Defra metric

Natural England wants to start working with others to update the Defra Biodiversity Metric originally developed for the 2012 Biodiversity Offsetting Pilots.  We want to produce an initial update in September 2018 and then produce subsequent updates on an iterative basis. To help inform our initial thinking we have developed this questionnaire to seek your and your colleague’s views on the current ‘Defra Biodiversity Metric’ and how it could be improved.
The survey takes no more than 5 minutes to complete. Please could you complete it by Friday 19 January 2018.

Please feel free to forward the survey link to other colleagues within your organisation.

We will communicate a summary of the survey results and will be inviting those of you who express an interest to work with us to inform this update to the Metric.

1. The habitat type bands and distinctiveness categories used in the 2012 Defra Metric are:


2. The habitat distinctiveness multipliers used in the 2012 Defra Metric are:


3. The habitat condition weightings used in the 2012 Defra Metric are:


4. How easy do you find it to do the calculation for the current baseline and then the post-impact calculation using the existing 2012 version of the Defra Metric?


5. Would you find it useful to have a simple-to-use, nationally recognised, spreadsheet-based tool to help you calculate Biodiversity Net Gain?


6. The multipliers for different categories of delivery risk are:


7. The multipliers to deal with spatial risk:


8. The multipliers to deal with linear environmental features such as hedgerows, ditches and watercourses are:


9. Please indicate areas where you feel changes/additions to the Defra Metric would be useful (tick as many as required)


10. Please indicate areas where you feel changes/additions to the Defra Metric would be useful and rank them in the order of priority from 1- 14, with one being the highest priority for change.


11. The condition assessment methodology for a revised Metric should be based on:


12. Please indicate the extent to which you agree or disagree with the following statements.

A future biodiversity metric to measure net gain should:

Strongly agreeAgreeDisagreeStrongly disagreeDon't know
recognise the distinction between habitat enhancement/restoration and habitat creation
treat habitat creation as a change from one broad habitat type to another, and enhancement / restoration as a change within the same broad habitat type
not seek to account for irreplaceable habitats and it should be accepted that any development likely to affect such habitats should be addressed through the application of the mitigation hierarchy
ensure that compensation measures do not result in “trading down" i.e the area, quality and condition of the replacement habitat should be of equal or greater value over an acceptable time frame than the one being lost
for a given habitat, seek to account for its ability to be recreated or enhanced; its area or length; its distinctiveness, its condition and its spatial relationship with other habitats
be able to account for more than compensation provision for habitat losses under a range of circumstances either elsewhere on site or off-site or both
be able to account for expanding the area/length of a particular habitat or enhancing the condition of an existing area of habitat
be able to account for recreating an appropriate area of a particular habitat to a particular condition over an acceptable timescale either elsewhere on site or off-site or both
be able to account for the loss of one habitat of a given size, location and condition and it's replacement with a different habitat of equal biodiversity value either in the same location, elsewhere on site or off-site
include a translation tool to enable condition assessment data to be translated across a range of formats e.g. Phase 1 to UK Habitat Survey

13. Would you like to be involved in any work to revise the metric ?
