Defra introduce updated biodiversity metric 2.0


Biodiversity metric

Defra along with Natural England and other key stakeholders have been working with the aim of updating and improving the 2012 Defra biodiversity metric which measures biodiversity losses and gains.

The proposed updated Defra Biodiversity Metric is designed to provide ecologists, developers, planners and other interested parties with a means of assessing changes in biodiversity value (losses or gains) brought about by development or changes in land management.

What the new metric includes:

  • Improved consideration of ecological connectivity
  • Covers an extended range of habitat types including green infrastructure and rivers
  • A forthcoming spreadsheet-based tool will support the application of the metric in practice

The metric can be used now, however feedback provided from users will be used to inform a further update, to be released in 2020. Download the biodiversity metric 2.0 here:
