  • Natural Resources Wales monitors bathing water sites identified under EC Bathing Waters Directive 2006/7/EC in Wales. Samples are taken throughout the bathing season from May to the end of September and analysed for two parameters: Escherichia coli and intestinal enterococci. A classification of bathing water quality, generally based on 4 years of sample results, is produced for each bathing

  • This GIS dataset and supporting information providing design / extreme sea level and typical surge information around the coastline of Wales under present day conditions. This is a specialist dataset which informs on work commenced around the coast ranging from coastal flood modelling, scheme design, strategic planning and flood risk assessments. The dataset contains the following layer

  • 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

  • This is the most up-to-date version of the marine Biodiversity Action Plan (BAP) spatial datasets held by Natural Resources Wales (NRW). The UK Biodiversity Action Plan (UK BAP) was published back in 1994, and was the UK Government's response to the Convention on Biological Diversity (CBD), which the UK signed up to in 1992 in Rio de Janeiro. Similarly under Section 42 of the Natural Environment

  • In 2015 the Marine Nature Reserve changed designation to Marine Conservation Zone (MCZ). This spatial dataset contains the digital boundaries of Marine Conservation Zones (MCZs) former Marine Nature Reserves in Wales. MCZs and MNRs are a way of conserving marine habitats and wildlife and other features, of special importance, along the shore or on the seabed. Skomer, the first and only MNR in

  • These records contain coordinate data associated with current marine licence applications in Wales. The location of disposal sites is also available. This data allows the locations of licence applications to be mapped to assess their impacts on designated sites and in combination effects with other proposals.

  • NRW agreed, identified and documented which habitats and SAC features are sensitive to a range of Marine Licencing Band 1 activities. The dataset consists of 2 layers detailing information about sensitive habitats. These datasets constitute polygons derived from NRW held BAP (Section 7) / OSPAR layers, Regulation 35 SAC habitat layers and Phase 1 intertidal survey. All the habitats included in

  • The Regulation 35 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 also form the baseline against which we measure

  • This dataset is a more detailed version of the Coastal Erosion data also available on Lle (Link). 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

  • 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

  • Natural Resources Wales Species data held on the National Biodiversity Network (NBN) Gateway. This includes marine, terrestrial and freshwater species records for a variety of taxonomic groups. Data was collected to support core NRW functions including statutory and non-statutory reporting, condition monitoring and decision making.

    The NBN key portal is the main route for the publishing NRW

  • The Convention for the Protection of the Marine Environment of the North-East Atlantic known as the OSPAR Convention 1998 (Oslo Convention 1972 & Paris Convention 1974), is an agreement signed by a number of European countries (including the United Kingdom) to protect the quality of the North East Atlantic. The objective of the OSPAR Convention is to take all possible steps to prevent and

  • GIS layers showing the abundance and distribution of seabirds in welsh waters. The datasets consist of the raw data showing observations of all seabirds and derived grids showing the density of flying and sitting species on a 3km grid scale and the survey coverage. The purpose of this data capture was to collate data from ESAS and WWT Consulting databases to produce combined database of birds

  • The datasets shows the spatial coastal baseline which is split into ‘frontages’. These are defined as lengths of coast with consistent characteristics based on the cliff behaviour characteristics and the defence characteristics. It is intended as a benchmark dataset showing erosion extents and rates for three periods:

    • Short Term (0 – 20yr);
    • Medium Term (20 – 50yr); and

  • Special Areas of Conservation (SACs) and Special Protection Areas (SPAs) are protected and designated sites under the EC Habitats and Birds Directives. The Directives list habitat types and species that are considered to be most in need of conservation at a European level. An obligation for this is a programme of species and habitat monitoring across the site. This dataset shows the results of
