Biodiversity Net Gain


Biodiversity net gain (BNG) is an approach introduced under the Environment Act 2021, to ensure that developments and land management leave the natural environment in a better state than it was before. It contributes towards nature recovery by helping to deliver habitat creation and enhancements as part of the design of new development.

Measurable BNG provides an opportunity to improve the connectivity of nature on a landscape scale, by promoting more, bigger, better, and joined up habitats. We need BNG because the State of Nature Report (2023) shows that the abundance of 753 terrestrial and freshwater species have declined by approximately 19% in the UK since 1970, and nearly 1 in 6 species (16%) are now threatened with extinction. A collective strategy is therefore necessary to restore and conserve biodiversity.

The information below sets out our response to some common issues and questions about Horsham District Council’s approach to BNG.
