Common name(s): English: Gladys' Mountain Spikes

ASSESSMENT JUSTIFICATION [criteria: B1ab(iii)+2ab(iii)]

Lepra andersoniae has a limited Extent of Occurrence (4,027 km²) and Area of Occupancy (16 km²), alimited number of locations (3), and there are ongoing declines in habitat quality inferred from thelarge-scale changes to southern Appalachian spruce-fir ecosystems as a result of changing climate and environmental conditions. The species occurs in highly visited areas and may be threatened by recreation either directly through trampling/damage to rock habitats, or indirectly through expansion or improvement of recreation infrastructure. Therefore, it is listed as Endangered under criteriaB1ab(iii)+2ab(iii).
