Classification and Ordination of Alpine Plant Communities, Sheep Mountain, Lemhi Country, Idaho
The alpine vegetation in the immediate vicinity of Sheep Mountain, Lemhi Range, Lemhi County, Idaho, was investigated using data from field observations analyzed by the programs TWINSPAN and CANOCO (CCA). Percent cover of vegetation and environmental data were recorded for 77 plots. By computer anal...
