Pascal Berrill
Professor - Silviculture & Restoration
I’m committed to training the next generation of forestry professionals, and filling knowledge gaps to support sustainable management of forest ecosystems. I specialize in: multiaged silviculture, tree growth response to treatment and disturbances, rehabilitation and restoration of degraded forests, climate change adaptation, and carbon forestry (silviculture to maximize biomass production/carbon sequestration), and how variations in the natural environment affect results from these research areas.
Around California, I have partnered with federal and state agencies and the forest industry to establish and maintain large manipulative field experiments with ongoing opportunities for graduate student research:
- Coast redwood multiaged silviculture experiment (Mendocino & Humboldt)
- Douglas-fir/tanoak rehabilitation forestry experiment (Mendocino & Humboldt)
- Aspen restoration study (Lake Tahoe Basin, California & Nevada)
- Coast redwood climate adaptation experiment (Humboldt County)
- Black oak post-fire restoration study (throughout northern California)
- Ph.D. (2008) University of California, Berkeley, Silviculture
- M.S. (2003) University of California, Berkeley, Silviculture
- B.For.Sc. (1999) University of Canterbury, New Zealand, Forestry Science
- FOR 430/530 Advanced Forest Ecosystems
- FOR 431 Forest Restoration
- FOR 432/532 Silviculture
- FOR 479 Forestry Capstone
