Correspondences between UK Lowland Grassland Habitats Types

 

The table below shows how the different lowland grassland 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 Lowland Grassland Habitats may belong to other habitat types. For more detailed information see the NBN dictionary of habitat correspondences interactive spreadsheet.
