The selective logging of trees in otherwise intact tropical forests can take a serious toll on the number of animal species living there. Mammals and amphibians are particularly sensitive to the effects of high-intensity logging, according to researchers who conducted a meta-analysis of almost 50 previously published studies from around the world. Selective logging in the tropics is not a new phenomenon, and it will continue to be a common use of the forest. Individually, those previously published studies had presented an inconclusive and sometimes conflicting picture of the consequences of the selective removal of trees from tropical forests. Based on invertebrate surveys, primarily representing butterflies, dung beetles, and ants, Burivalova and her colleagues found further diversity losses with logging. Burivalova calls on logging companies to respect logging intensity thresholds that take biodiversity into account. She and her colleagues say that even forests that are currently under sustainable management may be logged at intensities that are far too high for amphibian or mammalian diversity.
