Rank Reasons
Pedicularis centranthera is a wide-ranging perennial herb in evergreen forests in the southwestern United States from Colorado and New Mexico west to Oregon and California. Little is known about threats or trends, but with a large range extent and large number of occurrences, this species is considered secure.
Range Extent Comments
Pedicularis centranthera occurs in the southwestern United States from Colorado and New Mexico west to Oregon and California (FNA 2019). Range extent was estimated to be over 960,000 square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Occurrences Comments
By applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1993 and 2024, it is estimated that there are over 550 occurrences rangewide (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Threat Impact Comments
Although threats are not widely documented, this species is potentially threatened by grazing, invasive species, and other threats in some places.
