From: Near-complete loss of fire-resistant primary tropical forest cover in Sumatra and Kalimantan

Primary forest % cover the region’s peatlands (orange through red) and non-peatlands % (green through blue) at the beginning of 2019. The categories shown are <99% primary forest cover, primary forest cover >99% but within 2 km from the forest edge, and primary forests cover >99% and further than 2 km from the forest edge.
