British National Vegetation Classification

For the U.S. national vegetation classification, see United States National Vegetation Classification Standard.

The British National Vegetation Classification or NVC is a system of classifying natural habitat types in Britain according to the vegetation they contain. A large scientific meeting of ecologists, botanists, and other related professionals in the United Kingdom resulted in the publication of a compendium of five books (British Plant Communities ;ISBN 0-521-79716-0) by Cambridge University Press which detail the incidence of plant species in five major habitat types in the United Kingdom's natural environment. They are the first systematic and comprehensive account of the vegetation types of this country. They cover all natural, semi-natural and major artificial habitats in Great Britain (but not Northern Ireland), representing fifteen years of research by leading plant ecologists. From the data collated from the books, a commercial software product called Match [1] was developed which helps to classify vegetation identified into one of the many habitat types found in Great Britain. An alternative version, freely distributable under the GNU General Public License, called nvc-free is under development.

Communities by category

There are 286 communities in total in the British National Vegetation Classification. They are grouped into the following major categories:

• Woodland and scrub communities (25 communities, prefixed with the letter "W" — 19 classed as woodland, four as scrub and two as 'underscrub')
• Mires (38 communities, prefixed "M")
• Heaths (22 communities, prefixed "H")
• Mesotrophic grasslands (13 communities, prefixed "MG")
• Calcicolous grasslands (14 communities, prefixed "CG")
• Calcifugous grasslands and montane communities (21 communities, prefixed "U")
• Aquatic communities (24 communities, prefixed "A")
• Swamps and tall-herb fens (28 communities, prefixed "S")
• Salt-marsh communities (28 communities, prefixed "SM")
• Shingle, strandline and sand-dune communities (19 communities, prefixed "SD" — one shingle community, two strandline communities and 16 sand-dune communities)
• Maritime cliff communities (12 communities, prefixed "MC")
• Vegetation of open habitats (42 communities, prefixed "OV")

A full list of these communities, grouped into the above categories can be found at List of plant communities in the British National Vegetation Classification.
