ELF (Extremely Low Frequency) Communications Systems Ecological Monitoring Program: Wetland Studies

Abstract

This report documents the results and conclusions of in situ studies designed to monitor for possible effects on wetland flora from exposure to electromagnetic (EM) fields produced by the U.S. Navy's Extremely Low Frequency (ELF) Communications System. The studies examined for possible effects to herbs, shrubs, and trees growing on peat bogs near the Navy's Wisconsin Transmitting Facility (WTF). Plant characteristics studied included foliar cation content, stomatal resistance, and rate of foliar decomposition. Eleven bogs similar in plant community structure and interstitial water chemistry were used as study sites. Treatment sites were located immediately adjacent to the WTF antenna or its grounds, and experienced EM field intensities at least two orders of magnitude greater than control sites. Keywords: Extremely low frequency, Electromagnetic fields, Environmental studies, Ecology, ELF Communications system, ELF Ecological monitoring program.
