Wild birds given that Bioindicators

Park professionals admit the importance of studying ecosystem health in a beneficial active ecosystem like a shield island. New NPS Collection and you can Monitoring System (having Assateague Area, this new Northeast Coastal and you can Hindrance Network) performs a lot of time-label ecological monitoring to provide valuable research to park executives and you will individuals.
