May 23, 2026 · 3 min readBrazil's Atlantic Forest cut deforestation to just 8,658 hectares in 2025, its lowest annual loss since monitoring began, even as climate-driven fires keep pressuring the country's other biomes.
The milestone signals momentum behind global reforestation efforts, but scientists warn that agriculture, wildfires, and silent forest degradation still threaten Brazil's progress and the world's broader deforestation goals.
The biome dropped below 10,000 hectares of annual loss for the first time since SOS Mata Atlântica and partners began tracking in 1985.
Atlantic Forest losses fell 40% from the prior year, a swing environmentalists credited to stronger enforcement under President Luiz Inácio Lula da Silva.
The biome contains about 24% of its original forest cover and shelters roughly 80% of Brazil's population, making it the country's most urbanized and degraded ecosystem.
SOS Mata Atlântica director Malu Ribeiro warned that a recently enacted measure, the General Environmental Licensing Law (PL 2159/2021), which critics call the 'devastation bill', weakens environmental licensing for infrastructure, mining, and agriculture projects and could undo years of conservation work, Context reports.
Globally, tropical forest loss fell 36% in 2025 after hitting an all-time high in 2024, the World Resources Institute reported.
Roughly 4.3 million hectares of primary rainforest vanished across the tropics in 2024, driven largely by agricultural expansion and fires, an area about the size of Denmark.
Brazil drove much of the global improvement, slashing non-fire primary forest loss (clearing from agriculture, logging, and infrastructure, separated from wildfire-driven loss) by 41% as Lula relaunched the PPCDAm federal anti-deforestation plan.
Fires, including Brazil's record Pantanal blazes that began in June 2024 and Amazon hotspots that peaked in September 2024, complicated the picture, accounting for 42% of global tree cover loss in 2025 and threatening to undo recent policy gains as climate change intensifies wildfire risk, Mongabay reports.
Agriculture continues to dominate as the long-term driver, with pasture expansion for cattle responsible for about 41% of tropical deforestation each year.
Cattle ranching alone explains roughly 72% of Brazilian deforestation, dwarfing soy and oilseeds, which account for about 18% of the global tropical total.
Government efforts to reverse the damage took a new turn in March 2026 when Brazil awarded its first public reforestation concession to local startup Re.green.
The company will restore roughly 145,000 acres of Bom Futuro National Forest, located in Rondônia state in Brazil's western Amazon, over a 40-year term.
Re.green is/has committed to pay the government 0.7% of carbon-credit revenues, an arrangement projected to yield about $2 million each year.
Environment Minister Marina Silva framed the concession as a way to turn negative deforestation losses into a positive engine for restoration funding.
Authorities have identified 3.2 million acres suitable for similar concessions and aim to auction up to 750,000 acres by 2027.
The Atlantic Forest Pact, launched in 2009 across 17 Brazilian states, targets restoration of 15 million hectares by mid-century.
About 75% of land in the biome remains under private ownership, making landowner participation central to whether restoration projects can reach scale.
Researchers tracking the pact argue that a robust market for native plants, seeds, and seedlings will determine whether private landowners commit to the costlier work of replanting indigenous species.
Roughly 60% of native plant species in current restoration zones carry economic potential in medicinal, cosmetic, and food sectors, the researchers found.
The Atlantic Forest milestone, therefore, arrives with sober caveats from scientists, environmentalists, and government regulators about what restoration actually requires.
Brazil's broader Amazon biome, although still a net carbon sink, faces accelerating degradation from wildfires, droughts, and selective logging that thin the canopy without clear-cutting it.
Climate scientists warn the rainforest could cross a tipping point if degradation accelerates, even as headline deforestation rates fall.
The 2025 Atlantic Forest record still anchors a hopeful turn in the broader global story, with reforestation, policy enforcement, and market-driven restoration each gaining ground heading into 2026.
