  • Soft engineering- Sefton coast, northwest England
    • Reasons for protecting
      • Sand dune area extending 17kms (largest in England)
      • Sand dune system at Formby Point lost 700m between 120 and 1970
      • Natural erosion levels accelerated by spoil dumping, dredging and construction of Liverpool and Preston ports
      • Open access for tourists with off road vehicles destroying vegetation
      • Sand is removed for foundry trade and glass polishing
    • Objectives of scheme
      • Close monitoring of visitor numbers
      • Prohibiting use of off road vehicles
      • Controlling extraction  of sand for commercial uses
      • Removing pine plantations and scrub to re-establish a spectrum of habitats
    • Benefits
      • Re-colonisation of specialised plants such as yellow bartisia and animals such as sand lizard
      • Re-established and maintained habitats including bare dunes and trees suitable for a wide range of associated species
      • Mobile dunes and associated plants would increase the biodiversity of the area and return the soils to a natural conditions
      • Reduce fire risk
    • Success?
      • It may be difficult to balance recreational activities and ecosystems
      • The Sefton coastline is very active
      • The pressure on the coastline may increase physical changes
    • Costs
      • Colonies of red squirrels are threatened due to the removal of the pine plantations
      • Difficulty managing the increased tourist visitor numbers particularly during the summer months
      • Continued erosion of Formby Point
