Mountain Pine Beetle tree mortality linked to resin duct size


Minister of Fire
A few years ago I heard talk locally of a study by the University of Alberta relating to the lower than expected mortality in some areas of our pine forests from the mountain pine beetle. Especially considering our forests aren't adapted to the MPB as they are north and east of the traditional range of the MPB. The study was published over a year ago but I finally found it tonight. According to the study trees with larger resin ducts have a higher survival rate. Last I heard foresters were looking at some of our specific pine species for MPB resistance in their reforesting operations, where this has went though I'm not sure.

Well that right there is evolution. Beak of the Finch in your very back yard.
