Pine beetle proves resilient to winter wallop

The mountain pine beetle proved once again to be a tough foe, surviving a particularly nasty northern Alberta winter in greater numbers than anticipated.

The cold killed many of the voracious forest-destroying pests in the north, especially in the leading edge of the infestation near Whitecourt and Slave Lake.

But it was far from the knockout blow that forest-watchers were hoping for, government beetle fighters and researchers said Thursday.
