Correspondences between UK Upland Habitat Types

The table below shows how the different upland habitat types recognised by the mainstream habitat classifications in the UK relate to each other. The types included are those recognised under the UK Biodiversity Action Plan (UK BAP), the EU Habitats Directive, and the British National Vegetation Classification (NVC).

 

The table shows only how the types broadly fit together – some examples of the types shown may fit into other vegetation/habitat types. For more detailed information see the NBN dictionary of habitat correspondences interactive spreadsheet (though not all the types shown below are covered by this).

 

Click on the links to access the definitions of the UK BAP and EU Annex I types. The definitions of the NVC types are available in the five-volume publication entitled British Plant Communities, with summary information given in the Illustrated Guide to British Upland Vegetation and the NVC field guide to mires and heaths.
