Doi Suthep–Pui National Park in Chiang Mai is one of the most visible areas where illegal forest burning frequently occurs during the dry season, with smoke and haze affecting the health of tourists and residents both on the mountain and in Chiang Mai city, as well as damaging forest resources and wildlife.
Most recently, Thongchai Narat, Head of Doi Suthep–Pui National Park, has deployed park officials together with Phu Phing Forest Fire Control Station and the 33rd Military Circle to carry out a proactive, door-to-door campaign in communities surrounding Doi Suthep. The teams are informing residents about Chiang Mai Province’s strict no-burning order in effect from 1st January to 31st May 2026, while raising awareness of the dangers and impacts of PM2.5 air pollution. The campaign aims to reach all 54 villages around Doi Suthep in Muang Chiang Mai and Hang Dong districts.
Meanwhile, air quality in Chiang Mai on 4th February 2026 continued to deteriorate, with PM2.5 levels exceeding safety standards in several districts and haze becoming increasingly visible. The highest hourly PM2.5 reading was recorded in Chai Prakan district at 77 micrograms per cubic metre. Authorities said the main contributing factors remain stagnant weather conditions, light winds, and ongoing agricultural burning, causing pollution to accumulate in the atmosphere.
