Cabeceira do Rio Acre

What this is

Cabeceira do Rio Acre is an Indigenous territory in Brazil, home to the Isolados da cabeceira do Rio Acre/Yaminawá, covering about 795 km². RAISG records 377 inhabitants. Indigenous-held forest is among the best-conserved in the basin; detections inside it are a measure of pressure on the people who keep it standing.

Detections centred inside · as of 2026-08-23

• Illegal-mining scars: 0 — Amazon Mining Watch, cumulative since 2018
• Deforestation alerts (DETER, 12 months to 2026-08-16): 0 — drawn from the 6,000 largest alerts in the Legal Amazon, so small clearings are not included
• Active fires are a 48-hour feed and change daily — see them live on the dashboard below

A detection counts here when its centre point falls inside the boundary at the time of the monthly bake; extents are the detections' own areas and can straddle the edge. A detection is a satellite-seen change, not a verdict on legality.
