Dudley Metropolitan Borough Council publishes guidance explaining how BNG affects developers and what information may be required with planning applications. The council also publishes a Biodiversity Net Gain Validation Requirements guidance note, which applicants should check when preparing a submission.
One important local consideration is strategic significance within the statutory biodiversity metric. This reflects the importance of a habitat’s location for nature recovery. Dudley Council’s published guidance directs applicants to use the West Midlands Local Nature Recovery Strategy resources alongside the relevant national guidance when calculating this element of the metric.
The council also explains the priority given to habitat retention, enhancement and creation within the development site, followed by appropriate off-site provision where necessary. Statutory biodiversity credits are a last resort under the hierarchy.
These considerations make it worthwhile to plan BNG alongside the proposed layout rather than treating it as a calculation to complete once the design is finalised. The requirements for an individual development will depend on the proposal, the site’s ecological characteristics and any applicable exemptions or transitional provisions.
We support projects across all Dudley neighbourhoods, including the town centre, Stourbridge, Sedgley, Kingswinford, Dudley Port, Brockmoor, and the surrounding borough areas.
A Biodiversity Net Gain Assessment establishes the biodiversity value of a site before development and considers how the proposed scheme could change that value. It uses habitat information and the applicable statutory biodiversity metric to calculate biodiversity units and compare the baseline with the proposed habitat outcomes.
A BNG Assessment can help establish:
Which habitats are present within the development boundary and their condition.
The site’s baseline biodiversity value.
How the proposed layout could affect existing habitats.
Opportunities to retain, enhance or create suitable habitats on-site.
Whether additional off-site biodiversity provision may need to be considered.
In Dudley, it is also important to understand whether local ecological designations, nature-recovery priorities or relevant planning requirements could affect the site. The council’s published BNG guidance refers to the West Midlands Local Nature Recovery Strategy when determining strategic significance in the biodiversity metric.
Starting the assessment early can help inform the layout and highlight where further ecological information may be required. The scope will depend on the site, the proposal and the information already available.
A BNG Assessment does not replace other ecological work. Separate protected species surveys, habitat assessments or other reports may still be required depending on the location and characteristics of the development.Â
Where statutory BNG applies, a Biodiversity Gain Plan explains how the development will deliver the required biodiversity gain. It is a separate stage from the initial assessment and must be approved by the relevant planning authority before development begins.
The plan brings together the relevant information about the proposed development, the biodiversity baseline and the approach to delivering the required gain. This includes the applicable metric calculations and details of the proposed habitat measures.
Depending on the project, these measures may include:
Retaining existing habitats and enhancing their condition.
Creating suitable new habitats within the development boundary.
Securing eligible off-site biodiversity units where on-site delivery is insufficient.
Using statutory biodiversity credits as a last resort, where permitted.Â
The strategy must be realistic for the site and follow the applicable biodiversity gain hierarchy. Significant on-site habitat gains and off-site gains can also carry long-term management and legal security requirements.
ProHort can help you understand how the Biodiversity Gain Plan relates to your BNG Assessment and what information may be needed as your project moves towards approval.
Dudley has a distinctive landscape shaped by its industrial heritage, varied geology, waterways, green spaces and designated nature-conservation sites. The borough forms part of the Black Country, where nature-recovery planning emphasises the importance of protecting valuable habitats and improving connections between green spaces.
Saltwells National Nature Reserve is one of the area’s notable nature-conservation locations. It illustrates the importance of protecting valuable existing habitats and considering how sites relate to the wider landscape.
For a development in Dudley, nearby nature-conservation sites may be relevant when reviewing potential ecological constraints and habitat connectivity. However, a site’s proximity to Saltwells or another designated area does not by itself determine its biodiversity value or establish that a particular restriction applies. The location, proposed works and potential effects need to be assessed individually.
Fens Pools is a Special Area of Conservation (SAC), making it an important example of why BNG should not be considered in isolation from other ecological and planning requirements.
BNG does not replace the protections that apply to designated nature-conservation sites, important habitats or protected species. Where a development could affect a designated site, separate consideration of the relevant planning and ecological requirements may be necessary.
A BNG Assessment helps establish the biodiversity value of the development site, but it is not a substitute for any additional assessment needed to understand potential impacts on a designated site.Â
Waterways and linear green corridors can be important for wildlife movement through the wider Black Country landscape. Dudley’s planning evidence includes consideration of the River Stour and its tributaries, while local nature-recovery work also recognises the value of connecting habitats through rivers, canals and other green corridors.
Where a development contains a watercourse, lies alongside a canal or includes connected vegetation, the existing habitats and possible impacts should be considered during the assessment. Suitable retention or enhancement may help inform the proposed biodiversity strategy, subject to the applicable metric rules and site-specific evidence.
Dudley’s industrial history means development proposals can involve previously used land, established built-up areas and sites with a mix of hardstanding and vegetation. The previous use of a site does not automatically mean it has no biodiversity value.
Grassland, scrub, trees and other habitats can establish on previously developed land, and their value depends on what is present and its condition. Assessing these features before the design is fixed can help identify opportunities to avoid unnecessary habitat loss and consider suitable habitat creation or enhancement.
The most appropriate BNG strategy depends on the site’s baseline, the development layout and the habitats that can realistically be retained, enhanced or created.
The biodiversity gain hierarchy should guide the process. Impacts on habitats should first be avoided, then minimised, before considering appropriate compensation and other ways of delivering the required gain.
On-site delivery may be possible where the site has suitable space and conditions for habitat retention, enhancement or creation. General landscaping alone does not automatically provide statutory biodiversity units: proposed habitats must be suitable under the applicable metric and their contribution depends on factors such as habitat type, condition and location.
Where the required gain cannot be delivered entirely on-site, eligible off-site biodiversity units may be an option. Their suitability and availability should be checked against the project’s specific requirements. Any proposed gains must be secured and managed in accordance with the applicable rules.Â
Provide the site address, boundary plan, proposed layout and any existing ecological reports. This helps establish the likely scope of the assessment and identify information that may be missing.Â
The habitats within the site are assessed and their biodiversity value calculated using the applicable metric. Relevant ecological evidence and location information help support the assessment.Â
The proposed development is reviewed against the baseline to identify potential habitat losses and opportunities for retention, enhancement or creation.
The proposed strategy considers the biodiversity gain hierarchy, suitable on-site measures and whether eligible off-site provision may be needed. Relevant local nature-recovery information should be considered when applying the metric.Â
Where statutory BNG applies, the plan explains how the required gain will be delivered and must be approved by the relevant planning authority before development commences.

Dudley Council publishes a Biodiversity Net Gain Validation Requirements guidance note setting out information it requests in addition to the applicable statutory submission requirements. Applicants should check the latest council guidance before submitting an application, as the information needed depends on the proposal and its circumstances.
Dudley Council’s published guidance directs applicants to use the West Midlands Local Nature Recovery Strategy resources when calculating strategic significance in the biodiversity metric. This element considers the importance of a habitat’s location for nature recovery. The relevant mapping and national metric guidance should be checked for the individual site.
Potentially. Fens Pools is a Special Area of Conservation, and designated sites have protections that are separate from statutory BNG. Depending on the development’s location and potential effects, additional ecological assessment or planning considerations may be required. A BNG Assessment alone does not establish that impacts on a designated site are acceptable.
It can, depending on the habitats present and their condition. Previously developed land may contain scrub, grassland, trees or other habitats that contribute to the baseline biodiversity value. A site-specific assessment is needed rather than assuming that former industrial use means the site has little or no biodiversity value.
Yes, where relevant habitats occur within the development site or may be affected by the proposal. Watercourses and connected habitats can be important for wildlife movement, and suitable habitat retention or enhancement may inform the strategy. The metric can only account for habitats and measures that meet its rules and are supported by appropriate evidence.
The council’s published guidance prioritises habitat enhancement and creation within the development boundary, followed by appropriate off-site habitat provision where needed. Statutory biodiversity credits are a last resort. The appropriate approach depends on the site’s characteristics, the development and the applicable requirements.
Significant on-site habitat gains and off-site habitat gains are generally subject to long-term security and management requirements, with statutory arrangements typically requiring at least 30 years. The exact mechanism and obligations depend on the type of gain and the applicable legal arrangements.
It is advisable to consider BNG at the site-selection and early design stages, before the layout is finalised. Early assessment can help establish the baseline, identify habitat constraints and explore opportunities for on-site delivery. It can also help you identify the information needed for a planning submission and the later Biodiversity Gain Plan, where required.
