The Biodiversity Metric
The Biodiversity Metric published Natural England provides a way of measuring and accounting for biodiversity losses and gains resulting from built development or a change in the way land is managed. It is designed for use in England. A Biodiversity Metric 3.0 was released in July 2021. It is supplemented by a Small Sites metric, which is currently available as a ‘beta’ test version. The Small Sites Metric is intended for use according to specific criteria for the size of the development, and where there is no priority habitat present.
