Tree disease leaving ‘zombie forest’ in its wake, expert warns

A forester from Bancroft, Ont., says the province could be doing much more to deal with an insidious disease that’s killing beech trees across Ontario.

Svetlana Zeran called in to CBC’s Ontario Today Monday to say beech bark disease is a major concern on the nearly 400,000 hectares of forest her company manages.

“We have been dealing with beech bark disease for about a decade,” Zeran said. “Now that it is here on the [Canadian] Shield, it is moving very rapidly and we are seeing the disease come in and infect the trees and they are dead within two to five years.”

The disease begins when an insect bores holes in the bark, allowing a red fungus to invade the tree and slowly weaken it from the inside out.
