Yellowstone Np Report
Abstract
This project has three major objectives. The first is to collect and identify lichens from all representative substrates and vegetation types encountered in the study area, the Mammoth Hot Springs vicinity. The second is to establish permanent study plots on suitable substrates for subsequent sampling, using data from 1982-1983 as baseline information. The third objective is to specify lichen species present in this area of the Park that are sensitive to air pollutants.
