From overhead, the forests just south of this city are a lush green blanket stretching west to the Rockies.
Poplars are beginning to show signs of fall as leaves turn to yellow. But for forestry workers, the only colour they are focused on is red. To them, the swaths of pine trees turned red is the sign of one thing: mountain pine beetle.
The pine beetle is a small, dark beetle that burrows beneath the bark of pine trees. The pests the tree with larvae and a blue fungus that it excretes when it feeds.
