In 2025, the Mekong region experienced a significant slowing of deforestation rates with a nearly 25% reduction from the previous year, yet the area still lost nearly 746,000 hectares of tree cover, highlighting ongoing environmental pressures.
- Mekong region lost 746,168 hectares of tree cover in 2025.
- Deforestation rate dropped nearly 25% compared to 2024.
- Cambodia's protected areas saw over half their losses.
What happened
In 2025, the Mekong countries—Cambodia, Laos, Myanmar, Thailand, and Vietnam—lost approximately 746,168 hectares (1.8 million acres) of tree cover, an area about the size of the Bangkok Metropolitan Area. Of this, over 154,000 hectares were primary forests, which are vital for biodiversity and ecosystem health. Nearly 200,000 hectares of forest loss occurred within protected areas where deforestation is supposed to be tightly controlled.
Despite these substantial losses, the overall deforestation rate declined by almost 25% from 2024 levels. This decline is part of a trend that began in 2023 and is attributed to factors such as fewer wildfires, increased rainfall, stronger law enforcement, and reduced commodity prices. However, experts caution that this short-term drop does not necessarily indicate a lasting reversal of deforestation trends.
Why it feels good
The reduction in deforestation rates across the Mekong countries points to promising progress in conservation efforts and environmental management. Cambodia, for instance, recorded its best year for forest protection since 2003, with tree cover loss dropping by roughly 50% compared to 2023. Such improvements suggest that efforts to curb illegal logging, control wildfires, and manage land clearing may be starting to take effect.
Moreover, the decline across all Mekong countries underscores the potential impact of coordinated regional policies and environmental awareness. The combination of natural factors like milder droughts and human factors such as stricter law enforcement offers hope that the forests may stabilize if these positive conditions continue.
What to enjoy or watch next
While the regional drop in deforestation is encouraging, the ongoing losses—particularly in protected areas such as Cambodia’s Beng Per Wildlife Sanctuary and Prey Lang Wildlife Sanctuary—highlight the urgent need for continued vigilance and on-the-ground management. There remains a strong threat from infrastructure development, mining, and monoculture plantations that could undermine these gains.
Looking ahead, it will be important to monitor whether the deforestation rate continues to decline or if the losses rebound. Stakeholders and conservationists are watching closely to see if improved law enforcement and investment in sustainable land use practices can sustain this positive trend and protect these vital ecosystems for future generations.
