Charley River Dall's Sheep Grazing Exclosures, Yukon-Charley Rivers National Preserve
National Park Service. Charley River Dall's Sheep Grazing Exclosures, Yukon-Charley Rivers National Preserve. 1994-1996. National Park Service
Little documentation exists for habitat use by Dall’s sheep, or the role sheep play in the disturbance and/or maintenance of sensitive vegetation associations within Yukon-Charley Rivers NP. To expand the knowledge base for Dall’s sheep habitat attributes, resource management personnel from Yukon-Charley Rivers NP installed 5 grazing exclosures at 4 locations within the upper Charley River basin to document sheep impacts on arctic steppe (alpine tundra) plant communities. The exclosures were installed in 1994 and 1 exclosure(s) were sampled in 1994, 1995, and 1996. Exclosure and control plots were sampled at each site using ocular estimation of percent cover for individual plant species.
