Environmental Studies


A lichen is a unique organism consisting of a mutualistic symbiotic relationship between an algal and fungal species. These two distinct components physiologically and anatomically function as a single organism. Due to their high sensitivity to environmental stress and air pollution, these sessile organisms are important indicator species that can be monitored to evaluate the impacts of climate change. The aim of this study is to replicate a lichen survey completed at Bates Morse Mountain Conservation Area in 1983 to compare changes in lichen abundance and distribution. Quantitative surveys were completed to calculate constancy and frequency values of corticolous, saxicolous and lignicolous lichen species in four distinct natural communities at Bates Morse Mountain Conservation Area.
