Who observes?

The initial observer is Trần Quốc Thuần, a local host who has spent years on Ben Tre waterways and currently records observations from a monitored river area. Future records may include other identified observers, with provenance retained.

How one record is structured

ID

BTFF-FIELD-YYYY-MM-DD-###

Observation type

First-hand, retrospective, hypothesis, external data or unknown.

Abundance 0–5

A qualitative local scale used only when the observation supports a rating.

Species

Unknown unless a reliable identification process is completed.

Status

RAW, REVIEWED, WEBSITE-READY or REJECTED.

Location privacy

General area may be published; sensitive coordinates are withheld.

Review rules

  • Raw speech is preserved in meaning and never silently “improved” into a stronger claim.
  • First-hand observation is separated from remembered patterns.
  • Weather, tide or lunar data from external services retains its own source and is not attributed to the observer.
  • Missing values remain missing; species and causes are never guessed.
  • Raw records are never published automatically.

Editorial record summary

Fireflies were exceptionally abundant. Unlike the usual local concentration around one tree or a limited display area, they were visible on nearly every locally identified bần tree along the observed stretch. Density varied between trees.

Translation preserves the observer’s meaning; the Vietnamese original is retained for provenance. The record does not identify the species or explain the cause.

What the dataset can become

Consistent records can make local patterns more auditable and help form better research questions. A larger collection of observations is still not the same as a scientific study.
