Rank ReasonsEriogonum polypodum is a perennial forb that is endemic to subalpine and alpine conifer woodlands and sagebrush communities of the southern Sierra Nevada mountains of California in the western United States. There are between 21 and 80 estimated occurrences of this species, though little is known about threats and trends. Monitoring existing populations is important to improving our understanding of the status of Eriogonum polypodum.
Range Extent CommentsEriogonum polypodum is endemic to the southern Sierra Nevada mountains in Fresno and Tulare counties, California in the western United States (FNA 2005). The majority of populations occur to the west of Mt. Whitney. Range extent was estimated to be 9,080 square kilometers.
Occurrences CommentsThe number of occurrences was estimated to be between 21 and 80.
Threat Impact CommentsThreats to Eriogonum polypodum are likely low because many occurrences occur on protected lands in Sequoia and Kings Canyon National Parks, and in areas with low levels of anthropogenic impacts.
