Dorset, England, rests on a variety of different rock types which give the county its interesting landscapes and habitats. Dorset is particularly noted for its coastline, the Jurassic Coast, which in 2001 was designated a World Heritage Site because of the variety of landforms and fossils exhibited along the coast. 44% of the county is within the Dorset AONB, which includes most of the Downs, Blackmore Vale, Purbecks, the Chesil Beach and Fleet SSSI and Poole Harbour.
