ELECTROMAGNETIC EFFECTS. “The effects of electromagnetic radiation on plants and animal life include the diminished radial growth of pine trees, lowered density of bird species and mammals, such as storks, sparrows and bats, effects on bees, effects on magnetic-based homing mechanisms of birds, and many other effects. Plants and animals can be monitored as environmental indicators to assess the effects of electromagnetic radiation.”
