Biodiversity Net Gain Assessments
The Inspired Ecology team are trained in calculating biodiversity units and achieving net gain in development projects.
The concept of Biodiversity Net Gain means that developments should result in an overall improvement in biodiversity for a site. At present, the revised National Planning Policy Framework (2019) states that Local Planning Authorities (LPAs) should “identify and pursue opportunities for securing measurable net gains for biodiversity“.
The new Environment Bill will firm up the requirement for Biodiversity Net Gain within all developments. Once the Bill becomes law, all developments will be required to include 10% Biodiversity Net Gain within their proposals. The 10% gain is a minimum requirement, with some LPAs requiring a larger gain in their region. This enhancement to biodiversity must also be managed and maintained for at least 30 years after the development is completed. Many LPAs are already beginning to request Biodiversity Net Gain assessments, alongside the usual ecological survey reports.
Biodiversity on a site can be measured using the Biodiversity Metric Calculation Tool. This tool uses information such as habitat types, habitat areas and habitat condition to create a measure of biodiversity for any given site. This allows the quantification of biodiversity, so that the required percentage gain can be calculated.
The calculation of biodiversity units must be made on both the baseline habitats on site prior to development and on the habitats available within the development proposals. Assessment of the habitats already present on site will require a site survey by an ecologist and the methods for achieving net gain within the development must be included within the project’s proposals. That’s why it is best to involve ecologists early in the development process, so that any necessary changes to habitats and site layouts can be made during the design phase of a project to avoid additional costs down the line.

Inspired Ecology are trained in using the Biodiversity Metric to calculate both the baseline and proposed biodiversity units for sites. The team are also able to provide advice on how Biodiversity Net Gain can be achieved on development sites, when initial proposals do not fulfil the minimum requirements.
