Abstract

The objective of this research was to determine the growth in terms of diameter at ground level (D0), total height (Ht), and the relative annual increment (RAI) of selected 5 years old economic tree species, and to determine the species suitable for planting so as to change a Para rubber plantation to be an economic forest. The selection of 10 samples economic tree species was based ranking according to the important value index (IVI) estimated from two demonstration plots at Wang Chan forest learning center, Wang Chan district, Rayong province. A stratified random sampling of selected species was employed for data collection, such as, D0, Ht, and quality evaluation of selected species, which were 9 factors in total. Analysis was done with a statistical software package and simple additive weighting (SAW) method. Data was collected for 4 years from 2016 to 2019


            The results of this study indicated that the highest D0 of economic tree species was of Hopea odorata Roxb. and Dipterocarpus alatus Roxb. ex G. Don, but the highest value of Ht was for Pterocarpus macrocarpus Kurz other while the Archidendron conspicuum (Craib) I. C. Nielsen had the highest RAI for D0 and Ht In conclusion, the economic tree species suitable to be planted in the Para rubber plantation were Hopea odorata Roxb., Dalbergia cochinchinensis Pierre, Pterocarpus macrocarpus Kurz, Dipterocarpus alatus Roxb. ex G. Don, Aquilaria crassna Pierre ex Lecomte, Archidendron conspicuum (Craib) I. C. Nielsen, Knema globularia (Lam.) Warb, Millettia xylocarpa Miq, Afzelia xylocarpa (Kurz) Craib, and Shorea henryana Pierre with a suitable score of 67, 62, 59, 57, 53, 52, 51, 49, and 38 percent, respectively.
