Valuation of a man-made dipterocarp forest as seed source for Shorea red meranti (Dipterocarpaceae)

Abstract

Lack of good quality seeds has been one of the constraints in icreasing the success rate of rehabilitation, restoration and establishment of plantation forest. Establishing seed sources is a way to increase the availability of qualified seeds for various purposes. Gunung Dahu Research Forest (GDRF) has Shorea pinanga and Shorea platyclados (Dipterocarpaceae) stands that has potential to meet the standard of identified seed stands (ISS). We evaluate two stands of S. pinanga (plot 05 and 24) and four stands of S. platyclados (plots 04, 15, 20, and 21e) to be quantified for their potential as ISS. Assessment was carried out by evaluating the parameters related to number of mother trees, accessibility, stand quality, management, fruiting history, and origin. Among all assessed plots, highest final score was obtained by plot 20 (131.5), followed by plot 24 (112.5), plot 05 (105.5), plot 04 (87), plot 21e (85), and plot 15 (57). Based on the minimum score of 94.5, the potential plot that can be assigned as ISS are plot 05, plot 24 and plot 20.
