Alberta scientists say pine beetles killing tree species found across Canada

Alberta researchers say the destructive mountain pine beetle has infested a different type of tree that could allow the pest to spread eastward across Canada.

University of Alberta scientists say they have proven the tiny beetles can jump species from the lodgepole pines of Western Canada to Jack pines, the main trees in the boreal forest.

The beetles have been found in Jack pines north of Edmonton and the bugs are knocking on Saskatchewan's door.
