Biodiversity Net Gain: Enhancing the Natural Environment
Biodiversity net gain (BNG) is a vital approach to development and land management that focuses on improving the natural environment. It aims to create measurable improvements in biodiversity by enhancing or creating habitats associated with development. By implementing BNG, we can ensure that our actions leave the environment in a better state than before, promoting the variety of all living organisms and their habitats.
BNG can be achieved through on-site measures, off-site measures, or a combination of both. On-site measures involve strategies such as creating wildlife-friendly areas, planting native vegetation, or incorporating green roofs into buildings. Off-site measures may include the restoration of nearby degraded habitats or the creation of new habitats in other locations. By implementing BNG, we can enhance ecological receptors and habitat areas, contributing to nature recovery and sustainable development.
The importance of BNG lies in addressing the decline in wildlife abundance and biodiversity. The State of Nature report in 2019 revealed a significant decrease in the average abundance of wildlife in the UK since the 1970s. BNG provides additional protection and enhancement of habitats, going beyond existing species protections. It also contributes to addressing the climate emergency, improving green infrastructure, enhancing access to nature, promoting mental and physical well-being, and improving air and water quality. BNG recognizes the importance of nature for ecosystem services and the overall sustainability of the environment.
The Benefits of Biodiversity Net Gain:
- Enhanced ecological receptors (animals, insects, plants, fungi)
- Improved habitat areas
- Nature recovery and conservation
- Promotion of ecosystem services
- Climate change mitigation and adaptation
- Improved green infrastructure
- Positive impacts on mental and physical well-being
