Pascal Berrill – Assistant Professor Silviculture & Ecophysiology
Personal and Research Interests:
My teaching and interdisciplinary research plans focus on silviculture, ecology, physiology, and the linkages between these disciplines i.e., how can we use/expand our understanding of physiological processes and linkages between the growth of a forest and its environment to better manage forest ecosystems. Key areas of research interest include: multiaged silviculture, tree response to stress/climate change, forest restoration, carbon forestry (silviculture to maximize biomass production/carbon sequestration), and how variations in the natural environment affect results from these research areas.
My professional background is in commercial silvicultural research, growth and yield modeling, and intensive plantation management – establishment, pruning, and thinning practices to maximize value. Academic research background includes multiaged management of coast redwood, leaf area index and growth efficiency modeling, geostatistics and spatial pattern analysis, multivariate analysis methods, and linkages between coast redwood ecology, productivity, regeneration, and stand structure.
