In a report published by the University of Wisconsin-Madison in the proceedings of the National Academy of Sciences, it was revealed that climate changes are causing the mountain pine beetles to move towards higher altitudes of the mountain.
The change is posing a threat to Whitebark pine, which is found on the Rocky Mountains, coast range of B. C. and the northern US. A report earlier said that beetle epidemic killed about 710 million cubic meters of the pine timber which was of great commercial use.
A similar threat is now anticipated for Whitebark pine. The earlier outbreak affected about 53% of all the pine in the province. Since then, rate of damage got slowed down but it is again expected to rise to 58% by 2017.
