Arne RSPB reserve about 4 miles from the centre of Wareham. It was established in 1965 and is part of the Purbeck heaths covering approximately 535 hectares.
Directions - heading south from Wareham over the causeway to Stoborough and via Nutcrack Lane follow the signposts to Arne and the car park is located at the beginning of the village.
In addition to the open areas of heathland the reserve includes old oak woodland, saltmarsh and open stretches of water across Poole harbour. The reserve is a good place to see the Dartford Warbler. Over the winter the saltmarsh areas / Middlebere Lake attracts a good variety of waders and wildfowl that can number in excess of 25,000 birds during January and Februrary.
