Extent & Distribution of UK Lowland
Wetland Habitats

 

The tables below give information on the extent (area covered) and distribution of lowland wetland habitats around the UK. Most extensive are lowland raised bogs, which are mainly spread across Northern Ireland, England and Scotland. A large part of this habitat is degraded bog capable of regeneration rather than active raised bog. Lowland fen mainly occurs in Wales, England and Northern Ireland. Knowledge of the extent of the various Lowland fen types recognised under the EU Habitats Directive Annex I types is limited.

 

UK BAP habitats

 

The table below shows the estimated extent the two lowland wetland priority habitat types recognised by the UK Biodiversity Action Plan. Values given are the overall total extent and percentage in each country, based on information extracted from the Biodiversity Action Reporting System (BARS).

EU Habitats Directive Annex I types

 

The table below shows the estimated extent of lowland wetland habitat types on Annex I of the EU Habitats Directive. The data is derived from the 2013 UK Report on Implementation of the Habitats Directive.  Note that for habitats that occur in both the lowlands and uplands, the area given is the total for both locations.
