This document is intended to provide a framework for writing reports for projects that are aiming to achieve Biodiversity Net Gain (BNG). BNG is a specific, measurable outcome of project activities that deliver demonstrable and quantifiable benefits to biodiversity compared to the baseline situation. In order to achieve BNG, a project must be able to demonstrate that it has followed all 10 of the Principles of Biodiversity Net Gain.

The templates provided in this document set out a suggested structure and content for reports specifically produced in relation to BNG assessments. The templates have been designed for development projects but can be adapted for other land use change projects and appraisals.
