The HABMAP project was set up in response to the need for better spatial awareness of habitat distributions in the Southern Irish Sea. This work produced habitat maps of the seabed using novel predictive modelling techniques. The HABMAP Extension Project has built on the methods developed during the original project, and has repeated the modelling work using higher resolution / improved input

This is a dataset compiled of spatially-referenced survey data obtained from different intertidal communities (biotopes) in Wales. Maps include information on biotope location, target note location, access and photographs points locations. Sites are mapped once and therefore are a 'snapshot' in time. Survey methodology is based on 'Handbook for Marine Intertidal Phase 1 Biotope Mapping Survey'.

The Habitats Directive Article 17 reporting maps are a snapshot of the most up to date spatial data for features listed on the various Annexes of the Directive at the time of reporting. They represent the current known extent / location and status of features both inside and outside of SACs. Article 17 maps are reviewed and updated every 6 years as part of the Habitats Directive reporting

The Regulation 37 (formally 35 and 33) Special Areas of Conservation (SAC) feature maps provide the indicative baseline extent and status (i.e. “Definite” or “Potential” feature status and / or confidence) of SAC features at the time of site designation. These are the maps that should be used to assess potential impacts of plans and projects and for casework advice. They

All survey work was completed by ABPmer on behalf of Welsh Government. Two areas were chosen for the survey work off covering two broad geographical areas, St David’s Head, Pembrokeshire; and an area to the west of Anglesey. Surveys were conducted during July and August 2019. When collecting multibeam data, an appropriate overlap was maintained to ensure that 100% coverage is achieved

This dataset is a more detailed version of the Coastal Erosion data also available on Lle. The National Coastal Erosion Risk Management (NCERM) map shows the spatial NCERM coastal baseline. This baseline is split to ‘frontages’. These are defined as lengths of coast with consistent characteristics based on the cliff behaviour characteristics and the defence characteristics. It is

Seascapes, like landscapes, reflect the relationship between people and place and the part it plays in forming the setting to our everyday lives. Marine Character Areas highlight the key natural, cultural and perceptual influences that make the character of each seascape distinct and unique. NRW were commissioned on behalf of Welsh Government to identify the character of Wales’ seascapes at
