Doi Inthanon National Park Pursues Legal Action Against Tourists for Damaging Rare Plants
Ten tourists face legal consequences after straying from designated paths at Doi Inthanon National Park to take photos, resulting in damage to rare 'Sphagnum moss' (Khao Tok Ruesi).
On September 17, 2026, Jiraniti Choengsa-ard, head of Doi Inthanon National Park, announced that legal action is being taken against a group of 10 tourists. According to Khaosod Online Thailand, the incident occurred on September 13, 2026, when the group bypassed barriers and warning signs along the Ang Ka Nature Trail to take photographs.
During their excursion, the individuals walked through a field of 'Khao Tok Ruesi' (Sphagnum moss), a rare and highly fragile plant species that thrives only in high-altitude environments above 2,000 meters. Park officials reported visible damage to the moss, noting that the plant grows very slowly. Due to its delicate nature, the trampled areas may take years to recover, and in some instances, the damage could be permanent.
This incident serves as a reminder for travelers and residents to strictly adhere to park regulations and stay within marked trails. Protecting these rare ecosystems is essential for preserving Thailand’s natural heritage. While the park has confirmed the initiation of legal proceedings, the specific penalties the tourists will face remain to be determined by the authorities. Visitors are encouraged to respect signage and barriers to ensure the longevity of these sensitive natural sites.
