BNG
Biodiversity Net Gain (BNG) is a conservation approach within the UK, emphasising the importance of leaving the environment in a better state than before. BNG is essentially a principle to quantify and enhance the natural value of a site. It involves assessing the existing biodiversity, setting measurable targets, and implementing measures to improve the overall ecological value. The goal is to achieve a net gain in biodiversity, ensuring that any potential harm caused by development is offset by ecological enhancements.
Estrada Ecology has a wealth of experience in undertaking Biodiversity Net Gain, and can provide full surveys, reports, and consultation services to guide you through the process.
What Developers Need to Know
- BNG becomes a mandatory requirement in February 2024
- BNG requires a minimum 10% gain in biodiversity. Some local planning authorities may require a higher net gain
- Significant financial penalties are enforced if net gain isn’t achieved
- It is recommended to undertake BNG surveys during the growing season (April to September). If BNG surveys are undertaken outside of the growing season this will force classification of all landscapes to be ‘good’, leading to a higher baseline score and needing more ecological enhancement
- Clearance of land to avoid BNG will result in the local planning application requesting a retrospective baseline assessment being undertaken. This will likely result in higher cost implications
Key components of Biodiversity Net Gain include:
1. Baseline Assessment:
Conducting a thorough assessment of the existing biodiversity on the site to establish a baseline. This involves identifying habitats, species, size, and their ecological classification of impact. We advise, this should be undertaken during the growing season (April to September).
2. Setting Targets:
Establishing clear and achievable targets for biodiversity improvement. These targets are determined based on the specific characteristics of the site, its location, and the potential impacts of the development. This provide a clear outline for the size, number, and species that is required.
3. Ecological Enhancements:
Implementing measures outlined within the BNG report to enhance biodiversity, such as habitat creation, restoration, or improvement in the form of a Land Management Plan. This could involve planting native vegetation or installing features to support local flora.
4. Monitoring and Reporting:
Regularly monitoring the site's biodiversity to track progress toward the established targets. Reporting mechanisms ensure transparency and accountability, allowing stakeholders to assess the success of the Biodiversity Net Gain initiative. Monitoring schemes are in place over 30 years and are enforceable by local authorities to ensure that landscaping plans succeed.
5. Off-Site Contributions:
In some cases, where on-site improvements are not feasible, developers may contribute to off-site biodiversity projects to achieve the required net gain. This is the least favourable option for developers given the potential for high financial penalties.
