Designation can be used to protect areas of value and scientific interest and to ensure that such areas are properly managed. This includes areas of particular value for the conservation of species, habitats, historic and cultural assets and landscapes of great value or beauty.
Designation is driven by a goal to conserve and enhance such areas and is underpinned by UK and international legislation. Development within or near designated areas is subject to additional controls.
SSSI's were first established in 1949 by the Nature Conservancy so that the conservation of important sites of natural habitat, wildlife and geological heritage could be taken into account during the planning process. Today, Natural England has responsibility for identifying and protecting SSSIs in England under the provisions of the Wildlife and Countryside Act.
SSSI’s include sites such as:
- Ancient woodlands.
- Species-rich grasslands.
- Coastal marshes and mudflats.
- Unique geological formations.
