We ask questions that bridge ecology and management, incorporating both biophysical and human elements. The common thread linking our areas of study is silviculture, the applied ecology of forest systems. Members of the lab work around the world, in tropical, temperate and boreal biomes. Through fieldwork, laboratory analysis and theoretical approaches, we seek to advance understanding of the relationships between vegetation, biophysical processes and human value systems.
