This dataset was part of the Phase 2 Habitats surveys conducted across Wales. It consists of a detailed survey of plant communities in lowland peatland vegetation. The primary objective of the survey is to characterise and evaluate the vegetation cover of lowland peatlands in Wales to ensure the identification, protection and management of important peatland sites. Entire dataset has been extensively validated and verified by NRW vegetation survey specialists. Habitat composition may change over time due to successional trends, land management or even planned developments. A record of a vegetation type or species in the digital data is therefore no guarantee that it is still extant on the ground.

This National Vegetation Classification (NVC) Phase 2 project and corresponding datasets are a collation of mapped saltmarsh habitats across Wales. This data was collected to provide an overview of saltmarshes across Wales. The surveys were conducted between 1990 and 2003. The dataset has been extensively validated and verified. However, habitat composition may change over time due to successional trends, land management or even planned developments. A record of a vegetation type or species in the digital data is therefore no guarantee that it is still extant on the ground.

This is a spatial dataset containing a collation of all mapped sand dune habitats in Wales. Over 40 NVC Phase 2 surveys were carried out on sand dunes across Wales. This dataset is a collation of data from these surveys grouped together for mobilisation purposes and to provide information on a Wales-wide scale. The purpose of this data capture was to help define the sand dune vegetation resource of Wales. Habitat composition may change over time due to successional trends, land management or even planned developments. A record of a vegetation type or species in the digital data is therefore no guarantee that it is still extant on the ground.

This dataset holds comprehensive habitat cover data for the whole of Wales derived from a programme of field recording that was begun by the Wales Field Unit of the Nature Conservancy Council in 1979 and continued by the Countryside Council for Wales after restructuring in 1991. The purpose of this data capture was to inform site selection, casework and policy decisions. The fieldwork was conducted in two main stages. Most upland areas were surveyed during the first stage (the Upland Vegetation Survey), and areas were assigned to habitat types using the Ratcliffe and Birks classification. The rest of Wales including all the lowlands and some previously unsurveyed upland areas was covered during the second stage (the lowland phase), and habitats assigned to the Phase I classification, with some minor modifications adopted for use in Wales. This datasets contains the following layers: Vegetation Voronoi: Showing the boundaries and attributes of vegetation polygons with upland mixed habitat polygons subdivided into their component habitats Habitat: Point data showing the location of habitats mapped in mixed habitat polygons during the Upland Vegetation Survey Mospolys Voronoi: A grid coloured in chequerboard fashion according to Phase1_Code and in proportion to their extent to enable the visualisation of mosaics Mosnotes Varanoi: Point data to describe habitat composition of mosaic polygons Scattered Vegetation: point data showing the location of scattered vegetation Target Notes: record the position and reference number of Phase 1 target notes Mosaic Voronoi: Browser table to supply habitat types, areas and proportions for mosaic polygons See the metadata for more detail.

Under the Environment (Wales) Act (2016), Section 7 requires biodiversity lists to be produced. These lists include types of habitats which are of "Principle Importance" for the purpose of maintain and enhancing biodiversity in relation to Wales. This list supersedes the duty in Section 42 of the NERC Act 2006. This dataset details the extent and location of those terrestrial habitats classed of "Principle Importance" in Wales. This dataset was created using Priority Habitats of Wales Local Biodiversity Action Plan (LBAP) and Broad Habitats both of which are derived from Phase 1 Terrestrial habitat and species surveys conducted across Wales. In 2019 the interim list of habitats of principle importance was exactly the same as the previous list under Section 42 of the NERC Act. The current representation of Priority Habitats in this Environment (Wales) Act Section 7 Terrestrial Habitats of Principle Importance catalogue entry on DataMapWales is incomplete. This is because of an ongoing review of the data. We anticipate releasing the complete updated version of the data later this year (current estimated completion date is December 2024 but this may change). If you require a specific Priority Habitat, please contact us at opendata@cyfoethnaturiolcymru.gov.uk, and we may be able to provide you with the relevant data, if it’s in a condition to do so. This will be with the caveat that the data is draft and may change. Attribution statementContains Natural Resources Wales information © Natural Resources Wales and Database Right.

Heatmaps (geodatabases) were created for invasive non-native species pathways in Welsh waters including commercial shipping, recreational boating, aquaculture, fishing and offshore activities. Heatmaps were produced at both 2km x 2km and 5km x 5km resolutions and have associated symbology layers. An overall heatmap was also produced to highlight key areas which are likely most at risk from invasion of invasive non-native species. This assessment provides a valuable insight into hotspots related to each potential pathway of introduction, the areas where the main areas of risk overlap for the different pathways and their overlap with protected areas. The outputs from this assessment can form the basis to underpin biosecurity planning. It should be noted, however, that this was a national scale mapping exercise based only on freely available datasets, which themselves have limitations and possible inaccuracies due to incomplete coverage, both temporally and spatially. The scorings applied to the input datasets and weightings applied to the introduction pathways are also based on available literature and expert judgement. Site-specific activities and conditions will always be an important consideration, as well as temporal variations.

Modelled Distributions and Abundance of Cetaceans and Seabirds of Wales and Surrounding Waters This is a dataset is of modelled maximum and monthly (mean) densities of certain cetacean and seabird species in the Irish and Celtic seas around Wales. Modelled densities are derived from predictive modelling of sightings and environmental variables. Maximum maps represent the maximum density per 2.5km2 cell from the entire dataset. Monthly (seabirds and cetaceans) and decadal (cetaceans only) maps are expressed as mean density per 2.5km2 cell. Modelled maximum data can be downloaded using Data Map Wales. For monthly (for seabirds and cetaceans) and decadal (for cetaceans only) data follow this link. Seasons (for seabirds and cetaceans) and Seasons by Decade and Decades (for cetaceans only) can be constructed by combining the relevant monthly maps in GIS For more information about the datasets and methods, please see the NRW evidence report here: 646: Modelled Distributions and Abundance of Cetaceans and Seabirds of Wales and Surrounding Waters (cyfoethnaturiol.cymru) Attribution statement Contains Natural Resources Wales information © Natural Resources Wales and Database Right.

To better understand opportunities to build resilience in the Welsh marine environment, Natural Resources Wales commissioned a report to identify potential spatial opportunities to restore valuable marine habitats. The report created spatial products (Arc Geo database) for: areas in the floodplain that might be suitable for the creation of mudflat and saltmarsh through managed realignment and areas where the right conditions might exist for native oyster habitat and horse mussel bed restoration. The horse mussel data was provided from JNCC. The report also addresses restoration potential for Sabellaria alveolata reefs although no spatial data was created for this habitat and seagrass habitat, but this was provided as a map image from JNCC. These spatial data layers should be considered as initial aides to identifying potential locations or areas but come with several limitations which have been discussed in the report. Any restoration projects should undergo further site validation and local engagement before proceeding with any specific site. A variety of source data was used and merged to create a selection of GIS Layers listed in the abstract to identify spatial opportunities for restoration of marine and coastal habitats and species.
Priority Ecological Network in the Terrestrial Environment Priority Ecological Networks (PENs) in the terrestrial environment are versions of the all-Wales habitat networks that show areas of connectivity between Protected Sites, and as such provide a framework to inform the location of action to build functional resilient ecological networks based on our most important places for biodiversity. Typical actions would be habitat improvement, restoration, or creation, located within the boundaries of a PEN, or situated at its margins to consolidate, extend, or link different PENs. These PENs supersede the GIS layers that were previously known as ‘Level 2 networks’, and are available for: Native woodland; Semi-natural grassland; Heathland; Bog; Fen and Sand Dune All these priority networks are also represented as a ‘PEN Hotspot’ map, which is a simple count of all available networks within a given 1km square for an ‘at a glance’ view across Wales. In addition, the ‘native woodland’ and ‘semi-natural grassland’ PENs have both received updates in the form of additional networks to accommodate our latest protected sites series and survey information and expand beyond what was originally available. Heathland, Bog and Fen have been merged from their originally separate upland and lowland versions into singular datasets and a previously unreleased ‘sand dune’ network is also now included. A Freshwater PEN is planned. Please note: These individual map layers are a modelled description of current connectivity between habitats and as such should be considered as descriptive, rather than prescriptive! As well as this set of priority networks, it is useful to also be able to view these layers alongside other open datasets available for download from DataMap Wales using the links below: SSSI boundaries: Sites of Special Scientific Interest (SSSI) | DataMapWales (gov.wales) SSSI boundaries buffered to 300m WOM21 Site of Special Scientific Interest (SSSI) / Special Area of Conservation (SAC) 100/300m Buffer | DataMapWales (gov.wales) Priority Ecological Network in the marine environment At sea, an ecologically coherent network of marine protected areas (MPAs) has been established which, when measures are in place to bring about good condition, will form the marine Resilient Ecological Network. Connectivity within the MPA Network is inherently good, however some of the features (species and habitats for which the sites are designated) are known to be in unfavourable condition (Natural Resources Wales / Indicative feature condition assessments for European Marine Sites). The marine Priority Ecological Network (MPEN) map shows the full extent of the MPA network (light blue), highlighting the sites where one or more features are known to be in unfavourable condition (hatched area). In these hatched areas, action is needed to deliver measures that restore features, reduce pressures to enable their recovery, or gather evidence needed to support effective management. NRW continues to gather and assess information about the condition of habitats and species across the MPA network. Future iterations of the MPEN will incorporate new evidence and understanding as it becomes available. Alongside the MPEN it may be useful to view: Natural Resources Wales / Indicative feature condition assessments for European Marine Sites: reports of indicative features condition assessments, undertaken in 2018. Natural Resources Wales / LIFE N2K Thematic Action Plans: which contain information on key pressures and threats that affect sites and features within the MPEN. Other useful open datasets available for download from DataMapWales include: Marine Protected Areas in Welsh Waters | DataMapWales (gov.wales): the MPA network includes: Special Areas of Conservation; Special Protection Areas; Ramsar sites; Sites of Special Scientific Interest and a Marine Conservation Zone. Marine Special Areas of Conservation (SAC) Features | DataMapWales (gov.wales): indicative baseline extent and status of Special Areas of Conservation habitat features at the time of site designation.

Ecological connectivity is a key consideration in planning for effective biodiversity conservation and building ecosystem resilience through Resilient Ecological Networks (RENs). Modelled habitat networks can provide insights into how landscapes are likely to be functioning and inform the location of actions to improve the connectivity and resilience of protected sites. This spatial dataset consists of maps of habitat networks originally developed by Countryside Council for Wales (CCW) in collaboration with Forestry Commission Wales and Forest Research using a least-cost modelling approach, and now managed and progressively developed by Natural Resources Wales. Patches of habitat and other intervening habitats through which many of their species can move are mapped as habitat networks, which are available for habitats including native woodland, semi-natural grassland, heathland, bog, and fen. Results are available for the whole of Wales and include three levels of habitat networks; core networks (areas within which species that require extensive habitat and disperse poorly are able to move), focal networks (areas within which species tolerant of smaller habitat patches and with greater dispersal ability are able to move), and local networks (areas within species that can persist within small habitat patches and have very limited dispersal abilities can move). These habitat networks also form the basis of ‘Priority Ecological Networks’ (PENs), a subset of the ‘focal’ networks described above which have been selected against our suite of Protected Sites.
