Mid-Atlantic Early Detection Network (MAEDN) is a vast network of land managers, field experts, citizen scientists, naturalists, gardeners and others interested in documenting invasive plant occurrences in the mid-Atlantic region for the purposes of early detection, improved management and better coordination. The region includes Delaware, Maryland, New Jersey, New York, Pennsylvania, Virginia, West Virginia and the District of Columbia.
The current focus is on invasive plants but additional invasive insects and diseases have been included in this App. Releases of approved biological control agents can also be reported using EDDMapS but not currently included in this App. Thanks to support from Invasive Plant Control, Inc., National Park Service and USDA Forest Service, EDDMapS, MAEDN and the MAEDN iPhone app is available to users at no cost.
