Do mobile communications base stations affect birds, animals or plants such as trees?

In April 2007 a spokesperson for the British Trust for Ornithology was quoted as saying: "I can't think of any reason mobile phone masts would affect them [birds]." In 1999, the WHO International EMF Project, the ICNIRP and the German Federal Office for radiation Protection (BfS) hosted a seminar on the effects of electromagnetic fields in the environment. The seminar examined whether there are effects on animals (flora and fauna) from environmental radio signals. In his presentation, the ICNIRP Chair concluded: '...adverse EMF effects in the environment are unlikely at exposure levels comparable to reference levels for general public exposure. Some species may need special considerations.
