HODGKINSON AND ALFRED E. YOUNG Highlight: In Washington, rough fescue occurs primarily north of the 47O latitude Columbia to Newfoundland; from eastern and east of the Cascade Mountains. There are two large, well-represented areas. Other Washington and eastern Oregon to North locations are represented by small areas, some containing only scattered plants. Rough Dakota; and in Michigan, Wyoming, and fescue is very palatable and should be managed as the key species when it makes up Colorado (U.S. Dep.

The forage production yield decreased is grazing became heavier, and plant litter largely disappeared under the very heavy (90%) grazing. They also found that under the very heavy grazing, the char- acter of the soil changed. It became drier, and lighter in color and had higher soil temperatures. Moderate (50%) grazing maintained a high proportion of plants, encouraged early plant growth and, with the presence of litter and mulch, in- creased available moisture absorption. In another study, Johnston and MacDonald (1967) found close grazing in the winter did not kill plants or appreciably reduce their summer vigor. This research confirms observations in Washington. In Ferry County, rough fes- cue, managed in a deferred-rotation graz- ing system and with moderate grazing, showed an increase in size and vigor.
