The Nan Project

The Nan Project, directed by Assist. Prof. Dr. Dia Shannon comprises 3  research initiatives:

1. From a Bare Mountain to a Regenerated Forest: compared landscape planting designs for forest restoration in Nan Province, sponsored by the National Science and Technology Development Agency (NSTDA), 2017 to 2020.

2. Forest Landscape Restoration and Community Well-being: supported by the Program Management Unit on Area Based Development (PMU A), 2020 to 2021.

3. Evaluating Changes and Ecosystem Services of Nan Restored Forests: funded by the National Science and Technology Development Agency (NSTDA), 2021 to 2022.

The research spans three districts of Nan Province—Pua, Phu Phiang and Wiang Sa—with three plots in each  district. The project commenced with a survey of reference forest remnants, near the restoration sites, including i) the Nam Kaen - Nam Sa Watershed Forests (Phu Phiang District), supervised by the Royal Forest Department; ii) Mon Hin Kaew Community Forest (Pua District) and iii) Ban Muang Noeng Community Forest (Wiang Sa District). The survey involved documenting tree density, species diversity and phenology, as well as bird diversity, over three years. Such data were then compared with the same in restoration forests, established in the 3 districts.

Knowledge of the framework species method of forest ecosystem restoration was transferred to local communities and restoration plots of various sizes were planted with a range of indigenous framework tree species. Post-restoration activities include frequent weeding and fertilizer application, as well as the cutting of firebreaks in the dry season. Monitoring focused on survival and growth rates of each species, as well as the diversity of soil microbial communities. Ecosystem services, provided by the restored forests, including climate control, were evaluated, along with forest products used by local people. The effects of restoration on the quality of life of local people was also assessed. Currently, villagers who are project members continue to actively contribute to the care of the restored forest, to ensure its long-term health and growth.
