Wild birds due to the fact Bioindicators
Park professionals admit the significance of understanding ecosystem fitness in a active environment such as for example a barrier area. The fresh NPS List and you may Monitoring System (to own Assateague Island, the newest Northeast Seaside and Barrier Community) conducts a lot of time-term ecological overseeing to provide worthwhile study to park managers and you can people. One crucial indication that’s been recognized is actually forest fitness, with forest framework, structure and creatures character (NPS 2024). Their group out of experts had been surveying mainly based a lot of time-title overseeing plots on the .
