyses suggest that that is probably the best way to treat these stands, but see Marriott and Faber-Langendoen (2000).

Physiognomy and Structure: No Data Available
Floristics: This community is dominated by Pinus ponderosa in the overstory and Oryzopsis asperifolia in the herbaceous layer. Shrubs are scattered but readily apparent, particularly Spiraea betulifolia, Arctostaphylos uva-ursi, and Symphoricarpos albus. Carex siccata (= Carex foenea), Danthonia spicata, Galium boreale, and Schizachne purpurascens are present in the herb layer. In the stands in the Black Hills on which this description is based, shrubs had 10% cover and herbaceous species 20-25% cover (Hoffman and Alexander 1987). The invasive grass Poa pratensis is present in some stands of this type.
Dynamics: Fire likely played an important role in the dynamics of this woodland type. Fire scars are apparent on may of the older trees.
Environmental Description: This community has been found on flat to moderately sloping topography (2-24%) (Hoffman and Alexander 1987). The soils range from sandy loams to silt loams. This type is generally found on north aspects.
Geographic Range: This ponderosa pine community is found in the Black Hills of western South Dakota, in the United States.
