Ant species assemblages in old-logged forest and unlogged forest in western Sinharaja, Sri Lanka: investigating remnant effects of selective logging
MetadataShow full item record
The residual effects of logging on forest fauna and flora have been well studied in other regions of the world, with many investigations finding that recovery of species richness and abundance can occur within one or two decades after the logging event. In this study, we use ant assemblages to compare logged (>30 years) and unlogged mixed dipterocarp forest in the Sinharaja Forest Reserve, a World Heritage Site in Sri Lanka. Species richness and abundance were higher in the logged forest than in the unlogged forest, but not significantly so. Species assemblages, on the other hand, were significantly different and were associated with different environmental variables in the logged and unlogged forest. The findings from this study corroborate other studies that have shown that species composition in logged forest does not appear to return to unlogged forest composition, even after three to six decades have passed.
