    Whether you are hunting down the recently spotted Snowy Owl or checking off species on your life list, you could be protecting those very trees the birds of Vermont rely on. The Emerald Ash Borer (EAB) is an invasive forest pest that devours all three species of Vermont ash trees but you can help find early infestations of EAB by reporting woodpecker damage observed on ash trees.
