While he might have been caught in the another websites each year, per get have took place the latest southwestern place of one’s forest.
Wild birds given that Bioindicators
Park professionals recognize the necessity of reading ecosystem health into the a active ecosystem such a buffer area. This new NPS Directory and Overseeing Program (to have Assateague Island, the Northeast Seaside and you can Barrier Network) conducts much time-label ecological overseeing to add worthwhile research so you can playground executives and you may anyone. You to important signal that’s been understood is actually tree health, with forest design, structure and creatures figure (NPS 2024). Their people of experts was basically surveying situated much time-title monitoring plots on the . Once the bird assortment and you will society dynamics is bioindicators from forest wellness (Drever & ), park managers added the new Maps system to compliment their experience with new maritime forest ecosystem.
