Data from the Institute of Man and Environment of the Amazon (Imazon) indicates that the reserve is experiencing high levels of deforestation. In August 2026, the area recorded 9 km² of forest loss, making it the second most affected conservation unit in the Legal Amazon for that month. Between January and August 2026, the reserve saw a cumulative loss of 13.8 km², ranking it as the third most deforested unit in the region. While deforestation in the state of Acre rose by 11% in August compared to the previous year, forest degradation caused by logging and fires saw a significant decline of 85% during the same period. ## Timeline ### 2026-09-30: Chico Mendes Extractive Reserve faces high deforestation in Amazon The Chico Mendes Extractive Reserve in Acre is among the most deforested areas in the Legal Amazon, with significant forest loss recorded in 2026 despite a decline in forest degradation. 6 sources. https://clstr.news/cluster/chico-mendes-extractive-reserve-faces-high-deforestation-in-amazon ### 2026-09-25: Chico Mendes Reserve marijuana plantation destroyed by police Police in Acre, Brazil, discovered and destroyed a one-hectare marijuana plantation containing roughly 2,000 plants in the Chico Mendes Extractive Reserve. 4 sources. https://clstr.news/cluster/chico-mendes-reserve-marijuana-plantation-destroyed-by-police --- Cite as: Environmental and illegal activity in Chico Mendes Reserve.
