What is Biodiversity Net Gain (BNG)?
Biodiversity Net Gain (BNG) aims to leave the natural environment in a measurably better state than before. Compulsory for most new developments, this approach encourages developers to enhance biodiversity through habitat creation and improvement, while also avoiding or mitigating potential harm. Collaboration with local stakeholders is key to supporting regional biodiversity goals and ensuring lasting environmental benefits.
How to Prove Biodiversity Net Gain (BNG) in Your Development
To prove BNG for your planning application, you must provide a comprehensive set of documents and calculations, including:
- A written assessment and maps showing your BNG, including the DEFRA Biodiversity Metric 2.0
- The required net gain level set by the local planning authority
- Strategies for achieving at least a 10% net gain on-site or alternative compensation options
- Financial provision for 30 years of biodiversity management (via a s106 agreement or similar)
- A Design & Access Statement outlining your BNG approach
- Evidence from an ecological consultant regarding mitigation and net gain assessment
Engaging with an ecological consultant early in the process is crucial. Our consultants will collaborate with landscape architects and urban designers to devise effective strategies to achieve BNG for your development.
How is Biodiversity Net Gain Calculated?
BNG is measured by comparing the biodiversity value of a site before and after development. This process takes into account habitat retention, creation, and loss. Your ecological consultant will:
- Survey the existing habitats and their condition
- Assess proposed ecological and landscape designs
- Calculate biodiversity units before and after development using the DEFRA Biodiversity Metric
- Determine the percentage of biodiversity gain or loss
Achieving Biodiversity Net Gain
Our team conducts assessments that consider habitat distinctiveness, condition, regional significance, and connectivity. Adhering to the latest guidelines and meeting local planning authority requirements is essential for success. Publicly accessible habitat enhancements are generally preferred, as private garden measures may not qualify.
