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. Navys Extremely Low Frequency ELF Communications System. The studies examined for possible effects to herbs, shrubs, and trees growing on peat bogs near the Navys 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.
