About the reserve

This nature reserve is a great place to see several rare plants that are now only found at a few sites in the county, such as Southern Marsh Orchids, Marsh Willowherb and Marsh Valerian.

Work has been undertaken to open up the numerous ditches, which has allowed Water Voles to successfully establish in them from further up the River Stort. 

The surrounding areas of tall sedge and reedbeds provide a valuable nesting habitat for both Reed and Sedge Warblers and an abundance of invertebrate species.
