Wild birds as Bioindicators
Park managers admit the necessity of studying ecosystem wellness for the a beneficial vibrant ecosystem instance a boundary isle. The newest NPS List and you will Overseeing System (to possess Assateague Isle, the fresh new Northeast Coastal and you can Burden System) conducts a lot of time-name environment keeping track of to add valuable data so you can park professionals and you can the general public.
