The sea wall was built two centuries ago - claiming land to graze sheep. Today, however, rising sea levels threaten these man-made barriers and we're enabling nature to take back the shoreline it requires to soften the power of the tides and to act as a buffer between sea and land.
The Essex marshes offer a taste of wilderness when you want to get away from the hustle and bustle of modern living. Whether you're a photographer, artist or just out for a walk, you'll enjoy yourself.
Insects and wild flowers
Our diverse farmland and salt-marshes are a prime habitat for wildflowers and insects like bees, so we manage nectar-rich field margins and encourage wildflower growth in fields. We're also home to scarce and less friendly species like adders too.
Dogs under control are welcome, all we ask is that you help us care for Copt Hall's wildlife by using the signed routes and paths. In the winter months we see the return of the winter birds who thrive on the farmland at Copt Hall. By keeping your dog on the lead at this time, you will be helping to secure a healthy future for these birds. . Why not blow away the cobwebs and enjoy a walk along the seawall?
Birds, birds and more birds
The Blackwater Estuary is home to a wide range of farmland and coastal birdlife. The most visible presence are the thousands of birds like Brent geese who call us home during the winter months, making Copt Hall a habitat of national importance. Scarcer species include barn and short-eared owls, kestrels and marsh harriers. Don't miss the vantage point from our bird hide.
During the First World War, 24 September 1916 was a memorable date for Copt Hall when a German L33 super-Zeppelin crashed here. Returning from a bombing raid over London's East End, the Zeppelin was attacked by the RAF above Chelmsford and came down within feet of a farm labourer's cottage.
