ANALYSIS OF COMMUNITY STRUCTURE OF MELIENTHA SUAVIS (PAK WAAN PAA) FOREST NEARBY HUAY HIN DAM VILLAGE, HOD DISTRICT, CHIANGMAI

Abstract

The analysis of community structure of the Dry Dipterocarp Forest where Melientha suavis (Pak Waan Paa) is grown naturally was carried out in the forest adjacent to Huay Hin Dam Village, Hod District, Chiangmai, between 1991 1993. Results showed that where Melientha suavis in this forest was relatively abundant as compared with other locations. The quantitative description reported involving frequency, abundance, density, dominance and important value index of different trees, including Melientha suavis. The dominant tree is Shorea siamensis with 100% frequency, abundance of 62.18, relative density of 48.93%, dominance of 51.83% and important value index of 106.13. Other trees such as Shorea obtusa, Dipterocarpus obtusifolius and D. tuberculatus had the small values. Melientha suavis had frequency of 100%, abundance of 3.64, density of 3.18%, dominance of 2.67% and important value index of 11.22. It is implied that Mehentha suavis had the low density. It is assumed that the species will be distinct in most forests in the near future.
