Abstract

Lichens in south Florida are poorly documented. I surveyed macrolichens on the bark of Southern live oak trees (Quercus virginiana) present on the John D. MacArthur campus of Florida Atlantic University in Jupiter, Florida, to establish a baseline and to determine how automobile pollution may impact lichen species diversity and density. Ten randomly-selected trees in each of two study areas (adjacent to Parkside Drive versus mid-campus, away from any road) were surveyed for lichen species diversity and coverage. Fifteen species of lichens were identified using identification keys and chemical spot tests. Lichen diversity was similar in the two areas of study, but overall lichen coverage was significantly lower in the area adjacent to Parkside Drive, likely due in part to greater exposure to air pollutants from automobile exhaust.
