Abstract: The aim of my study was to analyze the impact of selective logging on plant and bird diversity in East Kalimantan. The impact of logging on plant communities was studied in a forest (in the process of FSC certification) that has been logged selectively 1, 5 and 10 years previously compared to a primary forest site. The stem densities of trees in the primary forest were significantly higher compared to the three selectively logged forest sites. Stem densities of saplings were equivalent in all four forest sites. Seedling stem densities were significantly higher in the forest site logged 10 years previously compared to the primary forest. The “heavy hardwood” class, represented by a certain abundance of stems and species richness, was significantly lower in the forest sites selectively logged 1 and 5 years ago compared to the primary forest site. Stems with a higher abundance in the selectively logged forest sites generally belonged to the “light wood” class. I also studied the impact of logging on bird communities in East Kalimantan. My study compared secondary forest sites with relatively undisturbed primary lowland dipterocarp rain forest sites of East Kalimantan. All birds were identified during point counts in all sites; in the selective logging concession in a primary site and in selectively logged forest sites in the Berau district, a primary site in Sungai Wain and a disturbed site in Pusrehut Kutai Kartanegara. I found a significantly higher abundance of birds in the terrestrial foraging layer in primary forests as compared to secondary forests. I also found a significantly higher abundance of birds of the frugivorous/insectivorous guild and of endemic insectivorous birds in the primary forest.
