Mist-blowing from a tower was used toinvestigate the beetle species richness, abundance and composition at three different canopylevels in a regenerating native forest and a forest plantation of Acacia mangium. Speciesrichness and abundance did not differ between levels in the forest but their numbersdecreased from bottom to top level in the forest plantation. CCA (canonical correspondenceanalysis) showed that there was a distinct difference in species composition between sitesbut not between canopy levels. The study also provided some general information on thecanopy Coleoptera assemblages in the forest and forest plantation: Chrysomelidae andCurculionidae were highly abundant in the forest while in the forest plantation,Tenebrionidae and Elateridae were the most abundant families. Overall, vertical stratificationof the fauna was less pronounced here than in other published studies
