Confined to small areas on a few very high, rocky summits in the Blue Ridge Mountains in North Carolina and Tennessee. There are 5 populations currently known to exist in NC. 4 of those populations are protected. Another 3 historical populations were extirpated by extensive recreational and residential development. However, the largest population currently known is thriving despite heavy recreational use of the site.
Trampling and habitat disturbance from heavy recreational use of habitat
Acid precipitation and other forms of atmospheric pollution.
Three populations are known, and the largest of these is thriving despite heavy recreational use (NatureServe 2001). Approximately 2000 plants were known when the Recovery Plan was written (USFWS 1987).
Protection of existing populations and habitat.
Further study is needed in a number of areas, including:
Specific management requirements
Demographic studies of each population
Roles of biotic and abiotic environmental factors and disturbance on plant and population vigor
The potential effects of acid precipitation
Management needs include
Searches for additional populations
Implementation of management requirements when determined
Propagation techniques, further seed collection.
