Common name(s): English: Appalachian Dust Bunnies

ASSESSMENT JUSTIFICATION [criteria: A2ce]

Lepraria lanata is a southern Appalachian endemic species with very few remaining extant subpopulations. Widespread logging in the 20th century, along with introduction of the Baslam Woolly Adelgid (Adelges piceae), has led to substantial reductions in the amount and quality of available habitat for this species. Therefore, it is listed as Endangered, A2ce. Climatic changes, including a rising cloud layer and hotter drier temperature pose serious threats to this species in the coming century, and so thepopulation should be monitored carefully.
