Our coastal preserves boast saltwater features like tidal marshes, rock and sand shorelines along with productive inter-tidal zones.  These preserves offer stunning views and glorious sunsets, and are among the most biologically productive areas in the country. They are also among the most threatened.

Salt marshes are formed and sustained by tidal activity and play an important part in the overall health of Long Island Sound.  Tides deposit sediment across low-lying coastal areas and form mudflats. Grasses and plant matter decay, while sediment builds, and hundreds of diverse organisms find home in the nutrient rich layers.  These layers become breeding grounds for fish and shellfish that populate the Sound.

When the GLT was formed, The Nature Conservancy deeded the Willowmere Salt Marshes land to us because of our local stewardship resources and proximity to the property. At high tide, water rises and floods the marsh grasses. At low tide, one can see the holes and tracks of tiny crabs and clams. The marsh is an important energy source for a variety of filter feeders in Long Island Sound.

Shell Island is one of the GLT's most visible properties.  It is a 5.23-acre island just off the Byram shore.  The island boasts sandy beaches, dramatic rock outcroppings, and dense woodlands.  Horseshoe crabs seek shelter on its shores, while shorebirds like the snowy egret stand tall in the shallow waters off the island, hunting for fish and crustaceans.  Julius Silver donated the island in 1990 with the stipulation that it be protected forever as a nature preserve.
