Maritime forest on barrier islands promote an alternative habitat having animals however they are against of several dangers associated with water-top increase and you can decimating bugs.
24 hours in the Banding Station
A great Charts bird bander’s date starts a couple of hours ahead of start. Since sunrays is on the rise through the loblolly pines, i open 10 mist nets pass on equally throughout the all of our 20-acre forest. 40 minutes later on, it’s about time on earliest web work with.

When we verify that we have compiled all of the appropriate study, i discharge the new bird unharmed. Immediately following half a dozen period of web works and you may banding, i close the fresh new nets and pack up brand new banding route. I will be right back for another banding tutorial in approximately 10 days.
Results after three years out-of Banding

Birds as Bioindicators
Park executives recognize the significance of learning environment fitness into the a good vibrant environment instance a barrier isle. The latest NPS Index and you will Overseeing Program (to possess Assateague Isle, the brand new Northeast Seaside and Hindrance Community) conducts much time-label environmental overseeing to include valuable data to park professionals and you will the public.
