Biodiversity Net Gain Through Development


This course provides training on designing biodiversity net gain for development projects. It is based on the UK's good practice principles for biodiversity net gain (CIEEM/IEMA/CIRIA, 2016) and the associated practical guidance (CIEEM/IEMA/CIRIA, 2019). Please see links at the bottom of 'Description' to download the above mentioned documents.


The course is for individuals wishing to advance their skills in biodiversity net gain. Through presentations, case studies and practicals, the course focuses on implementing biodiversity net gain (BNG) for various types, sizes and locations of development projects including small-scale to large-scale, as well as rural and urban locations. It covers BNG during ecological impact assessments (including combining qualitative and quantitative assessments) and the following project lifecycle stages:

• Feasibility and scoping: including early consideration of BNG through the mitigation hierarchy and integrating BNG within core project documents.
• Designing BNG: including habitat trading, ecological equivalency, promoting connecting, achieving additionality, offsetting losses with gains elsewhere as the final stage of the mitigation hierarchy, and designing for a BNG legacy both on-site and off-site.

The course also covers planning for key requirements to deliver BNG during construction, and good practice to evidence BNG.

Please note: The trainers are reviewing this course for 2020 and as such there will be some amendments to the course Description and Learning Outcomes. These will be updated as soon as possible but the main learning from the course will not be significantly changed.

Please note that the course does not cover biodiversity unit calculations (or use of other biodiversity metrics) and that participants should have a minimum of a basic knowledge level of biodiversity metrics to attend this course.

To download the guidance, please us the following links:

- Biodiversity Net Gain. Good practice principles for development. (CIEEM/IEMA/CIRIA, 2016).

- Biodiversity Net Gain. Good practice principles for development. A practical guide. (CIEEM/IEMA/CIRIA, 2019).

Who Should Attend?

Primarily, ecological consultants who will be designing biodiversity net gain schemes and overseeing delivery of these schemes during the construction phase. Other target participants include: EIA coordinators; local authority ecologists, conservation officers and licensing staff within SNCOs and NGOs, and environmental and sustainability managers.

Knowledge Level


Prior Knowledge

Prior knowledge of ecological impact assessments and ecological mitigation, compensation and enhancement design and delivery for development projects is advantageous. Also required is a basic level of knowledge of biodiversity unit calculations, or use of other biodiversity metrics for biodiversity net gain.

CIEEM also run a 'Calculating & Using Biodiversity Units' course which would be valuable to attend prior to attending this course as this will not be covered on the day.

Learning Outcomes

  • Understand the potential role of biodiversity net gain in delivering local and strategic priorities.
  • Communicate the concept and process of biodiversity net gain to stakeholders effectively.
  • Combine qualitative ecological assessments and biodiversity metrics to design biodiversity net gain, including the concepts of habitat trading and ecological equivalency.
  • Understand biodiversity net gain in the context of good practice principles such as additionality, ensuring legacy, promoting connectivity.
  • Develop costed management and monitoring plans, and plan for key requirements during construction.
  • Understand good practice for evidencing biodiversity net gain.


Refreshments will be provided throughout the day. Please bring your own packed lunch.
