Forest loss, Salonga National Park core (DRC): 15.26 ha in 90 d
Salonga National Park core (DRC) · seen
1241 GFW integrated deforestation alerts (≥ high confidence) covering 15.26 ha between 2026-06-28 and 2026-09-26; AOI alert density is 1.678× its 25 km neighbourhood. Awaiting optical confirmation.
What we saw
- Area: 15 hectares — about 21 football fields
- Global Forest Watch alerts — 1241 alerts (≥ high confidence), 15.26 ha, 2026-06-28…2026-09-26. (Sep 26, 2026) See the source ↗
What it might not be
- Coverage is 30°N–30°S only — zero alerts outside the tropics means 'not monitored', not 'no loss'.
- Cannot distinguish legal clearing, fire, storm damage and selective logging from illegal clearing; attribution needs concession/protected-area layers (M3).
- Alerts lag reality by ~1–2 weeks; a burst just before the sweep is undercounted.
- Regrowth and plantation harvest cycles look like loss; the baseline ring only partly compensates.
- Persistent cloud can delay optical confirmation for months (SAR-only RADD alerts stay 'candidate').
What would change our mind
Newer satellite images that show no change, a correction from the data source, or a reply with evidence from the ground. If that happens, the case is marked “Turned out wrong” — in public — and it stays on this site.
Why this is not published
Never published: on a closer look it turned out wrong. It stays on this site so mistakes are counted, not hidden.
Right of reply
If a case names or affects you, you can reply. A reply channel that keeps both sides on record is being set up; until then, every case page carries its ledger id so a reply can be attached to it.

Publication gates
- Evidence — 1 piece from gfw-integrated-alerts — met
- Independent confirmation — not yet — not met
- Human approval — 0 of 1 needed at tier 1 — not met
Publication is decided by the ledger’s rules, not by the AI: the event that publishes a finding is refused unless every gate above is met.
