Trees have also been weakened by a prolonged period of low precipitation. But the scope and intensity in the past two decades is anything but normal, scientists say, in large part because rising temperatures are preventing the widespread winter die-off of beetle larvae, while also enhancing the beetles’ killing power.

Hard winters with cold temperatures can kill beetle eggs and larvae wintering under a tree's outer bark. Bark beetle populations and their subsequent damage varies greatly between years and by location within any given year. High value trees are in front country locations such as campgrounds, historic landscapes, picnic areas, park buildings and infrastructure, and visitor centers. The beetles are now advancing up the Atlantic coast, reaching New York’s Long Island in 2014 and Connecticut the following year.

Mountain pine beetles can damage whole regions of forest. Pines can overcome bark beetle attack by producing pitch, but pitch cannot be produced in sufficient quantities when stressed under drought. Take the southern pine beetle, which until recently was restricted to its native habitat in Central America and the southeastern U.S., because its larvae die when cold winter nights drop bark temperatures below 14 degrees F. The latitude of that lethal chilling limit has been creeping northward by about 40 miles a decade since 1980, the new study by Columbia University researchers finds.
