FaunaLog — Common wildlife survey
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
The richness and heritage value of the common wildlife contacted, at bounded observation effort — not a mere « contact quality ». Species richness is the reference biodiversity metric (OID, IUCN, Vigie-Nature).
How it computes
Score = heritage-weighted relative richness (IRP): the denominator is a fixed (regional) reference species pool, so each observed species raises the score — richness and rarity are finally reflected. Contact quality (abundance × phenology) and inventory completeness (anti under-sampling safeguard) are returned as secondary indicators, at constant effort, in the spirit of Vigie-Nature surveys (STOC-EPS, STERF).
Minimal standardised protocol (fixed duration, time and calendar windows, ≥ 2 visits), tightened regional reference list, bonus photo/audio evidence. Awareness tool, no regulatory value.
Observation-effort correction, regionalised reference list (ZNIEFF determining species + regional red lists), mandatory geolocated evidence, completeness estimator (Chao1 / jackknife). Feeds the initial fauna state, monitoring and the ITCE (initial state / regulatory framework).
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 detection with no regulatory value; the score reflects richness and heritage value at bounded effort, qualified by inventory completeness (a site may be « to complete » rather than « poor »).

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.
