Landscape change and the science of biodiversity conservation in tropical forests: A view from the temperate world

Using a largely temperate forest perspective, this article briefly reviews four often inter-related types of landscape change which can have significant impacts on tropical and temperate forest biodiversity: logging, fire, forest clearing, and plantation expansion. There are many important similarities but also key differences in the kinds of work conducted on these four kinds of landscape change in tropical and temperate forests. For example, direct studies of the effects of forest conversion on biodiversity are relatively rare in both tropical and temperate ecosystems. Temperate forest research differs from tropical research in terms of relative amount of single species work, long-term studies, and research at scales spanning multiple landscapes. There are key areas for cross-fertilization of research in tropical and temperate forest biomes. These include: (1) the ability of species to persist in post-disturbed forest landscapes, including those perturbed by past clearing, logging or wildfire, (2) the impacts of plantation establishment on biodiversity, (3) the effectiveness of altered silvicultural systems on forest structure, vegetation composition, and biota, and (4) inter-relationships between forest logging and fire-proneness. Cross-learning about the impacts of drivers of landscape change between tropical and temperate forests is fundamental for speeding the progress of conservation efforts in both broad kinds of environments. However, some opportunities for cross-learning have not been taken because temperate and tropical forest research has often sometimes been isolated from one another. Some approaches to tackle this problem are briefly outlined.
