Rank Reasons
Endemic to southeastern Arizona in the Pinaleno Mountains and other nearby Sky Island mountains. Locally abundant. Threats that may affect the species include recreational activities, forest management, fire, and grazing.
Range Extent Comments
Known primarily from the Pinaleno Mountains in Graham County, Arizona, and from a few outlying collections in other Sky Island mountains of southeastern Arizona: Huachuca Mountains in Cochise County, Rincon Mountains and Santa Catalina Mountains in Pima County, and Mogollon Rim in Greenlee County (Kearney et al. 1951; SEINet 2018; Ertter 2007; Flora of North America Editorial Committee 2014).
Occurrences Comments
There are approximately 6-7 extant occurrences in Arizona based on collection data (pers. comm. C. Flowers 2019).
Threat Impact Comments
Low threats from recreational use, forest thinning, and fire are mentioned within the Coronado National Forest, Graham County, Arizona (USFS 2008). Potentilla albiflora habitat is within an area where grazing is allowed (NatureServe Network Database as of October 2018).
