Hartland Moor is a Site of Special Scientific Interest (SSSI) on the south side of Poole Harbour near the town of Wareham in Dorset, England.

[1] That designation applies to 243 hectares (600 acres) of the site;[2] it is part of a larger area that was notified as an SSSI in 1986.

All six British reptile species are present on the site;[3] the rare sand lizard and smooth snake both breed on the property.

[1] The site is grazed by a herd of Red Devon cattle that help to keep scrub vegetation from taking over the habitat.

[3] Gorse found on the dry heath provides habitat for the European stonechat and the rare Dartford warbler,[1] which is only present on a few sites in the United Kingdom.
