Abstract

This study focused on the effects of logging on organisms using bearded pig's mud wallows in Danum Valley Field Centre (DVCA), Lahad Datu, Sabah. The study was conducted in unlogged and logged forest at Danum Valley from June 2006 to July 2006. Thirty two bearded pig's wallows, of which 18 were from unlogged forest and 14 were from logged forest, were sampled and a total of 865 individuals of invertebrates and vertebrates were collected at both sites combined. From the total number of individuals caught, 660 individuals belonged to class Insecta, 52 individuals were from class Amphibia and 153 individuals were captures of other invertebrates. Insecta were the dominant group found in bearded pig's wallows, consisting of five orders, 14 families and 25 species. Amphibia was represented by one order, three families and six species, while other invertebrates were from the class Arachnida, Crustacea, Oligochaeta and Chilopoda. Species richness of organisms associated with bearded pig's wallows were found very similar between sites (Insects; Unlogged forest: 19 species, Logged forest: 21 species)(Amphibia; Unlogged forest: four species, Logged forest: five species) (Other invertebrates; Unlogged forest; seven species, Logged forest: five species). Shannon Wiener and Simpson's Diversity Index showed no significant difference of diversity between both sites (Insects; Shannon-Wiener: P = 0.4359, Simpson's: P = 0.5723) (Amphibia; Shannon-Wiener: P = 0.9457, Simpson's: P = 0.9436) (Other invertebrates; Shannon-Wiener: P = 0.7053, Simpson's: P= 0.4167). A high percentage of similarity (0.60) of composition of species between both sites was obtained. Species were also found to be evenly distributed in unlogged and logged forest (Insects; Unlogged forest: E = 0.7448, Logged forest: E = 0.7264) (Amphibian; Unlogged forest: E = 0.8958, Logged forest: E = 0.7851) (Other invertebrates; Unlogged forest: E = 0.7934, Logged forest: E = 0.9321).
