Biodiversity net gain

Biodiversity net gain (BNG) is a development approach that seeks to enhance the biodiversity of a site over a fixed period of time, ultimately resulting in a higher biodiversity value than prior to the development. The biodiversity value of a site is measured prior to development to establish the baseline. This involves an assessment of the types of habitat present such as grassland, woodland, heathland or hedgerow, and a condition assessment to establish the quality of the habitats present. A second biodiversity assessment of the post-development site design and landscaping proposals is then carried out to establish the biodiversity unit value of the completed development, using the same criteria as the baseline assessment. The aim of BNG is for the post-development biodiversity value to be higher than the baseline. BNG aims to halt the national net loss of biodiversity, to reverse the decline and to support the delivery of better quality, better connected ecological networks.
