Abstract: This portion of the report includes monitoring of and data for arthropoda and earthworms; pollinating insects; and small mammals and nesting birds. During the 1990 growing season the ELF antenna was operated more frequently than in prior years. This provides 2 years of intermittent ELF exposure for the biological systems to react to the radiation, one year of very limited exposure and greater exposure in 1990. Arthropod and earthworm sampling was conducted at intervals of two weeks from early May to late October. High voltage transmission lines and magnetic fields have been shown to affect honeybee reproduction, survival, orientation, and nest structure. ELF EM fields could have similar effects on native megachild bees. Changes in cell length, number of cells per nest, number of leaver per cell, orientation of nest entrances, and time to collect a round leaf pierce to cap a cell were monitored. We have not detected significant changes that could be attributed to ELF EM fields. Small mammal and nesting bird biological studies in the western Upper Peninsula of Michigan for the year 1990 are reported.
