Over 100 species of bird, including the Grey Herons with their thriving heronry and woodpeckers, are recorded annually. The beautiful Kingfisher is to be seen most days and is joined by Common Terns in the summer which come to breed on the millpond.

The four hides and the feeding station provide closer views of the wildlife. Whether visiting to enjoy a relaxing walk and tranquillity or as keen birder or photographer the Reserve will not disappoint.
Prior to becoming a nature reserve, the millpond and surrounding land has a interesting heritage. The Warnham mill and millpond have existed in different forms for many centuries with earliest records suggesting a mill existed in the 13th century. It was during the 16th century, when the iron industry flourishing in the Weald, that the millpond was created as a ‘hammer pond’ to provide power for a blast furnace and hammer. It is reputed that the iron was used to make cannons for the battle leading up to the Spanish Armada. During the Civil War the iron mill was destroyed by Cromwell’s troops. Later in the same century a flour mill was built which used an enlarge millpond as the source of power. There has been a mill on the site ever since and the present mill dates from the 19th century and remained in use until the 1930’s.
The Reserve has connection with the poet Percy Bysshe Shelley who was born in Warnham. It is said that as a young man he learnt to sail on the millpond and had a favourite picnic spot under a Sweet Chestnut on the edge of the Reserve. Later the land, now covered by the Reserve, was owned by his son, Sir P F Shelley, who sold it to the Lucas family to become part of the Warnham Estate in 1875. It remained so for over 100 years until the early 1980’s when the A24 was upgraded to a dual carriageway, which physically separated it from the main estate. The land was then purchased by Horsham District Council and the 92 acre site was designated a Local Nature Reserve in 1988. It is managed by the council’s Parks and Countryside Services team.
Sorry, DOGS and CYCLING are not permitted on the Reserve and food is restricted to the Visitor Centre, courtyard and picnic area.
