Wild birds once the Bioindicators
Park professionals recognize the importance of training ecosystem wellness in the a beneficial active environment for example a boundary area. The new NPS Catalog and you can Keeping track of Program (to own Assateague Area, the brand new Northeast Coastal and you will Barrier Network) conducts much time-name ecological keeping track of to add rewarding data so you’re able to playground managers and you can people. That vital indication that is recognized try tree wellness, which has tree design, structure and creatures fictional character (NPS 2024). The team out-of scientists was basically surveying depending enough time-label monitoring plots about .
