About the reserve

A wildlife haven in a corner of Cassiobury Park, close to the bustling heart of Watford. The wet habitats found in Cassiobury Park Local Nature Reserve were once shallow watercress beds, fed with water from the river through a series of ditches. These have developed into marshland and open pools, surrounded by wet woodland of alder and willow, providing valuable cover and nesting sites for birds. There are also areas of grassland where birds such as goldfinch and greenfinch feed on the seedheads of thistles and teasels. Cassiobury Park is managed by Herts and Middlesex Wildlife Trust in partnership with Veolia Environmental Services and Watford Borough Council.
