Any individual found encroaching on conserved forests or national forest reserves in Chiang Mai—which are closed to all unauthorised access—will be arrested immediately and face charges, according to a recent directive issued by the provincial governor to police and park rangers in a bid to curb forest fires.
A total of 244 hotspots were reported in Chiang Mai today, including 37 in Prao district and 33 in Chiang Dao district. Many of these fires are located on high mountains that are not easily accessible by foot patrols and require air support to extinguish.
National park officials say some of the fires are being deliberately set by encroachers. Evidence includes dried branches and leaves placed across firebreaks to allow flames to spread beyond them.
Widespread wildfires in Chiang Mai have been blamed for worsening PM2.5 pollution. Air quality has slightly improved today, with pollution levels in some areas dropping from the Purple category to Red or Orange.
Residents are still being advised to wear face masks outdoors and to avoid outdoor activities where possible.
The Air Pollution Response Communication Centre reported today that PM2.5 levels in all northern provinces remain above the acceptable limit of 37.5 micrograms per cubic metre.
In addition to Chiang Mai, where 244 hotspots were detected, other northern provinces reporting high numbers include Nan (287), Chiang Rai (283), Lampang (278), Tak (180), Phayao (143), Phetchabun (136), and Uttaradit (116).
