Rank Reasons
Perityle gilensis comprised of two varieties, var. gilensis and var. salensis, has been reported from south-central Arizona, occurring in crevices in cliffs and in rocky canyons. This species is threatened by changes to the fire regime, both fire suppression and increased wildfire, potential hydrological changes, canopy closure (var. gilensis), and mining activities.
Threat Impact Comments
Threats to this species comprise the threats to its two varieties, var. gilensis and var. salensis, and include impacts from climate change, increased uncharacteristic fire low desert systems, tree canopy closure due to lack of natural fire, mining and changes in water use (USFS 2019).
