Crews conduct R-Value surveys at sites across the province to determine beetle overwinter
survival rates.
Mountain pine beetle infested trees are cut and burned to kill the beetles living
underneath the bark. Infested trees must be controlled before June 15 to ensure
the beetles do not emerge and fly on to infest other healthy pine trees.
If successfully attacked, tree foliage will change colour from green to yellow in
the first few months. This will be followed by bright red, brown and eventually
grey.
