Summary: The invasive species hemlock woolly adelgid is a threat to eastern hemlocks, filling some southeastern U.S. forests with what are called “gray ghosts” of the trees. Until recently, the insect had stayed in the southern part New York, but late last summer, an infestation was discovered in the Adirondacks. On this episode of Eyes on Earth, a New York university researcher talks about his effort to help detect the insect, which is the size of a poppy seed, by using remote sensing such as Landsat.
