Biodiversity Net Gain

Biodiversity Net Gain leaves biodiversity in a better state than it was before development. This means that developers create more habitats or enhance existing habitat during development and attempts to limit damage to existing habitat as much as possible. Alongside our mitigation plans we also provide enhancement strategies to our clients, tailoring these plans to fit the existing ecosystems. We aim to enhance the effectiveness of the present habitat for the flora and fauna on the development and within the area. These plans can also provide aesthetic ‘kerb’ appeal and by doing so add value to a development project.

Biodiversity net gain can be done in a number of ways;

  • Avoid a site or areas within a site through good design, in favour of areas less rich in biodiversity,

  • Minimize the impact of the development on the site through good design, enhancements and mitigation

  • Remediate by restoring damaged or lost habitat on site

  • Compensate for unavoidable habitat loss by the creation of habitat off-site.


In December 2018 The Department for Environment, Food and Rural Affairs (DEFRA) announced a consultation to make it mandatory for all new developments to deliver a ‘Net Gain’ to biodiversity.

What impact does it have on the environment?

Despite conservation efforts biodiversity in the UK is declining, Natural Ecosystem Assessment (NEA) states that 40% of our most important habitats and 30% of our rarest species are declining. Biodiversity net gain helps to boost populations of threatened species and enhance natural connection.
