HabitatCheck — Delivered biodiversity features
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
Compliance with best practice of delivered biodiversity features (nest boxes, ponds, hedges, roofs, lighting, vegetation, water) — and, in PRO, their observed ecological functionality (occupancy, breeding, plant establishment). Performance is proven, not declared (ADIVET); without evidence, no credit is given (conservativeness, ACT).
How it computes
Score = compliance rate weighted by point criticality (published, sourced 1/2/3 grid), over the assessed points. Eliminatory rule: a criticality-3 non-conformity caps the displayed score at 59/100 (an untreated critical point cannot read « Good »). Three thematic sub-scores (functionality / vegetation / lighting) feed the BPS. Each recommendation is backed by a recognised method producer.
22-point checklist, recommended photo evidence, displayed declarative status (« declared, not audited »), indicative V1 / V2 / V3 visits.
Checklist configurable by feature type (re-normalisation), mandatory geolocated photo evidence, observed-functionality criterion (refuge / breeding / feeding / connectivity), scheduled visits signed by an ecologist. Feeds the BPS « post-delivery functionality control » module.
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
In LITE, declarative status (« declared, not audited »); does not amount to a regulatory control or an audit.

Training the teams who use these tools.
A one-day course gives the ecological reference points these tools assume: recognising what is being recorded, understanding what a protocol requires, and knowing what makes a survey usable.
