Cold weather helped to kill pine beetle in Alberta

New scientific data suggests frigid temperatures this winter have killed off, more than 90 per cent of the mountain pine beetles, in Alberta forests.

However, experts won’t know until later this spring, if the death rate is high enough to actually stop the destructive bugs, from continuing to spread east, to new healthy trees.


Computer models run by the Canadian Forest Service indicate, that 95 per cent of the beetles have died in southern Alberta and the Rocky Mountain Parks, after devouring vast areas of forest, in the BC interior.

However, experts say, the kill rate must reach a staggering 97.5 per cent to keep the bugs in check.
