Wild birds due to the fact Bioindicators

Park executives acknowledge the significance of training environment fitness for the a good vibrant environment such a boundary area. The new NPS Inventory and Overseeing Program (getting Assateague Island, the brand new Northeast Seaside and Barrier Network) conducts enough time-label ecological overseeing to include valuable studies to playground managers and people. That essential sign that has been recognized try forest health, that has forest construction, composition and you can animals figure (NPS 2024).
