Abstract : The U.S. Navy has completed a program monitoring flora, fauna, and ecological relationships tor possible effects from electromagnetic fields produced by its Extremely Low Frequency (ELF) Communications System. This report documents studies of small mammals and nesting birds conducted near its transmitting antenna in Michigan. From 1982 through 1993 researchers from the Michigan State University (MSU) monitored organismal and population aspects of vertebrates in areas near (treatment) and far (control) from the Michigan antenna. They examined the reproductive, developmental, behavioral, and physiological characteristics of representative vertebrate species. Studied species were the deer mouse, chipmunk, tree swallow, and blackcapped - chickadee. Investigators had also monitored ecological aspects of the mammalian community until 1988 when this study element was discontinued due to highly variable results. In a different prolect, ornithologists from the University of Minnesota-Duluth monitored the ecological characteristics of the bird community near the ELF System. The MSU research team used several statistical tests to examine data; however, nested analysis of variance was the most often used test. Based on the results of their study, they conclude that the EM fields nroduced bv the Naval Radio Transmitting Facility-Republic, Michigan did not affect small vertebrates.
