Living Without Mountain Pine Beetle

Mountain Pine Beetle has killed millions of pines in the western US and Canada. The outbreaks are associated with warmer weather. Some efforts are being made toutilize the dead trees as lumber. Minnesota is worried about the spread of the beetle into its forests. Mountain Pine Beetles have been detected in wood shipped to Minnesota for firewood, lumber or furniture. Minnesota is proposing a quarantine that would ban the import of freshly cut logs from states where Mountain Pine Beetle is present.


The spread of wood boring beetles is affecting the quality of our forests. Entomologists have demonstrated that the pines common in Minnesota are suitable hosts for MPB. Protecting our forests in the era of invasive insects and changing climate requires restriction on movement of lumber and tree products that can spread undesired insects.
