Border Notifications

The Border Notifications (BN) dashboard is primarily an IT tool designed to exchange information between the Food Standards Agency (FSA) and Port Health Authorities (PHAs) in England and Wales on health risks related to imported food and feed. The BN system underpins the exchange of information to PHAs on food and feed related risks. This tool enables PHAs to take coordinated, coherent, and simultaneous actions to ensure the highest possible level of consumer protection. A BN is triggered by a PHA on the BN dashboard module when the existence of a serious, direct, or indirect, risk to public health linked to imported food or feed is detected.

Statutory Main River Map Variations

The Statutory Main River Map Variations dataset defines proposed changes to the Statutory Main River Map.

Statutory Main Rivers Map defines statutory watercourses in England designated as Main Rivers by Environment Agency.
 
Watercourses designated as ‘main river’ are generally the larger arterial watercourses.  The Environment Agency has permissive powers, but not a duty, to carry out maintenance, improvement or construction work on designated main rivers.

All other open water courses in England are determined by statute as an ‘ordinary watercourse’. On these watercourses the Lead Local flood Authority or, if within an Internal Drainage District, the Internal Drainage Board have similar permissive powers to maintain and improve.

The Environment Agency notifies the public and interested parties of our intentions to make a change to the statutory main river map and decides which watercourses are designated as Main Rivers following a legal process to determine and publish changes.

The change, or variation, to the Statutory Main River Map is either a deletion (also known as a demainment) or an addition (also known as an enmainment).

There are two reasons for a change to the Statutory Main River Map - Designation and Factual.

Designation changes are required when we make a decision to lengthen or shorten the section of a river designated as a 'main river'. These changes will determine which risk management authority may carry out maintenance, improvement or construction work on the watercourse. These changes result also in differing legislation applying to the riparian owner and others with an interest. 
 
Factual changes may be required to update the map to represent the real position of the watercourse. They do not involve any changes of authority or management. Typical examples of factual changes are when: a watercourse has changed course naturally, a watercourse has been diverted or a survey of a culvert shows a different alignment. 

A change to the Statutory Main River Map goes through the following stages (identified as Status within the data):

- Draft
- Consultation
- Pending Determination
- Determination
- Appeals
- Pending Appeals
- Pending Implementation

Flood Map for Planning (Rivers and Sea) - Water Storage Areas

The Flood Map for Planning (Rivers and Sea) includes several layers of information.  This dataset covers Water Storage Areas.  It shows those areas that act as a balancing reservoir, storage basin or balancing pond. Their purpose is to attenuate an incoming flood peak to a flow level that can be accepted by the downstream channel. It may also delay the timing of a flood peak so that its volume is discharged over a longer time interval. 
We have assumed that water storage areas act perfectly and give the same level of protection as when our assessment of the area was carried out. Water storage areas do not completely remove the chance of flooding and can be overtopped or fail in extreme weather conditions.

This dataset is designed to raise awareness of the likelihood of flooding and to encourage people living and working in areas prone to flooding to find out more and take appropriate action. Attribution statement: © Environment Agency copyright and/or database right 2025. All rights reserved.

Eryri Montane Lake Bryophyte Survey 2024

Rocks along the shores of montane lakes in Eryri have been found to be an important bryophyte habitat, supporting a range of rare and threatened bryophytes that grow only in this habitat.

Due to the limited niche of the species of this habitat, and in some cases very small populations, they are especially vulnerable to disturbance and a single disturbance event could lead to irreparable damage to or even loss of the Welsh population of some species. Therefore, it is of high importance to fully document the bryophyte flora of the shores of these montane lakes and identify rocks that support rare and important bryophytes and are vulnerable to disturbance. 

Seven montane lakes within the Eryri SSSI were surveyed in September 2024, spread between the three main massifs of Yr Wyddfa, Glyderau and Carneddau. 

Lakes were prioritised for survey based on the quality and quantity of recent bryophyte records. The full shore of each lake was walked and the locations of any rare or otherwise notable bryophytes encountered were recorded. 

Important boulders were identified and documented, with any damage present noted. A full species list was recorded from the shore of each lake.

KiEco Marine Benthic Invertebrates - Geospatial

This data collates all the benthic invertebrate samples collected within Wales from 1988 onwards by Natural Resources Wales and former Environment Agency Wales under the Water Framework Directive (WFD) and Clean Seas Environment Monitoring Program (CSEMP) sampling programs. The dataset contains the presence, and abundance, of benthic invertebrate species at specific marine monitoring points held within the KiECO database.

The data was collected using either a  Day Grab (0.1 m2) or Hammon Grab (0.1m2) for subtidal samples and either 3 x 0.01m2 cores (Core Diameter 11.28cm) or a Box Corer (0.1m2) for intertidal surveys. Data are laboratory assessed and quality assured following the National Marine Biological Analytical Quality Control (NMBAQC) scheme.

For many of our marine survey techniques we record an NGR at the site because this acts as a central/representative location around which we collect lots of samples. An NGR is then also recorded against each of the samples to give a more accurate sampling location

Monitoring of the Atlantic woodland bryophyte assemblage of Coed Crafnant, Meirionnydd

Coed Crafnant is a nature reserve owned and managed by the North Wales Wildlife Trust, comprising part of that woodland plus the contiguous Coed Dolbebin. Almost all of the oceanic woodland habitat of the reserve is contained within Rhinog SSSI and Meirionnydd Oakwoods SAC. 

The first comprehensive bryophyte survey of the reserve was undertaken during January 2014, when baseline monitoring data was collected. A further survey was undertaken in May 2022, which recorded areas of the reserve not covered in 2014, but did not repeat the species grid-mapping exercise of 2014 due to time constraints. This 2025 study aimed to repeat the grid-mapping in order to assess what changes have occurred within the Atlantic woodland bryophyte assemblage.

The potential reintroduction of Dicranum Undulatum to Cors Fochno: an assessment of future climate suitability

Dicranum undulatum is categorised as ‘Endangered’ on the Red Data List for Wales, and is considered to be of principal importance for conservation under Section 7 of The Environment (Wales) Act 2016. Due to the widespread loss and degradation of peatlands, it has undergone a large decline in Britain, and the only surviving population in Wales occurs in Denbighshire, on Whixall and Bettisfield Mosses. The species was known from Cors Fochno, where it was last seen in 1967. Reasons for the extinction are uncertain, but former fires may be partly to blame. Following significant efforts to improve the habitat condition of the bog, including the elimination of fires and large-scale hydrological restoration, a recent assessment concluded that parts of the site appear to contain favourable habitat for D. undulatum and that reintroduction may be a possibility. The aim of this study is to investigate whether a suitable macroclimate for the species is likely to occur at Cors Fochno in the medium-term.

Gweunydd Nant y Twyn SSSI - National Vegetation Classification (NVC) Grassland Survey (2024)

A standard Phase 2 NVC survey was undertaken at Gweunydd Nant y Twyn as part of the Site of Special Scientific Interest (SSSI) designation process.

Gweunydd Nant y Twyn consists of a cluster of small fields, with tall, wooded hedgerows. The site is of particular importance for bryophytes.

The site comprises the original Phase 2 site survey site of Mockridge et al. 1998, which has now been resurveyed (2024) and extended to include several contiguous small fields, and a further extension centred on 5 small nearby fields, approximately 1/3rd of a km to the north, linked by a block of woodland and pasture. The total area of the Phase 2 survey site is now 39.9ha.

Gwent Levels - Resilient Ecological Networks

Resilient Ecological Networks (RENs), are networks of habitat linking protected sites and other biodiversity hotspots across the wider landscape, providing maximum benefit for biodiversity and human well-being.  Such networks have existing or potential for healthy resilient ecosystems, which provide a range of important ecosystem services, as well as allowing the movement of species across landscapes in response to climate change and disruptive or adverse events. The maintenance, enhancement and re-creation of RENs are vital for nature recovery.

RENs are composed of Core Zones (including protected sites such as SSSIs) and Nature Recovery Zones. These mapped together form an applied opportunity map for a Network.

The current layers available are the mapped products of the Gwent Levels Nature Network, which define resilient ecological networks in this area: Core and Nature Recovery Zone.

As well as this set of priority networks, it is useful to also be able to view these layers alongside other open datasets available which are the:
- Sites of Special Scientific Interest NRW_DS98776
- Priority Ecological Networks NRW_DS125572

The output of the project has identified 42 core zones covering 18,979 hectares (ha) and 86 nature recovery zones covering 2,214 ha as two GIS layers. These broadly comprise freshwater, fen, bog, semi-natural grassland, and native woodland ecosystems. The Core Zone layer is based on sites designated for nature conservation in Wales (SAC, SSSI, NNRs, SINC, Priority habitats as identified in Section 7 of the Environment (Wales) Act, and Ancient Woodland database).


These layers highlight areas of opportunity and serve as an evidence base to support action planning, while remaining flexible and not prescriptive in terms of specific conservation measures.

Compliance Assessment of Welsh River Special Areas of Conservation (SACs) Against Water Quality Targets (2020 - 2023)

These data identify the compliance of Welsh river Special Areas of Conservation (SACs) regarding targets for eight water quality attributes: Phosphorus, Dissolved Oxygen, Biochemical Oxygen Demand, Total Ammonia, Unionised Ammonia, Trophic Diatom Index, pH and Acid Neutralising Capacity. 

The targets and methods of assessment are set at a UK level by the Joint Nature Conservation Committee as published in the Common Standards Guidance for Rivers 2016, and form part of the conservation objectives for the riverine SAC features. 

There are nine SACs in Wales with riverine features (known in their respective Core Management Plans as): 

• River Dee and Bala Lake 
• Afon Gwyrfai a Llyn Cwellyn 
• Coedydd Derw a Safleoedd Ystlumod Meirion (Afon Glaslyn) 
• Afon Eden - Cors Goch Trawsfynydd 
• Afon Teifi 
• Afonydd Cleddau 
• Afon Tywi 
• River Usk 
• River Wye 

For the purposes of water quality reporting, Natural Resources Wales (NRW) divides rivers into units called water bodies. A total of 119 (of a possible 127) water bodies, each with a single sampling point, were assessed for one or more attribute. The River Dee and Wye were assessed in the Welsh part of the SAC only. 

Water quality data collected by NRW’s routine surveillance monitoring programme for a four-year period (1st January 2020 – 31st December 2023) were extracted from the NRW water quality database (KiWQM) to assess compliance with targets. 

Data was not available for all attributes for all water bodies due to the risk-based design of NRW’s monitoring programmes. For attributes/waterbodies with insufficient data to determine compliance over the period 2020-2023, but where a result was produced in the previous assessment (using 2017-2019 data), the previous result has been rolled forward.

River Habitat Survey (RHS) and Plant Community survey data of the River Wye SAC 2024

In 2024, a River Habitat Survey (RHS), Simplified Phase 1 survey and LEAFPAC aquatic macrophyte survey was carried out on the River Wye Special Area of Conservation (SAC). This was to contribute to the condition assessment of features in the River Wye SAC as well as provide information to support the management and restoration of protected sites and the delivery of River Basin Management Plans. 

Twenty-two monitoring sites out of thirty-five possible sites were surveyed in the River Wye catchment between 5th August and 28th September 2024. 

At each site the following surveys were conducted: 
•	River Habitat Surveys (RHS), to assess the quality of physical habitat, supported by 
•	Simplified Phase 1 survey, and
•	Aquatic plant surveys using the rivers LEAFPACS method, along with 
•	Field observations of habitat quality to assist with interpretation of the data.

The principal outputs of this project are digital copies of field records including photographs, access and parking, along with a description of each site.

These surveys were conducted on the Welsh section of the River Wye SAC.

Llyn Horse Mussel Multibeam Echosounder Survey data 2024

This data is from the 2024 Llyn Horse Mussel (Modiolus modiolus) Multibeam Echosounder Survey (MBES). 

The work was carried out by Binnies/Hydrofix funded by Nature Networks as part of an investigation into the decline observed at the reef. Both reefs were mapped to International Hydrographic order (IHO) 1a or higher. 

The data was processed and analysed to produce bathymetric surfaces; backscatter mosaics; a seabed classification, including the extents of the mussel beds; and measurements of the mussel bioherms.  The results from the 2024 survey were then compared to previous datasets, provided by NRW, from 2005, 2008 and 2015, all of which were analysed and reprocessed.

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.
