The Pryor Mountains provide desert like habitats unique in Montana and contribute significantly to the overall biological diversity of the state and the region. This study developed a classification of vegetation types on USDI BLM lands of the south Pryor Mountains, Carbon County, MT. Additionally, endemic and globally rare vegetation types were identified. Using a combination of two-way indicator species analysis (TWINSPAN) and detrended correspondence analysis (DCA) 33 vegetation types were identified among the 197 study plots. Comparisons with a "comprehensive" listing of vegetation from the western United States revealed that 9 of the types from the Pryor Mountains had not been reported from elsewhere and 14 are rare globally. This concentration of rare vegetation types, in combination with previously documented occurrences of rare plant species, highlight the significant biodiversity values of the Pryor Mountains.
