Originally noted as a small area of fen and fen carr (wet woodland) close to the river, Tuddenham Fen is still in existence today and is included in the much larger Cavenham Heath National Nature Reserve (NNR). Much of the site is dry, acidic heathland, although the proximity of the river allows for some damper habitats including fen, wet meadows and willow scrub. Such diverse habitats attract a wide range of birds including whinchat, wheatear, hen harrier, woodlark and stone curlew. Now managed by Natural England.
