The biodiversity metric 2.0

Closes 31 Dec 2019

Opened 29 Jul 2019


Natural England has been working with Government and other stakeholders to update and improve the 2012 Defra biodiversity metric for measuring biodiversity losses and gains. This updated metric is called the biodiversity metric 2.0 and it supersedes and replaces that earlier Defra biodiversity metric. Biodiversity metric 2.0 can be used to calculate a biodiversity baseline and to forecast biodiversity losses and gains (on-site or off-site) resulting from development or land management changes.

Why We Are Consulting

The biodiversity metric 2.0 has been published by Natural England as a beta test version for comment and feedback. This survey is designed to help capture feedback and comments on biodiversity metric 2.0 in order to inform a further revision. This survey will remain 'live' until the end of December 2019. The metric will then be further updated (as needed) in 2020. This survey builds on the questions asked about the proposed approach set out for biodiversity metric 2.0 that was published at the end of November 2018 in support of Defra's net gain consultation.
