About the reserve
The rare and haunting bittern and flighty bearded tit are found here. A secluded landscape of grazing marsh intersected by a series of dykes and tree belts – a good example of how industry and conservation can work together.
This diverse site is one of the best wetlands in East Anglia for wildflowers; it is a stronghold for otter, water vole and kingfisher, whilst water rail and barn owl can often be seen. The wildflower meadows, which are maintained by cattle and sheep grazing, include four species of orchid, yellow rattle, ragged-robin, bogbean and lady’s smock.
In summer the dykes are alive with many dragonfly (17 species have been recorded) including hairy and migrant hawker dragonfly. Visiting birds like wigeon, snipe and shoveler are attracted to the flooded marshes during winter.
