This small wooded valley with its spring-fed stream used to be a source of water for Felixstowe. Together with its small area of marsh, fen and adjacent heathland this reserve is good for flowering plants and a variety of birds including nuthatch, treecreeper, goldcrest and all three kinds of woodpecker.
Evocative nightingale song characterises the reserve in spring when you can find water avens and spectacular displays of marsh marigold alongside the stream. Careful scrutiny will also reveal common twayblade and the more open areas are covered in common spotted orchid. The woodland is dominated by oak, ash, alder, hazel and hawthorn.
