Professor Staffan Lindgren of the UNBC Forestry Department says the cold snap we are having is too little too late to do any damage to the Mountain Pine Beetle infestation.
Professor Lindgren says "Had we had this weather say two or three weeks ago it might have had some effect. The beetles are now pretty well protected and it would take temperatures of -30 to -35 for an extended period of time, about two weeks to have any effect."
While -20 may seem pretty cold to us, but Lindgren says but it isn’t enough to kill off the beetles "They have become accustomed to this type of weather over the past week.
It may kill off the odd one but believe me,the weather hasn’t done any major damage to the beetles."

So, did we all forget what winters used to be like which kept the MPB in check? Maybe we are starting to take on lower mainland characteristics by complaining about "normal" weather, believing it is abnormal, when actually it isn't?
Then again, maybe the beetle kill off theory as it is presented to us is a bit oversimplified.
