Biodiversity Net Gain
Land management solutions that deliver for nature
Â
Biodiversity Net Gain (BNG) is a new approach to ensure future residential and commercial development contributes towards nature’s recovery. Developers must ensure the land they use is left in a better condition for wildlife than before work started. If it isn’t, new habitats must be created offsite.
In England, BNG became mandatory for all major developments from 12 February 2024 with regulation for small sites taking effect from 2 April 2024.
As part of the planning process and before a development begins, the biodiversity of the proposed site must be assessed and the impact of the development on it calculated, using the DEFRA metric*.
Planning applications which do not deliver a minimum 10% increase in biodiversity onsite will be rejected unless they are able to achieve this through the creation of new habitats offsite.
At BBOWT we have been working hard to ensure BNG truly delivers for nature, in addition to existing environmental protection in the planning system. The priority is always to avoid harming habitats.
The Environment Act says habitats created offsite need to be maintained for only 30 years. At BBOWT we believe they should be maintained and protected forever.
We want to see BNG regulation supporting nature’s recovery.
It cannot be just a compensation scheme for economic development, where the environment and local communities lose out.
We have over 60 years’ experience of creating, maintaining and protecting precious sites for nature, so we are perfectly placed to deliver BNG. Therefore, we have established our own habitat banks, using BNG to create amazing habitats which we can protect for generations to come.
BBOWT is offering an end-to-end service that begins prior to development, advising on ways to minimise environmental impacts on-site, through to creating off-site habitat banks. This will enable BBOWT to provide biodiversity credits to developers, to help support the creation or expansion of nature reserves and new places for wildlife.
Nature’s recovery is at the heart of our work, so we will only work on projects where we believe they will truly benefit nature.

BBOWT Habitat Banks
- BBOWT’s Habitat Banks provide offsite biodiversity units to Local Planning Authorities and developers who are looking to fulfil their BNG requirements and go above and beyond for nature.
- Our first habitat bank, Duxford, is located in Oxfordshire and was established with support from the Trust for Oxfordshire’s Environment in 2023.
- Duxford and our next habitat bank, Ludgershall in Buckinghamshire, will both be providing biodiversity credits to developers in 2024 through our management, restoration and enhancement of these natural habitats.
Our habitat banks are being designed and developed by our own team of ecologists and nature reserve managers, to create and enhance habitats and make new spaces for wildlife.
They are close to our existing nature reserves creating more connected landscapes across our nature recovery network.
Sites will be managed by BBOWT not just for the 30-year mandatory period, but forever, leaving a real legacy for wildlife.
All income generated from BNG will be fully reinvested into the development and management of habitat banks across the three counties, meaning all BNG sales will be truly supporting nature’s recovery.

* The DEFRA metric is a way of assigning a numerical value by way of habitat units to the biodiversity on a site. Post-development the site must have 10% more units than pre-development. If it does not, the developer needs to create those units offsite, purchase biodiversity units from a habitat bank or through the statutory credit scheme.
