Anurans (amphibians) have also been identified as potentially valuable indicators of some environmental changes. The small home ranges and relatively limited dispersal ability may render amphibians useful for monitoring the effects of local environmental pertubations. In addition, their moist permeable eggs and skin also make them good 'bioindicators' of environmental stress. Given both the important roles and functions of amphibians in forest ecosystems and the significant impacts of logging on forest ecosystems, an understanding of amphibians in relation to forestry practices is required. Relatively few studies have focused on the impact of logging on amphibians especially in the tropics. Those that have been undertaken have related mainly to temperate regions where the logging is usually clear felling and they have concentrated either on single species or on single genera. Therefore, this study will attempt to address this gap of knowledge about the impacts of selective logging on the abundance of anurans in the rain forests of Kalimantan, Indonesia. The study was undertaken from November 1994 to July 1996 at Camp 92, Central Kalimantan. Three sampling methods were used in this study e.g. pitfall traps, searched quadrats and night riparian transects. The results demonstrate that logging had a significant effects on the abundance of anurans and anuran species composition. Logging had a strong influence on vegetation cover, which in turn affects the temperature and humidity. Logging also affects the physical characteristic of the streams especially the bottom substrates. Logging also affects the physical characteristic of the streams and abundance of anurans. The challenge in research for future researchers of amphibian-forestry relationships is to identify realistic timber harvest prescriptions that best maintain those components of the forest's biological legacy that are essential for healthy amphibian populations and forest ecosystem as a whole.
