Alberta claims progress in war on pine beetles

Alberta, one of two western Canadian provinces battling a more than decade-old infestation of mountain pine beetles, claimed progress in the fight on Tuesday but warned the war is not yet won.

The infestation in Alberta and British Columbia has cut into supplies of major forestry companies including West Fraser Timber Co (WFT.TO), Canfor Corp (CFP.TO), Tolko Industries and a host of independent sawmills.

Surveys indicate fewer trees were attacked in Alberta this summer than a year ago, and there were no migration of new beetles over the Rocky Mountains from British Columbia where the outbreak began in the mid-1990s, officials said.
