Then, why are trees dying in Rocky Mountain National Park?

Trees have also been weakened by a prolonged period of low precipitation. The combination of milder temperatures and low precipitation has aided a vast outbreak of beetles.

Why is the mountain pine beetle a problem?

Is the mountain pine beetle an invasive species?

It is now considered an invasive pest, as it has spread beyond its native range. Mountain pine beetle is an insect, native to western North America, where its main host is lodgepole pine.
