Newdigate Brickworks Nature Reserve, managed by Surrey Wildlife Trust, is a disused clay pit which now hosts two lakes and a series of smaller ponds. These are home to a variety of aquatic wildlife including Great crested newts, broad bodied chaser and emperor dragonflies. The water bodies attract a good range of wetland birds including kingfishers and snipe.

The site also contains areas of woodland and scrub that include hawthorn, wild cherry, apple, alder, sessile oak, blackthorn, hornbeam and elder. There are also some specimens of the wild service tree. The mosaic of woodland, scrub, grassland, marsh, water-side and aquatic vegetation communities makes the site particularly diverse.
