Species survival in fragmented landscapes: Where are we now?

We present a brief introduction to current attempts to understand and mitigate the effects of fragmentation on species survival. We provide a short overview of the contributions of empiricists, modellers, and practitioners in this issue of Biodiversity and Conservation, which were initiated during a workshop held in Australia in February 2002 on the topic 'Species Survival in Fragmented Landscapes: Where are we now?'. These contributions address the themes 'uncertainty in research and management', 'tools for quantifying risk and predicting species sensitivity to fragmentation', and 'tools for reassembling fragmented landscapes'. A final contribution provides a synthesis across the contributions and highlights the most important areas for future research on species survival in fragmented landscapes.
