White-haired goldenrod

The primary threat to the survival of white-haired goldenrod is the many visitors to rockshelters in the Red River Gorge area each year. In 1989, approximately 260,000 people visited the Red River Gorge Geological Area (Fig, personal communication, 1990). The Red River Gorge has an extensive trail system, and many of these trails pass through or near rockshelters. Damage by visitors reached a peak in the 1970's (Fig, personal communication, 1990). During this period, 75 percent of the occurrences of this species were severely damaged, and 11 occurrences (3,422 individuals) were extirpated (Varner, personal communication, 1990). One monitored occurrence declined from 415 stems to 85 stems, and another occurrence declined from 828 stems to 32 stems between the early 1970's and the mid-1980's (Varner, personal communication, 1990).
