Palaeo-environmental | relating to the changes of the environment through prehistory and history, particularly the more distant past. |
Physical Processes | coastal phenomena such as sediment transport, erosion and accretion responsible for shaping the coast and underpinning its dynamic qualities. It refers to geological/earth science processes only. |
Planning Policy Guidance | a series of notes issued by the Department of the Environment setting out the Government’s policy guidance on planning issues, such as the countryside, nature conservation, archaeology, development etc. |
Pollution | the addition of materials or energy into the existing environmental system to the extent that undesirable changes are produced directly or indirectly in that system. |

Preliminary Treatment | physical treatment of effluent by screening and grit removal. |
Primary Treatment | physical treatment of effluent by screening and settlement. |
Ramsar Site | The Convention on Wetland of International Importance, especially as wildfowl habitat was adopted at a meeting held at Ramsar in Iran. The UK Government in signing the convention in 1973 designates wetlands in accordance with agreed criteria. A wetland is regarded as internationally important if it regularly supports 20,000 waterfowl or 1% of a species, or sub-species of waterfowl. |

Roman | AD 43 - c. 410. |
Rural | land outside of the settlements. |
Saltmarsh | a coastal marsh found along low-lying shores, usually protected by a spit, an expanse of mudflat or in the sheltered part of an estuary, colonised by plant species capable of withstanding frequent and often prolonged immersion in saltwater. |
Sea Defences | anything natural or artificial that prevents the ingress of land by sea. |
Secondary Treatment | biological degradation of effluent which has already received primary treatment. The process may also involve some chemical and physical treatment. |
Sediment | deposited particles or grains of rock. |
Set-aside | land removed from food production as part of the Common Agricultural Policy (CAP) reform. |
Sewage | liquid waste matter from domestic or industrial source that is carried in sewers or drains (sewerage) to a sewage treatment works (STW). |
Sewage Sludge | the solid constituents of sewage that are removed for subsequent purification. |
Shoreline Management Plan | plans through which local authorities and others provide a framework for sustainable coastal defence policies within a sediment cell or sub-cell. |
Siltation | at low velocities water will deposit the material being carried in suspension. The slower the velocity the finer the material deposited. |
Site of Importance for Nature Conservation (SINC) | areas of land and wetland of local importance for the conservation of semi-natural habitats including mosaics of heathland, unimproved grassland, scrubland and plantation and/or habitats which support rare local wildlife species. They are not of sufficient extent or quality to qualify for national recognition as a SSSI. |
SSSI, Site of Special Scientific Interest | an area of land which in the opinion of English Nature is of special interest at a national level due to its flora, fauna or geological or physiographical features. EN provide notification to owners, occupiers, local planning authorities and the Secretary of State under the provision of Section 28 of the Wildlife and Countryside Act, 1981. |
SAC, Special Area for Conservation | areas of open water or land of international importance designated by the UK Government to comply with the requirements of the EC Habitats & Species Directive. To conserve natural habitats and wild fauna and flora, which are considered rare or endangered and are recognised as being under a particular threat. Nationally implemented under the Habitat Regulations, 1994. |
SPA, Special Protection Area | an area designated by the UK Government to comply with the requirements of the EC Directive of 1979 on the Conservation of Wild Birds. Member states are required to take special conservation measures concerning the habitat of species of wild birds listed in Annex 1 of the Directive (certain rare and vulnerable species) and of regularly occurring migratory species where particular attention needs to be paid of wetlands, especially those of international importance. These measures include classifying the most suitable localities as SPAs and taking appropriate steps to avoid pollution or deterioration of the habitat or disturbance affecting the birds. Nationally implemented under the Habitat Regulations, 1994. |
Sustainable | capable of being maintained at a steady level without exhausting natural resources or causing severe ecological damage. |
Sustainable Development | balancing the need for development and growth against the need to protect the natural and built environment whilst meeting the needs of the present generation without compromising the needs and aspirations of future generations. |
