2.C. Biological Features 2.C.2. Lichens An intensive lichen survey was conducted throughout Turnipseed in 2009-2010, cataloging over 150 species. Lichens were found in all habitats except for open water and fallow fields. In forested and rocky habitats lichens were found growing on many kinds of substrate, including rock, soil, wood and bark of many trees and shrubs. Corticolous (bark-inhabiting) lichens were found throughout the forest profile, from exposed roots on the forest floor up along stems and trunks in the understory and into the canopy as represented by fallen branches and twigs. Some lichens were even found growing over mosses and other lichens on these substrates. Distinct lichen communities could be discerned on the forest floor, understory and canopy layers, plus rocky habitats of shaded, partly-shaded and exposed outcrops, the latter including wetland overlooks along Gin Branch and flatrocks near Turnipseed Rd. The most distinct communities were on granitic flatrocks, which were dominated by several cladonia species. Several (55) new county records were discovered as well as some (13) state records and a few (7) seemingly undescribed species new to science. The lattermost need further study to determine their taxonomic status. Since lichens are known to be sensitive to air pollution, they can be used as indicators of environmental quality. As part of the lichen survey, an evaluation was made by tallying the number of known pollution-sensitive and pollution-tolerant species and their relative locations at Turnipseed. Overall, eight pollution-tolerant and seven pollution-sensitive species were found. Pollution-tolerant lichens, which were found dominating urban trees in Raleigh, were largely found in exposed areas of forest edges and the canopy as well as on partly-exposed rock. Pollution-sensitive lichens, which were absent from urban trees, were found growing in shaded forest interiors, some near water. Therefore, Turnipseed can be considered fairly healthy in terms of its air quality, compromised by the surrounding air pollution from nearby roads and human communities. A checklist is presented as an appendix; a more detailed report is being prepared for publication in the scientific literature. Appendix: Lichen Checklist Preliminary checklist of lichens and their ecology from Turnipseed Unit #1. Incompletely determined taxa may represent undescribed species and need further study. (S) = pollutionsensitive, (T) = pollution-tolerant. Taxa in red need verification / determination by outside experts.
