As if our magnificent trees didn’t have enough problems, they’re now being threatened by our emails.
When they’re not being assailed by some foreign bug or moth, there’s often a council official looking for an excuse to cut them down.
Now researchers say radiation from Wi-Fi networks that enable our burgeoning online communications may be their latest enemy.
Research in Holland showed that trees that were planted in close proximity to a wireless router suffered from damaged bark and dying leaves.
The alarming study will raise fears that Wi-Fi radiation may also be having an effect on the human body and will lend weight to parents and teachers who have campaigned to stop wireless routers being installed in schools.
The city of Alphen aan den Rijn, in the West of the country, ordered the study five years ago after officials found unexplained abnormalities on trees which they did not believe had been caused by any known viral infection.
The researchers took 20 ash trees and exposed them to various kinds of radiation for three months.
The trees were exposed to six sources of radiation with frequencies ranging from 2412 to 2472 MHz and a power of 100 mW at a distance of just 20 inches.
Trees placed closest to the Wi-Fi radio developed a ‘lead-like shine’ on their leaves that was caused by the dying of the upper and lower epidermis.
This would eventually result in the death of parts of the leaves, the study found.
