Forest Health Monitoring 1994 Field Methods Guide - Lichen Communities, amended

Call Number:

Abstract:

The purpose o.f the lichen community indicator is to use lichen species and communities as biomonitors of change in air quality, climate change, and/or change in the structure of the forest community. Lichen communities are excellent indicators of air quality, particularly long-term averages of sulfur dioxide concentrations ( Hawksworth and Rose, 197 6; Smith et al. , 1993; van Dobben, 1993). <br> Lichen communities provide information relevant to several key assessment questions, including those concerning the contamination of natural resources, biodiversity, and sustainability of timber production. Lichens not only indicate the health of our forests,. but there is a clearly established linkage to environmental stressors, as described. <br> The objectives of this task are to determine the presence and abundance of macrolichen species on woody plants in each plot (using the 120-foot radius core of the plot) and to collect samples to be mailed to lichen experts. <br> Includes Data Sheets.
