BiodivPass — Express regulatory check
The BIOM365 tools' methodology is published and grounded, indicator by indicator, in the field's reference work: each tool sets out what it measures, how it computes it, its sources and its limits.
Use the tool →What it measures
A self-assessment for orientation: from 10 declarative questions, it estimates a project's likely biodiversity stakes and points to the right approach. It is not a field measurement.
How it computes
Three axes — regulatory risk (R), ecological potential (P), project maturity (T) — combined into an exposure score; weightings and thresholds shown. The ACT framework bounds its use: a score should not rise because one declares better, but because the project genuinely improves.
100 % declarative, results in under two minutes, explicit orientations (from « Contained exposure » to « Immediate action »), a call to action toward an ecologist / a study.
At least the risk axis is cross-checked with real geolocated data (via TerraLink: Natura 2000, ZNIEFF, reserves, Green & Blue Network); un-merged R / P / T output; weighting driven by the site's materiality; thresholds calibrated on benchmark projects; output = study pre-scoping and ERC hierarchy (avoidance first).
Common methodological foundation
- Verifiability — a data point carrying a score must be provable — mandatory in PRO.
- Conservativeness — without evidence, we do not overestimate; declarative input is flagged.
- Consistency — any time-series data is comparable — bounded observation effort.
Two quality indices accompany each score: a reliability index (input completeness; below a threshold the score reads « not computable ») and a confidence index (traces the source of each value; by convention, the lowest of its components' indices).
On screen: a 0-100 score + a one-word label + a colour. Performance axis (Excellent / Good / Fair / Low / Critical), thresholds aligned with the internal grade so a displayed score and its history never contradict each other. Exposure axis for BiodivPass and TerraLink (Contained exposure → Immediate action).
Thresholds and weightings rely on the guide-values and reference frameworks cited, and are consolidated continuously with the scientific committee (Biodiversity Standard Council).
Stated limit
A declarative orientation tool; it does not replace an environmental study or an ecologist's opinion.
