普赖尔山脉提供了蒙大拿州独特的沙漠般的栖息地，并为该州和该地区的整体生物多样性做出了重大贡献。本研究开发了一个分类的USDI土地管理局土地在南普赖尔山脉，碳县，蒙大拿州的植被类型。此外，还确定了地方性和全球稀有的植被类型。采用双向指示种分析（TWINSPAN）和去趋势对应分析（DCA）相结合的方法，在197个样地中识别出33个植被类型。与美国西部植被类型的“综合”列表进行比较，发现普赖尔山脉的9种类型在其他地方没有报道，14种在全球罕见。这种稀有植被类型的集中，加上以前记录的稀有植物物种的出现，突出了普赖尔山脉重要的生物多样性价值。
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 Bureau of Land Management lands in the south Pryor Mountains, Carbon County, Montana. 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 types of 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.
