Biography

The Harapan Rainforest (Hutan Harapan) represents more than 20 per cent of the remaining lowland forest in Sumatra but is in a degraded condition due to historic exploitative timber extraction and under threat from illegal oil palm expansion. This is a significant land management problem. The silvicultural techniques necessary to restore the forest, while realising the commercial and natural capital of the land are not well understood. My work is focused on finding cost-effective, research-driven solutions to direct management. Primarily this involves the establishment of large scale silvicultural experiments, optimising survey techniques (both traditional and remote sensing) and modelling species distributions. I support the research at Harapan, through coordination with the department manager Elva Gemita and her staff. In addition, I work closely with a wide group of visiting researchers, collaborators and government officials. I am an experienced tropical forest researcher with a strong statistical and data management background. A large part of my work involves training Harapan staff in these skills and ensuring the use of optimised sampling/experimental designs.
