Dover to Deal

Site overview: This is 10km2 site has within it a narrow band of in chalk. The chalk forms reefs, ledges and gullies which are part of an almost continuous chalk reef between Kingsdown, Deal in the north-east and Folkestone Warren in the south-west. The chalk is in the form of a gently sloping platform, with gullies up to two meters deep and rock pools on the seaward side, supporting a huge diversity of marine plants and animals. Farther offshore, the chalk gradually becomes covered in coarse sediments. Here, thousands of sandy tubes made by tiny ross worms form significant reefs which can harbour a wonderful diversity of wildlife. The naturally eroding chalk cliffs give rise to boulder strewn shores and shaded habitat for unusual sponges and sea squirts. The chalk platform extends across the shore and out to sea, with deep sand filled gullies between tall ridges of chalk covered in seaweeds, sponges and anemones. Large crabs and lobsters find shelter within the chalk in recesses, while baby cuttlefish swim around the outcrops, demonstrating their amazing camouflage.
