The emphasis now placed on the concept of sediment cells as
boundaries for coastal defence groups, and the development of SMPs,
should help CPAs realise the importance of natural processes at the
coast when designing defence and protection schemes. However, this
will only be the case where defence groups exist, and where CPAs
take up the challenge of developing SMPs. Coastal landscapes have
been produced by the natural forces of wind, waves and tides, and
many are nationally or internationally important for their habitats
and natural features. Past practices at the coast, such as the
construction of harbours, jetties and traditional defence systems
may have contributed to the deterioration of the coast. English
Nature (1992) have argued that if practices and methods of coastal
defence are allowed to continue, then coastlines would be faced
with worsening consequences, including: The loss of mudflats and
the birds which live on them Damage to geological Sites of Special
Scientific Interest (SSSIs) and scenic heritage by erosion, due to
the stabilisation of the coast elsewhere Cutting of sediment
supplies to beaches resulting in the loss of coastal wildlife
Cessation through isolation from coastal processes, of the natural
operation of spits, with serious deterioration of rare plants,
animals and geomorphological and scenic qualities (English Nature,
1992) A number of designations, provided by national and
international legislation do exist to aid conservation.
