      • Human activity destroys habitats
      • The marshes are a site of special scientific interest and are a nature reserve
    • Under threat
      • Retreating up to 6m a year
      • Sea level rising and the marsh being squashed against a sea wall
      • In December 1989 50-80m exposed to storms eroded in less than three months
    • Defences
      • 1996- rock armour introduced
      • Beach nourishment used to increase the height and width of the beach
    • Sustainable solution
      • Marshes haven't been eroded since defences put in place
      • Spit hasn't breached
      • Still a problem with rising sea level and the sea wall
