In an effort to stem the decline of teh population and help move the Grat Bay towards cleaner water and a more robust ecosystem multipule organizations are working together on this restoration project. The Nature Conservancy and The University of New Hampshire, together with other partners, are teaming up to rebuld degraded oyster reef habitat in the Piscataqua Region Estuary of New Hampshire and Maine. Thanks to support from dedicated members like you, the program has successfully restored more than eighteen acres of reef and 3.5M oysters to the system since 2009. Oysters are an ecological linchpin of the estuary, providing essential fish habitat and water quality regulation services. In recent years the team has scaled-up efforts, with as much as five acres and 1 million oysters restored annually.
