Rank Reasons
Allium validum is common in California, scattered in northern Nevada, and occurs north to Washington. Previously thought to occur in southern British Columbia, but voucher evidence for these reports has not been found. It is also known from western Idaho. Livestock grazing, mining, and timber harvesting all pose threats to this taxon.
Range Extent Comments
Throughout the Great Basin on the east side of the Cascades, from Washington to California, east to Nevada and western Idaho. Vouchers for literature reports in British Columbia could not be found (BC CDC data 2007).
Threat Impact Comments
USFS: Livestock grazing, mining, and timber harvesting are the most significant threats.
