EDMONTON- Albertans may have survived last week’s extreme cold, but experts are hoping mountain pine beetles did not.
Temperatures in Jasper, Hinton and Sundre — key battlegrounds in the fight against pine beetles — dipped below -40 a couple of times during the recent cold spell.
University of Alberta biological sciences professor Janice Cooke says early projections show it might have been enough to kill more than 95% of pine beetle larvae.
Caroline Whitehouse, a forest health specialist for Alberta’s Ministry of Forestry, says it typically takes a few years of large-scale cold events to cause notable mortality rates in pine beetles.
