He is currently researching the development of approaches for integrated forest management and nature and biodiversity conservation. His current major research projects include: modelling of wildlife; examining the effectiveness of wildlife corridors; identifying long-term viable populations of organisms; and determining the impacts of habitat fragmentation on forest-dependent and woodland-dependent fauna. In addition, he studies the impacts of habitat fragmentation, large-scale landscape change and wildlife response, and plantation design for biodiversity conservation. He has published 16 books and over 405 scientific articles from his major large-scale and long-term research projects.
