The Department for Environment, Food and Rural Affairs (Defra) metric is a habitat-based approach to determining a proxy biodiversity value to enable the assessment of change in that value. 2. Government will improve environmental mapping. A beta-test version is expected later this year, with a final version expected to be released in 2020. Global biodiversity loss is intensifying. The HBA’s remit was to survey every field and boundary in the sub-region to provide up-to-date biodiversity data. Other (please provide an explanation) Please provide any explanation for your answer here: We have no expertise in this area. The updated metric is described and short summaries are provided to describe the component parts and multipliers. Planning for a 10% Biodiversity Net Gain 7 November 2019 By Enzygo 0. A robust metric to measure Biodiversity Net Gain is vital. 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. 5. so that biodiversity impacts can be better avoided in the first instance. It: The Species Protection Index capitalizes on detailed remote sensing data, a global biodiversity informatics infrastructure and integrative models. Natural England has committed to updating the ‘biodiversity unit’ metric issued by Defra. Determining biodiversity credit class 43 10.1.Determine ecosystem credit class 44 10.2.Determine species credit classes 45 11. 10. Biodiversity net gain is an approach which aims to leave the natural environment in a measurably better state than beforehand. 10 Is the Defra biodiversity metric an appropriate practical tool for measuring changes to biodiversity as a result of development? The data is held on a Geographical Information System (GIS), which provides high-quality coded maps and linked site notes with a powerful tool for interpretation and statistical analysis. Updating existing cases 47 13. Defra, in co-ordination with Natural England and a small task group of experts (including us) are in the process of updating the metric which will include a new national calculator. News We this the Defra Menc gu. The metric does not assume compensatory actions will be required and can demonstrate that on-site biodiversity net gain has been achieved. Blog This could improve how the planning system addresses development’s impact on habitats, allowing new housing without negatively impacting our wildlife. Biodiversity net gain tools and guidance will reinforce and support adherence to the mitigation hierarchy which is already well established in planning policy. The beta metric can be downloaded from; Please refer to and use the above beta metric which supersedes this summary document. A number of these systems are underpinned by a metric which allows impacts on nature to be quantified in standard biodiversity units. Contact Us. Metric Update – we would just like to advise you that the launch of The Biodiversity Metric 3.0 (the successor to the beta test metric 2.0) has now been re-scheduled to Spring 2021. The metric is a habitat based approach to determining a proxy biodiversity value. 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.
