Mata Grande

What this is

Mata Grande is a floresta nacional — a legally designated protected area in Brazil, covering about 20 km², established in 2003. Administered at the nacional level. What is permitted inside depends on the category — strict reserves allow almost nothing, national forests and extractive reserves allow managed use — so a detection here is a reason to look, not a verdict.

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.
