Main Article Content
Abstract
Phu Hung community forest, Thum Tong Subdistrict, Mueang Nan District, Nan Province, Thailand currently meets
with the situation of “forest surrounded by houses”, it may finally deteriorate and transform. Therefore, guidelines on increasing
economic plants and utilization corresponding to vegetation diversity was analyzed. The survey on the area focused on the
temporary sample plot of 1ha obtained by subjective sampling. Value added and forest conservation to make this area perfectly
livable for humans with the forest should be implemented in compliance with planting promotion policy for 58 species and the
royal remarks of H.M. King Bhumibol Adulyadej about 3 Forests, 4 Benefits. It was found that the study area was a secondary
mixed deciduous forest with 3crown classes. There were 424 plants from 59 species, 52 genuses, and 29 families. Lamiaceae
had the most species, particularly Vitex canescens, the plant with the highest relative density, relative frequency, relative
dominance, and importance value indices up to 19.10, 14.49, 15.07 and 48.66%, respectively. This area had species diversity
index = 3.28, evenness index = 0.80. Key plants that should be promoted for planting included Grewia paniculate, Lamiaceae,
Cassia fistula, Pterocarpus macrocarpus, Albizia lebbeck, and Lagerstroemia floribunda, Dipterocarpaceae and all species of
bamboos
