Vegetation Structure Diversity and Value-Added Guideline Corresponding to Biodiversity for Phu Hung Community Forest, Thum Tong Subdistrict, Mueang Nan District, Nan Province, Thailand

Abstract

Phu Hung community forest, Thum Tong Subdistrict, Mueang Nan District, Nan Province, Thailand currently meetswith the situation of “forest surrounded by houses”, it may finally deteriorate and transform. Therefore, guidelines on increasingeconomic plants and utilization corresponding to vegetation diversity was analyzed. The survey on the area focused on thetemporary sample plot of 1ha obtained by subjective sampling. Value added and forest conservation to make this area perfectlylivable for humans with the forest should be implemented in compliance with planting promotion policy for 58 species and theroyal remarks of H.M. King Bhumibol Adulyadej about 3 Forests, 4 Benefits. It was found that the study area was a secondarymixed deciduous forest with 3crown classes. There were 424 plants from 59 species, 52 genuses, and 29 families. Lamiaceaehad the most species, particularly Vitex canescens, the plant with the highest relative density, relative frequency, relativedominance, and importance value indices up to 19.10, 14.49, 15.07 and 48.66%, respectively. This area had species diversityindex = 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 ofbamboos
