Birds since Bioindicators
Park executives know the importance of understanding ecosystem wellness inside the a vibrant environment particularly a barrier island. New NPS Directory and Keeping track of Program (having Assateague Island, the Northeast Coastal and you can Barrier Community) conducts long-name environmental monitoring to incorporate rewarding analysis so you can park managers and you will the general public.
