Native Forest/Vegetation Types

Dominated by Festuca scabrella (rough fescue), F. idahoensis (Idaho fescue), Danthonia parryi (Parry's oatgrass). Forbs include Geranium viscosissimum (sticky geranium), Anemone patens (prairie crocus), Lithospermum ruderale (wooly gromwell), Delphinium bicolor (low larkspur) and Balsamorhiza sagittata (balsam-root). Slopes and ravines may have scattered Populus.

Principal Biome/Ecoregion

Foothills Fescue grassland subregion. Mainly on glacial outwash and moraine deposits of the hills of the lower east slopes of the Rocky Mountains in Alberta. Soil is mainly dark brown and black chernozem. Climate is characterized by milder winters, frequent chinooks (temporary warm periods of a few days, resulting from reverse adiabatic warming as air moves downslope from the montane to grassland regions). Winter and summer percipitation and moisture availability are greater than in other nearby grassland ecoregions
