Abstract

In the final report on the lichens and air quality in the White Mt. National Forest Wilderness areas (Wetmore, 1989) it was recommended that a restudy of the elemental analysis of lichens be done every five years. This report is on the first restudy done in 1993. In this study five species of lichens were collected during August, 1993 at the same localities as in the previous study. The methods used were the same as in the previous study. The results of this study showed similar or slightly lower levels of most elements in most species. ANOVA and pairwise comparisons by statistical analysis showed significantly lower levels in 1993 than 1988. No one locality had consistently higher levels of accumulation. The elemental levels in the White Mt. wilderness areas were lower than in the Lye Brook Wilderness of the Green Mt. National Forest. It is concluded that there probably has been no degradation in the air quality in the wilderness and there might have been a slight improvement in the air quality. The recommendation is made that the periodic five-year restudy of elemental analysis be continued.
