CHIANG MAI – Authorities in Chiang Mai have arrested 43 individuals for violating emergency forest closure orders as part of an intensified campaign to combat illegal burning and seasonal haze. The arrests come as officials tighten security across protected woodland areas to prevent forest fires, which have historically plagued the region during the dry season.
The Chiang Mai Provincial Administration confirmed that the legal actions are a direct response to unauthorized entry into protected forests. Despite a strictly enforced ban, individuals continue to enter these zones, primarily to forage for forest products or clear land for agriculture using fire.
Security forces and forest rangers have increased their presence in high-risk areas. Officials noted that the primary cause of recent fires is human activity, often driven by traditional foraging habits and local beliefs regarding land management.
“We are maintaining a 24-hour watch in areas prone to burning,” a provincial spokesperson stated during a press briefing. “The 43 cases filed so far serve as a stern warning that forest violations will carry legal consequences.”
The geographical challenges of Chiang Mai exacerbate the fire risk. Much of the province consists of mixed deciduous forests where leaf litter accumulates rapidly. This dry organic matter serves as highly flammable fuel, and the steep, mountainous terrain makes it difficult for firefighters to reach and extinguish outbreaks once they begin.

Impact of Forest Closures and Fire Prevention
To mitigate the environmental damage, the provincial government implemented a temporary closure of forest reserves. This measure aims to reduce human-induced sparks during the peak of the dry season. Key points of the current enforcement include:
- Strict Surveillance: Manning checkpoints at all major entry points to national parks and forest reserves.
- Legal Prosecution: Immediate filing of charges against those caught with fire-starting equipment or found within prohibited zones.
- Fuel Management: Controlled collection of dry leaves in accessible areas to reduce the “fuel load.”
- Community Outreach: Educating local villagers on the health risks associated with PM2.5 dust particles caused by smoke.
The crackdown is part of a broader regional effort to improve air quality. Chiang Mai frequently tops the list of the world’s most polluted cities during the early months of the year due to trapped smoke. By reducing the number of forest fires, authorities hope to lower the levels of hazardous PM2.5 dust that affects millions of residents and tourists.
While the number of “hotspots”—areas detected by satellite as having high temperatures—has fluctuated, the presence of security personnel has successfully deterred large-scale arson in several districts. However, officials warn that the risk remains high until the arrival of the monsoon rains.

Environmental and Health Risks
Forest fires in Northern Thailand do more than just destroy timber; they disrupt local ecosystems and cause severe respiratory issues for the public. The Department of National Parks, Wildlife and Plant Conservation has deployed additional units to assist Chiang Mai’s local teams in monitoring the vast, rugged landscape.
“Our goal is not just to arrest people, but to protect the lungs of our province,” the provincial report noted. The government continues to urge citizens to report any sightings of smoke or illegal entry into the forests to help preserve the region’s natural resources and public health.
