Small areas of the rough fescue prairie have also been des- cribed for southern Manitoba (Blood, 1966), northern Dakota (Crosby, 1965) and for southeastern Alberta (Moss and Campbell, 1947). The grasslands described in this paper are located to the north of the previously des- cribed northern limit of this association (Fi- gure 1). As is implied by the name, rough fescue {Festuca scabrella Torr) is the dominant grass species in this association (Looman, 1969). It is a bunch grass that generally grows on black (chernozemic) soils (Coupland, 1961). Distribution of this association is closely linked to the aspen parkland region which forms the transition between mixed prairie to the south and boreal forest to the north. Porcupine grass (Stipa spartea var. curtiseta Hitchc.) is a codominant, being gene- rally more prevalent in drier areas. The latter species also generally increases in dominance from north to south. Study Area Prince Albert National Park (total arae of 1,496 square miles) is located in central Sas- katchewan (mean latitude 53°5r). The un- dulating topographical rehef of the park has its origins in the pleistocene glaciation and sub- sequent erosions. Numerous hills, depressions and ridges account for the variety of plant communities within the park. About two- thirds of the northern part of the park is co- vered by dense, coniferous and mixed forests that exist on grey-wooded soils. Although the whole area is included in the mixed forest zone by Rowe (1959), the southern section of the park more closely resembles the aspen grove belt described by Moss (1955a). This is the transition zone between northern forests.
