Biodiversity Net Gain

Biodiversity Net Gain (BNG) is an approach that ensures habitats for wildlife are left in a measurably better state than they were before development. In England, BNG is mandatory; developers must demonstrate and deliver an increase in biodiversity following their development of 10%.

In the last episode of this series, we hear from ecological consultant and future host of this podcast, Harry Fisher. We discuss his experience of BNG and how it works, including biodiversity metrics, valuing nature, opportunities for Scotland and what he is looking forward to as the future host of Natural Capital.

If you have an idea for future episodes, or want to provide feedback on the series, we would love to hear from you. Visit:

Host Rachel Smillie, Producer Iain Boyd, Executive Producer Kerry Hammond, Editor Ross Mackenzie.
