Description:

Solidago albopilosa is a herbaceous perennial tetrapoloid goldenrod, 1-2 ft in height, producing bright yellow, fragrant flowers from September to November and setting seed from October through December. It was discovered by Dr. E. Lucy Braun in 1940 and officially described by her two years later (Braun, 1942). S. albopilosa resembles S. flexicaulis, but is distinguished by its habitat, white hairs on the stems and leaves, decumbent habit, and leaves "so thin that coarse print is readable through [them]" (Braun, 1942). All occurrences are found within three counties in the Daniel Boone National Forest, in the Red River Gorge area, with a few on private inholdings. The plants grow in sandstone rockhouses, many of which were used historically as shelters by Native Americans. This very limited habitat is threatened particularly by recreational activities, including hiking, rock climbing, camping, and illegal digging for Native American artifacts, which result in physical disturbance and soil compaction. Although some of the original occurrences have been extirpated, some new occurrences have been found in recent years. Protective measures have been taken for those most vulnerable to damage by recreational activities. Searches for the plant in suitable habitat in neighboring counties have not been successful, although not all possible sites have been found.

Where is White-haired Goldenrod (Solidago albopilosa) located in the wild?

Habitat:

S. albopilosa grows between 800 and 1300 ft elevation in the mixed mesophytic region of the Eastern Deciduous Forest. It is found only in sandstone rockhouses, in sandy soil and on ledges, with a soil pH of 4.5-5.0. It grows behind the drip-line of the overhanging sandstone in a partially shaded environment and does not occur in the darkest portions of the rockhouses and only rarely in open sunlight.

Distribution:

S. albopilosa is found only in the Red River Gorge area of the Daniel Boone National Forest in Menifee, Powell and Wolfe Counties in Kentucky.

States & Provinces:

White-haired Goldenrod can be found in Kentucky

  • Genetic Research

Early work on S. albopilosa determined that it was a tetraploid (n=36) (Beaudry, 1959), in contrast to S. flexicaulis (n=18), a wider-ranging woodland species that occurs in the same forests as S. albopilosa. More recent work has shown that forms of S. flexicaulis in the western part of its range, including Kentucky, are also tetraploid (Semple et al., 1984; 1993). Genetic work has investigated the possibility that S. albopilosa arose as a hybrid between S. flexicaulis and S. caesia, a species known to hybridize with S. flexicaulis. Results indicate that it is unlikely that S. albopilosa is of hybrid origin from these species and that it is not closely related to either species. However, it is most similar to S. flexicaulis, and may have arisen from it as an ancient autopolyploid (Esselman and Crawford, 1997).

  • Climate Research

In 2017, Matthew Albrecht and Quinn Long initiated an experiment using incubation chambers to simulate the germination response of S. albopilosa to projected future temperatures in the year 2080 and compare trends in cumulative germination as well as the timing of germination events to temperatures that are consistent with current climate averages.

  • Seed Collection

In 2016 and 2017, Matthew Albrecht and Quinn Long collected seeds from 36 populations throughout the Red River Gorge, resulting in the acquisition of an estimated 239,780 seeds having been collected from approximately 930 individuals.

Endemic to a single river gorge in Kentucky and restricted within this narrow range to sheltered, cave-like ""rockhouse"" habitats which tend to receive intensive recreational use. Many populations have been severely damaged or extirpated by trampling. Major threats are trampling and digging by archaeologial looters.

Simple, low fencing has been used to delineate the areas where S. albopilosa is growing in areas that receive higher traffic, and the fencing is generally respected by the public. Some trails have been rerouted to move them away from areas with S. albopilosa, and signage has been used to alert those using the forest of the need to conserve the S. albopilosa habitat (D. Taylor, pers. comm.). Forest Service policies on logging are used to protect S. albopilosa from the direct effects of logging and to protect sensitive cliff-line plants (USFWS, 1993).

A study of the effects of ozone on S. albopilosa indicated little effect at the concentrations tested (Mavity and Berrang, 1994). An assessment was made of the impact of recreation on S. albopilosa and found that 85% of the sites assessed were impacted and in one-third of these, the impact was severe (White and Drozda, 2006)
