Invasive species from other parts of the world have become a serious problem as world travel and trade increases. We may think this is a new problem, but it has occurred throughout history as humans have traveled from place to place. Over a hundred years ago a fungus was introduced into this country that destroyed one of our most important forest trees, the American chestnut. This devastating disease not only eliminated a major forest tree throughout much of the Eastern United States, but eliminated a food crop for wildlife and an important timber producing tree. Today we still face the same challenges with Gypsy Moth, Emerald Ash Borer, Purple loosestrife and many other invaders. The following web pages will provide you with current information on the management of some of the more serious invasive species.
