Herring River 101: The Effects of Tidal Restriction and Restoration
Meet at the National Seashore parking lot on Griffin Island
First we will walk down the trail to the natural salt marsh near the Town Landing. Here we will discuss how the hydrology, chemical cycling, and plant and animal communities of salt marshes depend on their intimate connection with high-salinity coastal waters.
Next we will go over the 300-year history of alterations to New England's salt marshes, using Herring River as a typical, though exceptionally large, example.
Finally we will walk onto the Chequessett Neck dike, which has blocked tides from the estuary's 1100-acre flood plain since 1909, to discuss the damaging physical, chemical and biological effects of disconnecting the river from the marine environment.
These events are free and open to the public. Please RSVP to email@example.com
