Here are examples of honest concern over EM fields from telecoms affecting wildlife:
• The Kompetenz initiative writes urgently to bee associations and beekeepers and explains about EM fields and bee colony collapse

Electromagnetic fields and trees
There are some very interesting pieces of research and anecdotal evidence related to possible physiological effects of EMFs.
Research indicates that microwave radiation may be partially responsible for some cases of partial deforestation:

• Volkrodt W: ‘Droht den Mikrowellen ein ahnliches Fiasko wie der Atomenergie?’ (Are microwaves threatened by a fiasco similar to that of nuclear energy?)
Dr Hertel’s work also includes photographs and maps of an apparently effected areas, with the photos showing what is alleged to be damage to tree growth caused by microwaves – with markedly different ring profiles noted on different sides of the cross-sections taken through the trunks. Lines of deforestation followed line of transmission. Though there are other possible explanations for some noted occurrences such as the light and shade the trees have been exposed to in the past and geoelectromagnetic anomalies affecting growth patterns and die-back, the research seems highly competent and worthy of further investigation.

• Damage to trees – ‘Oak Die Back’. In the book Electromagnetic Environments and Health in Buildings (2004) edited by Derek Clements-Croome (p. 263), Anne Silk noted in that in work she did for the Forestry Commission on very rare conditions of oak trees, ‘Oak Die Back’, where ‘the tree dies from the top down, instead of from the roots upwards as is usual. … [She] was given over 100 sites in the UK and was able to pinpoint the common distance between sick trees and high multi-mast user. This would appear to indicate that such (modulated) fields interfere with plant hydraulics and the electroosmotic processes taking place within the trees themselves by masking natural electrical fields, particularly those experienced under ‘fair weather’ conditions. Alternating or inverted fields have already been shown to have biological effects on humans and animals – see Jamieson KS, Bell NB, ‘Distorted current flow – the forgotten factor in EMF research?

The Skrunda Radio Location Station (RLS), which has operated continuously for more than 20 years, has created a unique area for the study of pulse radio-frequency electromagnetic field effects. Trees were chosen to assess these effects. Since 1990, permanent plots have been established in pine forest stands around the Skrunda RLS and in control areas. The dynamics of tree growth changes were analysed using retrospective tree ring data. There is a statistically significant (P < 0.01) negative correlation between the relative additional increment in tree growth and the intensity of the electric field. The radial growth of pine trees has diminished in all plots that received electromagnetic radiation. This decrease in growth began after 1970, which coincided with the start of operation of the Skrunda RLS, and was subsequently observed throughout the period of study. The effects of many other environmental and anthropogenic factors were evaluated, but no significant effects on tree growth were observed.
Leylandii are notable for their ability to screen EM fields, but a long time ago the antenna properties of trees were known:
• Tree antennas, Scientific American, July 14, 1919, p. 624
It was estimated in 2009 that the carbon dioxide emissions produced globally by the telecoms industry released 110.7 million tonnes of Co2 into the atmosphere. That is equivalent to emissions from 29 million cars. ( Bennett 2009 ).
