Correspondences between UK Lowland Wetland Habitat Types

 

The table below shows how the different lowland wetland 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.
