About the reserve
This beautiful reserve contains a variety of habitats including wet meadow, tall fen and swamp, alder carr, willow scrub, willow pollards and chalk stream. The tall fen/swamp occurs around a lagoon and along adjacent channels, and has a mixture of common reed, reed sweet-grass and common reedmace. Water voles can be seen swimming in the reedbed channels. The surrounding banks support great horsetail, butterbur and moschatel, as well as greater and lesser pond sedges, monkey flower and golden saxifrage. Cetti’s warblers are breeding –
