Local Sites – Geosites

Important natural history sites in the UK can be given statutory protection (i.e. in law) by being designated by Natural England as Sites of Special Scientific Interest (SSSIs). This designation can be given for biological or geological value. There are 10 sites in Cambridgeshire that are geological SSSIs. There are many other sites that have geological value and these can be designated as Local Geological Sites (LGS). Previously called RIGS (Regionally Important Geological Sites) and also referred to as Geosites, these sites, and the protection of their geodiversity, need to be considered within the planning system. Our Geosites initiative was launched at the beginning of 2010 with one of its main aims being to obtain LGS designation for sites in the county that are of geological interest for their scientific, educational, historical or aesthetic value.

Geological SSSIs in Cambridgeshire

The 10 sites in the county which currently have SSSI designation for geological value are Roswell Pits near Ely, Shippea Hill in East Cambs, Traveller’s Rest Pit in Cambridge, Adventurer’s Land in Fenland, Upware South Pit, Upware Bridge North Pit, two pits at Barrington in South Cambs, Histon Road in South Cambs and Eye Green Pit near Peterborough. Others, including Warboys Clay Pit, have been denotified as SSSIs as they have lost their geological value. Most of these sites have limited or no access and it may also be very difficult to see the geological interest. Some are working pits and safety is an issue. 

Local Geological Sites (LGS) in Cambridgeshire

We have recently been successful in getting Local Geological Site designation for East Pit in Cherry Hinton, a very important chalk site and also for Nine Wells, one of the characteristic chalk springs found in the south of the county. Both sites are open to the public and are safe to visit. East Pit is a nature reserve and biological SSSI owned and managed by the local Wildlife Trust and Nine Wells is a Local Nature Reserve managed by Cambridge City Council.

We are working to designate sites that can tell the story of the geological history of Cambridgeshire, linking this local heritage to the rest of the UK and worldwide geology. Many of these sites are likely to have public access and can be used by community groups and the general public to enjoy discovering their local landscape.

For further information on Local Geological Sites, see this leaflet produced by GeoConservation UK.

Some of the key Geosite objectives are:

  • Listing of potential and known existing sites
  • Studying the geological and geomorphological history of the sites
  • Studying the use and cultural aspects of each site, including its setting in the landscape
  • Establishing the ownership and current use and management of the site
  • Visiting each individual site to carry out surveys if access allows
  • Proposing suitable sites for designation and liaising with landowners and managers
  • Preparing a listing of fossil types for each site
  • Providing information on the sites via leaflets and websites
  • Maintaining a record of sites and their management
  • Providing assistance in preserving and conserving key sites of interest

To achieve these and other objectives we need many volunteers to help make this project a success. So, if you are interested in helping, please do contact us. We welcome both amateur and professional volunteers. For further information contact us.
