A long term ecological monitoring program is being conducted to monitor for possible electromagnetic effects that operation of the U.S. Navy's ELF Communications System might have to resident biota and their ecological relationships. Monitoring studies were selected through a peer reviewed, competitive bidding process in mid-1982, and work on most studies began in late summer of that year. Preliminary activities of the program consisted of site selection, characterization of critical study aspects, and validation of assumptions made in original proposals. Data collection for studies at the Naval Radio Transmitting Facility (NRTF)-Clam Lake, Wisconsin was completed, as scheduled, during 1990. Data collection for studies at the NRTF-Republic, Michigan is planned to continue through 1992. This report summarizes the progress of the monitoring program during 1990. To date, investigators conclude that on effects have occurred on biota exposed to EM Fields produced by either a fully operational or an intermittently energized ELF transmitting produced by either a fully operational or an intermittently energized ELF transmitting facility.

The professional literature published and available since August 1984 on the biological, ecological and health effects from exposure to Extremely Low Frequency (ELF) electromagnetic fields is compiled alphabetically by principal author. Each of the 485 citations is categorized according to electromagnetic field characteristics. Key biological and engineering terms are provided, and species of interest are identified. (Author)

The purpose of the Ecological Monitoring Program is to study ecological and/or biological characteristics of selected biota in an environment that includes natural stresses and low-level ELF electromagnetic fields. Sixteen general types of organisms from three major ecosystems in the System area are being examined. Study sites were selected in 1982, and will be examined further in 1983. Statistical methods of analysis proposed by investigators are identified, and biological and ecological end-points selected for study are described. Data collection began in 1982 and will be continued in 1983 for studies of vegetation, soil animals, pollinating insects, small mammals and birds, wetlands, vegetation associations, and aquatic community relationships., See also AD-A130 671.
