Living marine flora and fauna can play a valuable role in the defence of coastal regions i.e. distubance prevention. Marine ecosystems and the presence of organisms in the front line of sea defence can dampen and prevent the impact of tidal surges, storms and floods providing a 'buffering' effect that protects humans from the effects of these destructive perturbations. This disturbance alleviaion service is provided mainly by a diverse range of species which bind and stabilise sediments and create matural sea grass defences, for example salt marshes, mangrove forests and sea grass beds (Huxley, 1992[1]; Davison & Hughes, 1998[2])
