Alberta faces new mountain pine beetle invasion from B.C. and mountain parks

Alberta is facing a new and bigger invasion of tree-killing mountain pine beetles and is looking to the federal government for help in preventing the tiny insects from spreading further east into the boreal forest.

Crews report a new wave of the bugs flew into the province in July from British Columbia and the mountain national parks in Alberta.

The hardest hit areas are in northwest Alberta - the same region where a high percentage of the tiny beetles died off last winter from extreme cold.
