This is a rare example of an Essex fresh water grazing marsh, worked for decades by traditional methods sympathetic to wildlife. Owned by Essex Wildlife Trust, it is grazed by the Trust's own rare breed sheep and cattle. Wildlife is abundant in its 600 acres of rough pasture, borrowdykes, seawalls, wet flushes, pools and saltmarsh.
Dry grassland on the slopes of the seawalls supports a wide variety of insects, including butterflies, bush-crickets and grasshoppers. In spring spiny rest-harrow, grass vetchling, slender hare's-ear and many other wild flowers can be found in ungrazed areas.
Borrowdykes trace the inland edge of the sinuous seawall for its entire length. Common reed, sea clubrush and fennel pondweed are typical plants of these brackish areas where reed warbler and reed bunting nest in spring, and heron and little grebe search for food. Wet flushes, dykes and small pools in the pasture support aquatic plants such as water crowfoot, and breeding populations of dragonflies and other aquatic species.
Outside the seawall, creeks, saltmarsh and exposed mud support typical communities of invertebrates, coastal birds and saltmarsh flowers. The shingle spits have yellow horned-poppy, and also a small breeding colony of little terns.
The main pillars of management are water level control and getting the right level of grazing to create good conditions for wildlife

Sheep ticks can be a problem in April–June: keep out of the long grass or wear light-coloured (so the ticks can easily be seen) long trousers for protection. Leaflets from Essex Wildlife Trust visitor centres. For more information call the warden on 01621 868628.
