The productive woodlands, estuaries, and coastlines of the Middle Atlantic region of North America have been home to Native Americans from the Paleoindian period to the modern day. Inhabitants of this region adapted to broad environmental changes, including the emergence of Chesapeake Bay when rising seas drowned the Susquehanna River valley around 8000 years ago. Estuarine conditions expanded throughout the Holocene, alongside the establishment of a rich and diverse forest environment. Much of the evidence for human harvesting of coastal resources has likely been obscured by sea level rise and modern development, but first appears around 5000 years BP. By the Middle Woodland (2500 to 1100 BP), people were harvesting oysters, clams, fish, and other bay resources as part of a broad foraging subsistence. When Europeans arrived, at least some of the people living around Chesapeake Bay were practicing agriculture while also harvesting oysters and other resources. Oyster harvesting was remarkably consistent and sustainable through time, with minimal impact on oyster populations or other environmental conditions. This long history of sustainable fishing practices in the face of persistent sea level rise and climate change suggests that reduced harvest pressure may be a key component to restoring modern Chesapeake ecosystems.
