Species-site matching based on growth performance evaluation of mixed native and exotic secondary forest in Musuan Bukidnon
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2017, Vol 10, Issue 3
Abstract
Species-site matching is an important consideration in rehabilitation efforts to assure success of a program. This study shows a simple method aiding decision makers in selecting species-site match and species combination (native and exotic) based on growth performance evaluation of trees. A total of 478 individuals composed of 12 species (8 endemic and 4 exotic) were assessed in a 30 year old mixed secondary forest in Bukidnon, Philippines. Data of diameter and height was analyzed using Univariate analysis in Brown-Forsythe’s since their is unequal number of samples. Post-Hoc analysis of species performance was compared using Tukey’s Honest Signifincant Difference. Results showed significant difference at <0.01 level of significance among the diameter and height of eight native tree species. The same result was found on exotic species at <0.01 level of significance. Tukey’s HSD on native species revealed significant difference on the diameter and height of Pterocarpus at <0.01 level of significance as compared to Artocarpus, Shorea, Sandoricum and Melanolepis. Tukey’s HSD on exotic species showed significant difference on Gmelina as compared to Swietenia at <0.01 level of significance in both diameter and height. Comparing native and exotic species showed significant difference on the growth of Pterocarpus against Swietenia at <0.01 and Tectona at <0.05 level of significance. Gmelina showed significant difference against Artocarpus (<0.01), Shorea (<0.01) and Sandoricum (<0.05). Species-site suitability concludes that Pterocarpus indicus and Gmelina arborea is the optimum species-mix combination and thus recommended for use in rehabilitation programs in site with similar conditions.
