|The dominant grass in the Cypress Hills is rough fescue (Festuca scabrella).
Rough fescue is an erect, densely tuffed perennial that often has short rhizomoes. Rough fescue can be located throughout the
Canadian prairies, usually on north-facing (cooler) slopes. It is common, however, in the Cypress Hills, the Wood Mountain, the Parklands, and the foothills of the Rocky Mountains.
