They may be down but they’re not out: Damaging insects can emerge from fallen trees and logs for several years after a major storm, according to a U.S. Forest Service study that reinforces long-standing warnings against moving firewood from place to place.
Timber that gets blown down, broken or damaged by wind is often cut and used as firewood, which in turn can enable the spread of invasive, destructive insects that drain the life out of forests from New England to the West Coast.
Such pests are projected to put 63 percent of the country’s forest at risk through 2027 and carry a cost of several billion dollars annually in dead tree removal, declining property values and timber industry losses, according to the peer-reviewed study last year in Ecological Applications.
Researchers were surprised to find that wood harvested even three years after the tornado produced a significant number of insects.
