Metric Errors
In this video, learn about the top level of detail that Mycelia identifies: any errors in the metric.
What Metric Errors shows you
Metric Errors is the first level of detail within Mycelia's Assessment workflow. It brings together every confirmed breach of BNG rules found in a submitted metric into a single, scannable list.
This goes beyond what Excel alone can catch. Mycelia identifies both:
- Spreadsheet errors - the red-cell validation errors that Excel flags within the metric
- Non-spreadsheet rule breaches - errors that fall outside Excel's built-in checks but still represent definite problems
Each error is translated into a plain-English explanation and includes a direct link to the specific habitat record involved, so you can jump straight to the source.
Why it matters
A biodiversity metric spreadsheet can contain up to 20 tabs. Manually reviewing each one for errors is slow and inconsistent. Mycelia collects every confirmed error into one place, so you can see all the problems at a glance without trawling through the entire workbook.
This supports faster, more consistent assessment across your team.
Errors vs. risks
Metric Errors show definite problems - clear breaches of BNG rules that need to be addressed. They are distinct from Ecology Risks, which flag areas that may require professional judgement or interpretation. Errors are black and white; risks involve shades of grey.
Where it fits in the workflow
Metric Errors is Level 1 of the Assessment workflow. It is the natural starting point before moving on to:
- Level 2 - Summary Tables
- Level 3 - Ecology Risks
- Level 4 - Detailed habitat review
Clearing confirmed errors first means you are working from a clean baseline when you move into the more detailed stages of assessment.
