UM study suggests slow-growing ponderosa better able to survive pine beetle 

Slow-growing ponderosa pines may have a better chance of surviving mountain pine beetle outbreaks in western Montana as climate change increases the frequency of drought and insects, according to new research from the University of Montana.

Led by UM biological sciences Professor Anna Sala, the team of researchers published its findings this month in the journal Proceedings of the National Academy of Sciences.

The study found that young families of fast-growing ponderosa pines typically survived to maturity better than slow-growing ones. But that wasn’t the case when mature trees were affected by a mountain pine beetle outbreak.
