The flood risk forecast is produced by the Flood Forecasting Centre (FFC) on a daily basis. It is issued more frequently when serious flooding is forecast. It provides the indication of the potential for flooding for five days: the day on which it is issued and the subsequent four days ahead.

The forecast highlights flood risk on a county by county basis and includes a short commentary on the situation. It covers flooding from rivers, the sea, surface water and groundwater for Wales and England.

This dataset is produced in partnership with the Met Office Flood Forecasting Centre and the Environment Agency and is intended to complement the Flood Warning Service provided by Natural Resources Wales.

This dataset shows management coupes. These are areas of intended management and may not be implemented when indicated or at all. The feature description field indicates the probable silvicultural system in use and the year field when that action will take place or be completed by. A related layer is restocking coupes which show what happens to the area after management has taken place

Water quality data is held in the WISKI Kisters Water Quality Module (KiWQM). The Water Quality Archive provides a central repository for all data relating to water quality measurements that have since the 1960's been collected from over 22,000 sampling points, with 2,500 active today. Samples are taken from coastal or estuarine waters, rivers, lakes, ponds, canals or groundwater. Additional data has been provided by third parties as public record. The data measures a wide range of water quality parameters, such as nutrients, metals and physio-chemical determinants for both archived and processed data and these are used to assess discharge monitoring against discharge permits, investigation of pollution incidents or environmental monitoring. Whilst this data is used to meet the requirements of The Water Framework Directive and Bathing Water Quality assessments, the system is currently unable to record anything about compliance.

This dataset contains details pollution incidents reported to Natural Resources Wales (NRW). Only substantiated and closed environmental protection incidents are included. Where these data indicate an incident occurred on a particular site or property no inference should be drawn that the site or property owner necessarily was responsible.

The Management Layer is the actual area of land NRW manages, this can be larger than the legal boundary, this is because we manage land that is not our own such as extra land or Partnership land.

Natural Resources Wales (NRW) species data held on the National Biodiversity Network (NBN) Atlas. 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 data portal is the main route for the publishing NRW species data. Details of each NRW species data can be viewed through the NBN Atlas.

The Emissions Inventory (EI) dataset collects data from regulated industrial activities and includes annual emissions to air and controlled waters, off-site transfers of waste and transfers of pollutants to wastewater.

The NRW EI includes all of the data from Wales that is published on the UK Pollutant Release and Transfer Register (UK PRTR) but also includes further emissions that are under the UK PRTR threshold.

The published dataset has been redacted to not include confidential permits.

This dataset covers monitoring data that is updated on our systems on a minimum of a daily update cycle. This is increased during times of flooding etc. Measurements of the height (m) of water in a river, lake or coastal site taken using automatic field devices, are given usually every 15 minutes. Information is available for NRW river monitoring sites throughout Wales, as well as some reservoirs and coastal sites.

Water temperature data is collected for different reasons and in different locations. Time series of surface water temperatures can provide indicators of climate change and associated ecological responses. An archive was created in 2007 as part of a research project, and is a unique collation of Natural Resource Wales and The Environment Agencies water temperature data from more than 30,000 sites across England & Wales. The archive contains water temperature data (up to 2007) and site metadata. The archive contains water temperature data (up to 2007) and site metadata. Most sites have records starting from the 1980s.

Some of Natural Resources Wales (NRW) core ecology datasets are held in the WISKI Kisters Ecology (KiEco). KiEco provides a central repository for some of NRW's ecological monitoring data. The database holdings include data on fish species, River Habitat Surveys, invasive species, marine benthic species and habitat monitoring, and freshwater ecology. KiEco was developed in NRW to take over the required functions of the legacy Environment Agency Wales (EAW) databases, such as Biosys National Fish Population Database (NFPD) and Ecosys.

This spatial Flood Warning Areas dataset are geographical areas where NRW expect flooding to occur and where NRW provide a Flood Warning Service.

Flood Warning Areas generally contain properties that are expected to flood from rivers or the sea. Specifically, Flood Warning Areas define locations within the Flood Warning Service Limit that represent a discrete community at risk of flooding. A discrete community is a recognised and named geographical community, which can be an urban area, a significant suburb of a large city or a village or a hamlet.

The purpose of Flood Warnings is to alert people that flooding is expected and they should take action to protect themselves and their property. An online viewable version of this dataset is available here https://naturalresources.wales/our-evidence-and-reports/maps/flood-risk-map/?lang=en

This dataset is made up of separate spatial layers from all three legacy bodies, Countryside Council for Wales (CCW), Environment Agency Wales (EAW) and Forestry Commissions Wales (FCW), all of whom now make up Natural Resources Wales (NRW). Dataset contains only polygons and includes information on site name, scale captured, unique codes. This provides accurate legal maps for management agreements, and provides a complete table showing all land owned by NRW in Wales. The purpose of this data capture was to provide an accurate digital legal maps for management agreements and provide a complete compilation of land owned or managed by NRW.

Natural Resources Wales is legally required to monitor all movements of hazardous waste in Wales. Hazardous waste producers are required to register with us and the site where the waste is disposed or recovered is required to inform us of the details of the wastes they receive. Hazardous waste producer data is commercially confidential. However a summary of the movements is provided in this Hazardous Waste Interrogator. Only high-level waste classification geographical locations (where the waste was produced and where the waste management facility is located) and tonnage is included. Individual site names and producers details are not included.

Natural Resources Wales (NRW) currently holds and collates current and former Countryside Council for Wales (CCW) marine benthic species, biotope, habitat, and particle size analyses data in Marine Recorder. A snapshot of the data may be made available through the use of the Marine Wizard and is also available on the NBN Gateway. NRW data are merged with snapshots of datasets from across Wales supplied from other data providers (e.g. JNCC, NE, DASSH and Seasearch) using the suite of tools provided with the program and made available for internal use. The purpose of marine data capture through the use of Marine Recorder is to provide access to all marine benthic species and habitats data at NRW through one program.

From 2024, the data will be migrated to the new Marine Recorder Online tool. A subset of data that is suitable for public use is published through the NBN Atlas.

This is a spatial dataset containing the extent polygons for the Natural Resources Wales Operational Areas.

This dataset shows the six main operational areas:
- North East Wales - North West Wales - Mid Wales - South East Wales - South West Wales - South Wales Central

These are also known as the same areas used for Area Statements.

It is the post OD (Organisational Design) catchment boundaries for the six NRW Operational Areas (or places).

This is a catalogue of images sourced from both slides and digital images. Approximately 75 percent are CCW, 10 percent are Head of the Marine and Freshwater Ecosystems Group or Freshwater Ecosystems Team Leader within NRW. Approximately 15 percent of the images are sources externally from volunteers or organisation - information about this is held within an excel document within the image catalogue. These images were captured for numerous purposes including, training, interpretation, monitoring, and stock images for publication.

This dataset contains daily rainfall totals, given in mm to 1 decimal place, for all rainfall stations included within this dataset. The list of stations to be defined by the file contents with no separate index of stations. The period for counting rainfall will be in line with the water day which is 24 hour period between 9am and 9am. Stations which do not meet quality control specification, eg missing or invalid data, will be omitted from the published file.

Within each Operational Area, Woodland is initially divided into Forest blocks, these are usually a specific number per woodland blocks. Sometimes very large areas of woodland are broken down into several blocks for management purposes. These geographic blocks are used to identify distinct groups of woodland within an operational area. Planning Staff use this block information to produce production forecasts at block Level. In 2004 Blocks were renamed Design Plan Units, but Blocks numbers are still used in Forester.

This dataset contains gas pipelines on NRW land. The data currently covers forestry areas but in future will expand to cover all operational areas. The data is collected locally by NRW operational staff to supplement any utility data available to NRW. The data is used in operational work using the Contract Mapper Module to ensure that when operational work is carried out by contractors they are aware of any locally captured overhead telephone line information.

This dataset comprises of boundaries for the 48 regional landscape character areas for Wales. The purpose of this data capture was to geographically distinguish different regions in Wales in terms of landscape identity and what characteristics and qualities make one region different and distinct from another.

These distinctions and policy drivers for this project are described, together with an illustrated narrative, and published on Natural Resources Wales (NRW's) website. This dataset covers 100% of terrestrial Wales including inter-tidal areas. Boundary data derived from source data 2007-2008 with the final version being amended October 2008. Some area names were amended in August 2023 to match written profile documents, and to reflect official status change for the names Eryri and Bannau Brycheiniog.
