Chiang Mai University uses research and technology to restore Doi Suthep’s forests, preserve cultural sites, and promote environmental awareness.
Doi Suthep holds deep cultural and spiritual significance for Chiang Mai residents. For over 700 years, it has provided essential resources like water and timber. Today, it plays a major role in tourism and the local economy. However, deforestation and habitat destruction threaten its biodiversity, making conservation efforts essential.
Thailand once lost natural areas at an alarming rate of six percent per year. Widespread deforestation, soil erosion, and frequent wildfires led to severe environmental damage. In response, CMU established the Forest Restoration Research Unit (FORRU-CMU), a team of ecologists and students from the Faculty of Science. This group focuses on restoring forest ecosystems and preserving biodiversity. Research also includes studying the carbon storage potential of restored forests. Findings are shared through workshops for organizations and individuals interested in conservation.
Dr. Stephen Elliott, co-founder of FORRU-CMU, emphasized that forest restoration is a long and complex process. Protecting ecosystems and improving degraded land requires systematic action. To support biodiversity and fight climate change, FORRU-CMU collects forest samples, stores seeds, and develops seedlings for reforestation. Drone technology helps monitor restoration progress by capturing aerial images and comparing regrowth in different areas. Future projects may include using drones to disperse seeds over large sites.
Beyond environmental restoration, CMU researchers explore Doi Suthep’s cultural history using astronomical analysis. A study of Wat Phra-Tat Doi Suthep’s ordination hall revealed that its axis is aligned at 59.74 degrees north, with the entrance facing 30.26 degrees northeast. This alignment does not match the sun or moon but corresponds with the rising of the Corona Borealis constellation, known locally as Khop Dong or Visakha. Historical records from 1537 indicate that this constellation marks the Visakha month, when Chiang Mai locals traditionally ascend Doi Suthep to pay respects at the temple. Assistant Professor Dr. Siramas Komonjinda from the Physics and Material Science Department explained that this alignment reflects a deep connection between local culture, nature, and astronomy.
To promote conservation and education, CMU established the Doi Suthep Nature Centre as a hub for research and awareness programs. Scholars use their expertise to organize activities focused on ecology, ornithology, and population studies for all age groups. Associate Professor Dr. Prasit Wangpakapattanawong, the centre’s director, stated that their work supports Doi Suthep-Pui National Park while educating the public on environmental conservation.
The Doi Suthep Nature Centre offers a range of resources, including exhibitions, a seed bank, and educational events for young people. It also serves as a tourism centre, providing guided nature interpretation services. These efforts aim to build a strong conservation network and encourage a culture of environmental responsibility.
