Gypsy Moth in Monongahela National Forest, WV

ForWarn found a decline in greenness in the Monongahela National Forest of West Virginia in August, 2015. Gypsy moth is a historical defoliator of these areas, their damage covering one million acres in 2015. The large decline in vegetation by the gypsy moth may indicate the start of a population outbreak for the species.
