Alberta makes progress fighting eastward march of tree-killing pine beetle

New aerial photos suggest Alberta is making progress halting the eastward march of the voracious, tree-killing mountain pine beetle.

The surveys show about 50 per cent fewer red beetle-killed pine trees where control programs are in effect, primarily in west-central Alberta and east to Slave Lake.

"This year's surveys show some positive results where the province's mountain pine beetle control strategy has been most aggressive," said Sustainable Resource Development Minister Frank Oberle in a news release.
