A design change can leave several versions of the BNG evidence in circulation. Keep a short revision trail that connects the changed layout with the habitat drawing, metric workbook and supporting report. The aim is to make the change visible to the people responsible for reviewing it before the next issue.
Describe the change before circulating the drawing
Explain what changed, where it is shown and why the team needs a decision. A new path, altered boundary or revised planting arrangement should have a drawing reference and a dated change note. Separate a proposed change from an agreed instruction. That distinction helps an ecologist understand whether they are reviewing an option or updating the evidence for a settled design.
Keep the earlier coordinated set available. Comparing two identifiable revisions is more reliable than asking contributors to remember which layout their work used. Mark superseded copies clearly, without deleting the project record.
Trace the affected evidence
Ask the relevant authors which documents rely on the changed information. The list may include the habitat plan, workbook, report, management proposals and submission documents. A drawing issue alone does not establish that the technical implications have been addressed.
Record the person responsible for each response. Where a change raises an assessment question, seek a review of its ecological scope rather than editing a figure to match the new plan. Application-stage evidence and later Gain Plan documents should remain identifiable as separate deliverables.
Close the loop with an issue note
When the response is agreed, circulate a coordinated document register. Include unchanged documents as well as revised ones, so recipients know what belongs in the new set. Give unresolved questions a named owner and explain which decision they affect.
A review response should say what was considered and whether another contributor needs to act. An email saying ‘updated’ can be too ambiguous if the landscape plan changed but the workbook or report still needs attention.
Information register
| Change reference | Location, description and originating drawing |
|---|---|
| Affected evidence | File, revision and responsible author |
| Response | Reviewed action or an unresolved question |
| Issue status | Proposed, agreed, issued or superseded |
A practical example
Illustrative example: An access path moves between layout revisions. The coordinator identifies the affected habitat parcel and sends the revised drawing to the ecologist. The response log records which evidence needs updating and which documents remain valid for that issue.
Before the next issue
- The starting document set is identified.
- The change has a location and revision reference.
- Each affected document has a review owner.
- Open questions are visible in the issue note.
- Recipients can distinguish the current set from earlier drafts.
For the relevant specialist scope, see BNG assessment, Biodiversity Gain Plan.
Professional context: Government BNG planning guidance, Official statutory metric tools and guides.
