Restoration Activity Footprint This dataset shows the total area of peatland restoration across Wales up to present day. The data is presented as a polygon shapefile, with the unit of measurement being hectares. Restoration Activities This dataset shows the total area, measured in hectares, of peatland restoration that carried out across Wales up to the present date. The data is presented as a polygon shapefile that captures restoration activities. Restoration activities have been divided into five broad groups: Hydrological Management, Erosion Control, Tree Management, Vegetation Management and Grazing. Hydrological Management aims to reverse the impact of harmful activities that have resulted in adverse changes to hydrological regimes. Erosion Control aims to reduce the effect of erosional features such as haggs and gullies. These features expose areas of bare peat which are prone to further degradation if left uncontrolled. Tree Management aims to reduce the impact of trees on peatland. Most Tree Management techniques for peatland restoration involve conifer plantation, there are also activities addressing the presence of broadleaf trees. Vegetation Management aims to control the dominance of small numbers of abundant species (e.g. Molinia, Calluna) to ensure the recovery and persistence of mire vegetation. Grazing activities aim to restore and manage peatlands through modifying grazing regimes. The data is broken down into polygons with columns detailing the broad activity types, sites, delivery organisation, start and end dates of restoration activity, and the financial year it occurred in. Further information on the structure of the dataset can be found in the ‘Restoration Activity - Technical Metadata’.

This is a spatial dataset contain the location of Traditional Orchards sites around Wales. Traditional orchards are listed as a UK BAP priority habitats, which are those habitats that were identified as being the most threatened and requiring conservation action under the UK Biodiversity Action Plan (UK BAP). Traditional orchards are structurally and ecologically similar to wood-pasture and parkland, with open-grown trees set in herbaceous vegetation, but are generally distinguished from these priority habitat complexes by the following characteristics: the species composition of the trees, these being primarily in the family Rosaceae; the usually denser arrangement of the trees; the small scale of individual habitat patches; the wider dispersion and greater frequency of occurrence of habitat patches in the countryside. Traditional orchards include plantings for nuts, principally hazel nuts, but also walnuts.

A map of the land of Wales, graded to show levels of Tranquillity. It results from combining several underlying layers of data, covering different factors that either contribute to tranquillity or detract from tranquillity. Produced to provide a strategic baseline for monitoring change in tranquillity in Wales to inform strategic planning and policy-making. Tranquillity is an aspect of the Welsh Government’s Noise Action Plan (in response to the European Noise Directive) and is one of the qualitative measures of natural resources benefits provided by landscapes.

Designated sites in Wales include, but is not limited to, Sites of Special Scientific Interest (SSSI), Special Protection Areas (SPA), Special Areas of Conservation (SAC) and Ramsar sites. These sites have been divided into management units. This dataset contains the boundaries of these units and includes information such as designation type, unit name, unit area, national grid reference and former Countryside Council for Wales (CCW) regions. Digitising began in 2007 and is ongoing as and when new sites are created or existing sites are altered. The purpose of these management units is to have a coherent plan in order to manage sites in a practical manner to ensure that work is done to get sites and their corresponding features into a favourable condition, as per the requirements of the protected sites.

'Urban waste water' is defined in the Urban Waster Water Treatment Regulations (UWWTR) as the mixture of domestic waste water from kitchens, bathrooms and toilets, the waste water from industries discharging to sewers, and rainwater run-off from roads and other impermeable surfaces such as roofs, pavements and roads draining to sewers. Urban waste water is often referred to as ‘sewage’. The UWWTR is intended to protect the water environment for the animals and plants that live in and around water, as well as for recreational purposes and use as a resource for drinking water, sanitation, industry and commerce. This entry refers to a series of spatial datasets that can used in Urban Waste Water management. Under the UWWTR further sensitive areas have been identified because further treatment than secondary or equivalent treatment is necessary to meet other EC Directives such as the Water Framework Directive. Areas that come under as sensitive areas include Bathing Waters, Shellfish Waters and waters that are or soon to be Eutrophic. UWWTR Shellfish Waters shows only areas that are designated by Welsh Government under the Water Framework Directive Regulations. UWWTR Bathing Waters shows sites shows where treatment more stringent than secondary is necessary to fulfil the requirements of the Bathing Waters Directive and should be designated as sensitive areas by Defra UWWTR Eutrophic Waters are water bodies that are (or may soon become) eutrophic should be designated as sensitive areas by Defra. This applies to still fresh waters, rivers, estuaries and coastal waters. Attribution statement Contains Natural Resources Wales information © Natural Resources Wales and Database Right.

The primary aim of the project was to complete woodland community descriptions of all Sites of Special Scientific Interest (SSSls) in Wales that have semi-natural woodland as a qualifying feature. There was also a need for some survey of woodland on SSSls where woodland is not the outright qualifying feature and some areas of non-SSSI woodland (primarily pSSSI and areas of woodland adjacent to existing SSSls). This dataset contains detailed Phase 2 survey data from over 800 woodlands of conservation interest in Wales, predominantly SSSI and pSSSI woodlands. The purpose of this data capture was to improve the overall knowledge of Welsh woodland communities, to provide consistent community descriptions across the woodland SSSI series as fundamental site-support information and to assess SSSI status of new sites. Phase 2 woodland surveys have been carried out periodically since the late 1980s but a concentrated period of survey on SSSI and pSSSI woodland occurred from 1995 and 2000. Data was collected by trained personnel, digitised by contractors, validated by CCW Knowledge Management Group, corrections made by contractors, validated again by CCW Knowledge Management Group, corrections made in-house in conjunction with Woodland Ecologist. Standard woodland NVC survey methodology was used to collect this data. Woodland communities were identified by eye and mapped, supported by sample quadrats and target notes. Dataset is a collation of CCW commissioned NVC surveys. Attribution statementContains Natural Resources Wales information © Natural Resources Wales and Database Right. All rights Reserved.

National Vegetation Classification (NVC) is the basis used for the selection of Sites of Special Scientific Interest (SSSI) and is used to define Annex 1 habitats for the selection of Special Areas of Conservation (SAC) under the Habitats Directive (EU Directive 92/43). This project comprises of detailed data related to the Phase 2 plant community survey for Lowland Heath across Wales. The project covers dry and maritime heath covered by the heathland section of the NVC and wet heath covered by the section of the NVC. Two non-NVC communities the calcareous grass and heath, and shingle heath are also described. This project had three main purposes: - To provide an overview of the Welsh lowland heathland resource allowing local conservation programs particularly local Biodiversity Action Plans (BAP) partnerships, to assess and interpret their resource in a Welsh context. - To identify heathland types which are underrepresented in the SSSIs series. - To identified gaps in knowledge and highlight areas for further study. A total of 13 surveys were carried out: Anglesey (1994), West Gwynedd (1993), Gwynedd and Anglesey (1994), Pembrokeshire (1995, 1996, 1997), Rivers Ystwyth and Rheidiol, Ceredigion (1995), Gower Commons (1997), Gower, Bridgend, Vale of Glamorgan, Conwy (1998), Powys (1999), Brecknock and Carmarthenshire (2000), Ceredigion (2001) and Gower (2001). The total area of heath surveyed is approximately 4714 ha which is 35% of the total area of lowland and coastal (maritime) heathland recorded in the phase 1 habitats survey of Wales (1979- 1997). The age of the data is a limitation as habitat composition may change over time, a record of a vegetation type in the data is therefore no guarantee that it is still extant on the ground Vegetation mapping and community definition followed the National Vegetation Classification (NVC). The dataset has been extensively validated and verified however problems were encountered when mapping in field which may have resulted in errors, digitisation was of poor quality and there were occasional problems with identifying community type.

This dataset shows the boundaries and baseline classification, undertaken in 2021, for The Water Framework Directive (WFD) Cycle 3. It is an update in classification for all water bodies in Wales following on from the cycle 1 and cycle 2 classification rounds. The Water Environment (Water Framework Directive) (England & Wales) Regulations 2017 (referred to as the WFD Regulations) provide a framework for managing the water environment in England and Wales. The Directive aims for “good status” of all ground and surface water (rivers, lakes, transitional water, and coastal waters). Under the WFD Regulations, a river basin management plan must be prepared for each river basin district. The plan includes environmental objectives and a summary of the programmes of measures required to achieve those objectives. All waterbodies have been assessed and are included within the local River Basin Management Plan (RBMP). NRW updates the classification every 3 years. The Cycle 3 Interim classification will be available in 2024. It will be published in tabular format on Water Watch Wales. It can then be joined to the WFD water bodies, if required.

WFD Coastal Waterbodies is a spatial dataset containing attributes that have been collated as defined for the implementation of the Water Framework Directive (WFD). WFD Coastal Waterbodies 1st Cycle defining coastal waterbodies for the implementation of the Water Framework Directive (WFD). Article 2, clause 7 of the WFD defines coastal waterbodies as 'a surface water on the landward side of a line, every point of which is at a distance of one nautical mile on the seaward side from the nearest point of the baseline from which the breadth of territorial waters is measured, extending where appropriate up to the outer limit of transitional waters'. Coastal waters were defined by territorial waters 1 nautical mile from the Mean High Water, and the coastline taken directly from OS 1:50K MeridianTM 2. The break between coastal and estuarine waters was defined as transitional waterbodies. Since waterbodies are attributed with a unique identifier (EA_WB_ID) this dataset can be linked directly to other WFD data sources such as physical characteristics, risk, classification and proposed objectives.

Water Framework Directive (WFD) Groundwater bodies Cycle 1 is a spatial (polygon) dataset containing attributes that have been collated as defined for the implementation of the Water Framework Directive (WFD). Article 2, clause 2 of the WFD defines them as '...all water which is below the surface of the ground in the saturation zone and in direct contact with the ground or subsoil'. For the purposes of reporting under the WFD a groundwater body represent a distinct body of groundwater flow with a coherent flow unit including recharge and discharge areas with little flow across the boundaries. These reflect hydrogeological characteristics containing information on flow and stage properties, recharge and vulnerability to pollution. This has been undertaken through defining aquifers into different types and broken into catchment units at Catchment Abstraction Management Strategy (CAMS) scale. Since water bodies are attributed with a unique identifier (EA_WB_ID) this dataset can be linked directly to other WFD data sources such as physical characteristics, risk, classification and proposed objectives.

Water Framework Directive (WFD) River Basin Districts (RBD) is a spatial dataset containing attributes that have been collated as defined for the implementation of the Water Framework Directive (WFD). Article 2, clause 2 of the WFD defines them as '…the area of land and sea, made up of one or more neighbouring river basins together with their associated groundwaters and coastal waters…'. River Basin Districts have been delineated by using River Catchments as "building blocks" that have been aggregated together within a GIS, ensuring that WFD rivers do not intersect boundaries. Coastal and transitional waterbodies are also merged and assigned to a river basin district. River Catchments were delineated through use of flow data and a digital terrain model run through a hydrological model.

WFD River Waterbodies is a polyline Shapefile dataset collated as defined for the implementation of the Water Framework Directive (WFD). The river polylines were defined by using of the Environment Agency - General Quality Assessment (GQA) River Stretches dataset this is copied directly from the CEH 1:50K River Network with some additional stretches added in by the Environment Agency. Additional stretches were added to cover all stretches designated under the Fresh Water Fish Directive, all stretches designated within riverine SSSIs, and ensuring that all riverine abstractions which contributed to the designation of a Drinking Water Protected Area were sited on a designated river waterbody. In addition to this, some stretches were added where the upstream catchment size was > 10km2, but no other river stretch was designated (10km2 was the original cut-off catchment size form defining a waterbody under the WFD). The resultant WFD river waterbody datasets is a sub-set of the CEH network, including only stretches that meet any of the criteria outlined above. WFD River waterbodies share the same 'EA_WB_ID' as their river waterbody catchment allowing these 2 datasets to be linked. All river waterbodies are associated with a waterbody catchment. Not all catchments have a designated WFD river waterbody within them. These data apply to Cycle 1 of the Water Framework Directive. The equivalent layer for Cycle 2 is covered by WFD River Waterbodies Cycle 2. Attribution statement Contains Natural Resources Wales information © Natural Resources Wales and Database Right.

This is a spatial dataset identifying the river waterbodies managed under the Water Framework Directive and any related programs. 'WFD River Waterbodies Cycle 2' is a subset extracted from the NRWs Detailed River Network. Other input datasets and extensive local Natural Resources Wales staff knowledge has been used to augment the core geometry to incorporate critical spatial detail and attribution, such as flow direction and path, not available from the OS mapping and to verify the accuracy of the centreline itself. Sections of DRN belonging to a particular waterbody have been merged together so that a defined waterbody is a single record within the dataset (rather than being made up of hundreds of records within the DRN). DRN attributes become obsolete at this point and waterbody specific attribution has been added. Therefore the geometry for the resulting waterbodies is taken from the DRN, but the attribution and number of records is very different. Not all sections of the DRN belong to defined waterbodies and the final WFD river waterbody dataset represents <20% of the online DRN. Information Warning Anomalous results were observed at freshwater sampling points throughout Wales for orthophosphate between January 2014 and December 2016. This data was used as part of the 3-year data set which informed the 2015 WFD classification and affected the outcome of that exercise.

The 'WFD River Waterbody Catchments' are a polygon Shapefile dataset collated as defined for the implementation of the Water Framework Directive. Catchments are defined as an area of land from which all surface run-off flows through a series of streams, rivers and, possibly, lakes to a particular point in the water course such as a river confluence. Delineation of the river catchment boundaries primarily utilised the CEH Flow Grid hydrological model run with CEH Integrated Hydrological Digital Terrain Model (IHDTM) data so as to determine water drainage into river stretches. Upstream catchment size was calculated within an ESRI GIS environment using the extension Arc Hydro.
