Dahle, Gregory

Associate Professor of Forest Resources Management

Greg Dahle teaches undergraduate and graduate courses in arboriculture and urban forest management. Dr. Dahle’s research utilizes allometric modeling and tree biomechanics to understand how urban trees grow and survive environmental loads such as those from snow and ice storms. He has worked as an arborist managing commercial and municipal tree care accounts in the San Francisco Bay Area and served as a consulting utility arborist. He holds a doctorate from Rutgers University, and a Masters and Bachelors of Science from Purdue University. He is an International Society of Arboriculture Board-Certified Master Arborist.
