How the South Downs National Park Authority Can Support Local Planning Authorities with Biodiversity Net Gain (BNG)

Biodiversity Net Gain (BNG) is a critical element in ensuring that development projects contribute positively to the natural environment. With the implementation of the Environment Act 2021, BNG has become a mandatory consideration for many planning applications. For Local Planning

Authorities (LPAs), setting up the necessary frameworks, processes, and expertise to manage BNG can be a challenging endeavour. This is where the South Downs National Park Authority (SDNPA) can provide invaluable support.

Why BNG Matters

BNG requires that new developments leave biodiversity in a measurably better state than before. It is not just a compliance measure but an opportunity to create thriving natural spaces, enhance

ecosystems, and improve quality of life for communities. In the South Downs National Park, BNG aligns with our vision of protecting and enhancing the area’s unique natural beauty and biodiversity.

Challenges for Local Planning Authorities

Many LPAs face hurdles when implementing BNG, including:

Limited Resources: Establishing BNG processes requires expertise, funding, and time, which may strain existing LPA resources.
Complex Calculations: Accurately assessing biodiversity baselines and calculating net gain can be technically demanding.
Stakeholder Engagement: Developers, ecologists, and local communities need clear guidance and consistent communication.
Monitoring and Reporting: Ensuring compliance over the long term requires robust systems for tracking and reporting.

How SDNPA Can Help

The South Downs National Park Authority has extensive experience in delivering nature-based solutions and managing biodiversity projects. We can assist LPAs in the following ways:

1. Providing Expert Guidance

Our team of biodiversity specialists can help LPAs:

• Understand the regulatory requirements of BNG.

• Develop local policies and strategies to integrate BNG into the planning process.

• Deliver training sessions for planning officers and other stakeholders.

2. Creating Habitat Banks

SDNPA can educate on how LPAs can assist landowners in the establishment and successful

management of habitat banks, which are essential for developers needing off-site compensation

options. These habitat banks ensure high-quality, long-term biodiversity improvements within the region aligned to the Lawton Principles of nature restoration.

3. Developing Biodiversity Net Gain Tools

We offer tools and resources and support in how to use them to help LPAs:

Accurately calculate biodiversity baselines and net
Standardise assessments to ensure consistency and fairness across
Secure land use change through s106 templates
Calculate compliance monitoring fees
Set principles for nature restoration on habitat banks

4. Facilitating Partnerships

By fostering collaboration among developers, local authorities, conservation groups, and landowners, we can create coordinated approaches to BNG. This ensures that biodiversity improvements are strategically planned and deliver maximum impact to people and nature.

5. Monitoring and Compliance Support

SDNPA can assist in setting up monitoring frameworks to:

Track progress on biodiversity
Ensure long-term compliance with BNG
Provide transparent reporting for

Success Stories

In partnership with local councils and developers, SDNPA has successfully delivered biodiversity projects that serve as models for BNG implementation. For example:

Habitat restoration projects that have increased populations of rare
Collaborative initiatives with local communities to enhance green

Let’s Work Together

As the UK’s first National Park to integrate nature markets and biodiversity credits into its strategy, the South Downs National Park Authority is uniquely positioned to help LPAs achieve their BNG goals. Together, we can create a resilient natural environment that supports wildlife, enhances community well-being, and meets the demands of sustainable development.
