Boyton Marshes is a nature reserve located in the English county of Suffolk. The reserve is managed by the Royal Society for the Protection of Birds (RSPB) and covers an area of approximately 260 hectares.
Boyton Marshes is an important wetland habitat, consisting of saltmarsh, freshwater marsh, and intertidal mudflats. The reserve is home to a wide
variety of plant and animal species, including wading birds such as avocets, redshanks, and curlews, as well as ducks, geese, and swans. Mammals that can be found in the reserve include otters and water voles, and the area is also home to a range of invertebrates, including butterflies and dragonflies.
The RSPB approached Valencia Communities Fund to massively expand the wetland through the creation of new lagoons in two phases, totalling £87,000. The resulting works contributed to the creation of 5.5ha of new freshwater marsh edges, water-control sluices, and new islands.
