A narrow endemic known only from shale barren regions of Virginia and West Virginia; one of the most restricted shale barren endemics. Less than 60 occurrences are believed extant, most of these made up of fewer than 50 individuals; there are perhaps fewer than 4,000 plants altogether. Most occurrences are on public lands. predominantly National Forests. Because of the highly stressful nature of shale barrens environments, this species is not believed to be capable of tolerating much additional disturbance. Threats include road/trail construction and maintenance, erosion, inundation resulting from flood control measures, deer browsing, competition from exotic plants, and declines of its pollinators due to the spraying of Dimilin and BT insecticides for gypsy moth control.
Insecticide spraying for control of gypsy moths with Dimlin has a potentially devastating effect on the pollinators of A. serotina (USFWS 1991).
Habitat loss has occurred as a result of road construction, railroad construction, hiking trails, and dam
34 extant populations; most under 100 plants, and many contain fewer than 10 individuals (USFWS 1991)
An extensive research program is underway in Virginia to study the life history through six intensively studied populations. Contact: Garrie Ralph, 1943 Kings Road, Glen Allen, VA 23060.
The West Virginia Natural Heritage Program is currently conducting a five-year study on the demography of a population occurring on a federal property in West Virginia. Contact: P. J.

All Virginia populations occur on public land and are offered protection. The Virginia Department of Agriculture and Consumer Services (VDACS) is responsible for monitoring all Virginia populations.
Current research efforts should provide information necessary to formulate conservation needs.
