I remember reading an article about this in New Scientist. After several years of operation they had found the Trees to either side of the antenna were growing taller and stronger than the rest of those in the Forest.

The antenna was to be used to communicate to submarines deep under water using something like 30 Hz or 60 Hz radio waves. The antenna was a long (miles long) cable buried underground. There were many battles between the local citizens, various environmental and animal groups, and the government (US Navy?). If I recall correctly, there were even court cases trying to prevent the antenna from being installed. The concerns were related to what effect the RF would have on the environment to include plants and animals. Don't know for sure, but I believe the antenna was actually installed and was/is operating. Might be worth a look to see what came of that and to see what arguments were made pro/con. Might even be something came out of all that related to what you want to know.

However some people have asked us if there is any standard/recommendations limiting the exposure of forests, lakes/rivers, animals, etc to RF fields. Do you know any FDA and EPA (or another agency) that regulate this subject of RF fields incidence? Example: Imagine a radio-base station (mobile comm) or antenna (TV or radio) put in the middle of a forest, where there is not human habitation, but we have animals, trees and waters. Is there any standard/recommendation related to this case (only for non-ionizing radiation, ie, EM radiation). Thanks in advance and Regards, Muriel
