Floristic Provinces of Sagebrush and Associated Shrub-steppe Habitats in Western North America

Boundary for floristic regions used for the conservation assessment of Greater Sage-grouse and sagebrush habitat conducted by the Western Association of Fish and Wildlife Agencies. The floristic provinces were digitized from a figure from Miller, R. F., and L. Eddleman. 2001. Spatial and temporal changes of sage-grouse habitat in the sagebrush biome. Oregon State University, Agricultural Experiment Station. Technical Bulletin 151.

本数据集包含美国鱼类与野生动物机构西部协会（Western Association of Fish and Wildlife Agencies）开展大艾草松鸡（Greater Sage-grouse）及其艾灌丛（sagebrush）栖息地保护评估时所用的植物区（floristic region）边界数据。
该植物区系省（floristic province）数据源自Miller, R. F.与L. Eddleman于2001年发表的文献图表，原文题为《艾灌丛生物群系中艾草松鸡栖息地的时空变化》，刊载于俄勒冈州立大学农业试验站技术公报第151号。
