APPENDIX C
Criteria for selecting Sites of Importance for Nature Conservation in Hampshire
 
The criteria below define those sites which are considered to be of particular importance for nature conservation within Hampshire. These sites are in addition to the statutorily designated sites and are referred to as Sites of Importance for Nature Conservation (SINCs).
 
Woodland
1A Ancient 1 semi-natural 2 woodlands.
1B Other woodland where there is a significant element of ancient semi-natural woodland surviving.
1C Other semi-natural woodland if they comprise important community types of restricted distribution in the County, such as yew woods and alder swamp woods.
1D Pasture woodland and wooded commons, not included in any of the above, which are of considerable biological and historical interest.
 
Neutral/acid/calcareous grassland
2A Agriculturally unimproved grasslands 3.
2B Semi-improved grasslands which retain a significant element of unimproved grassland.
2D Grasslands which have become impoverished through inappropriate management but which retain sufficient elements of relic unimproved grassland to enable recovery.
   
Heathland
3A Areas of heathland vegetation, including matrices of dwarf shrub, acid grassland, valley mires and scrub.
3B Areas of heathland which are afforested or have succeeded to woodland if;
  (i) they retain significant remnants of heathland vegetation which would enable their recovery, or
  (ii) they are contiguous with, or form an integral part of, an open area of heathland.

Coastal habitats
4A Semi-natural coastal and estuarine habitats, including saltmarsh, intertidal mudflats, sand dunes, shingle, brackish ponds, grazing marsh and maritime grasslands.
   
Wetlands
5A Areas of open freshwater (e.g. lakes, ponds, canals, rivers, streams and ditches) which support outstanding assemblages of floating/submerged/ emergent plant species, invertebrates, birds or amphibians.
5B Fens, flushes, seepages, springs, inundation grasslands etc. that support a flora and fauna characteristic of unimproved and waterlogged (seasonal or permanent) conditions.
   
Species
6A Sites which support one or more notable species.
6B Sites that regularly support a significant population of a species, which has a restricted distribution or has substantially declined in population or range. Such sites may be used seasonally or for only one part of a species life cycle.
6C Sites that support an outstanding assemblage of species.
   
Social Value
7A Sites of nature conservation interest which occur in areas otherwise deficient in such interest, and/or are known to be of particularly high value to local communities e.g. Community wildlife sites.
   
Geology and geomorphology
8A Sites which have been designated as Regionally Important Geological/ Geomorphological Sites (RIGS) are sites of regional importance excluding SSSIs. RIGS are analogous to biological non-statutory sites.
 

1. "Ancient" refers to woodlands, which have developed particular ecological characteristics as a result of their long continuity. Those identified to date, which are over 2ha are included on the Hampshire Inventory of Ancient Woodlands (provisional).

2. "Semi-natural" refers to modified types of vegetation in which the dominant and constant species are accepted natives to Britain and that locality, and the structure of the community conforms to the range of natural vegetation types.

"Agriculturally unimproved grasslands" is grassland that is composed of a mixed assemblage of indigenous species in essentially semi-natural communities which have been allowed to develop without the major use of herbicides or inorganic fertilizers.
