The Studland and Godlingston Heath National Nature Reserve has a variety of habitats including heathland, bogs, woodland, alder and willow carr, sand dunes, scrub and freshwater, which support a variety of wildlife including large populations of wildfowl and insects. Studland Bay is particularly good for sighting rarer grebes and divers in winter, with up to 20 black-necked grebe and 5 great northern diver recorded. The Studland Peninsula is one of the best places to see Dartford warbler in the UK with around 130 pairs nesting on the heath; this is about 7% of the UK population. The nature reserve is one of only a few places (mostly in Dorset) in Britain which is home to all six native reptile species.
