Profile

Dr. Patrick Hiesl is forestry professional by heart. He has earned his scientific degrees in Germany and the USA, and has deepened his skills in forest inventory and private woodlot management in Alberta, Canada. Following his graduate studies he has worked in academia as an assistant and associate professor of Forest Operations at Paul Smith's College in New York and Clemson University in South Carolina. He has several years of experience working with logging contractors to conduct time and motion studies on selected harvesting equipment, assess best management practices implementation, and evaluate overall harvesting costs. In addition to research, he has taught several courses in forest operations and wood procurement, but also conducted extension training programs surrounding the use of chainsaws and portable sawmills. Dr. Hiesl has published over 30 articles in various journals and presented his research results at conferences and logging contractor workshops across the USA and Canada. He currently is a South Carolina Registered Forester, SAF Certified Forester, drone pilot, and an active member of the Council on Forest Engineering and the Society of American Foresters.

Research Interests

Dr. Hiesl's research interests are in forest operations and forest engineering with a focus on better understanding the cost and productivity of harvesting operations on small and large forest areas, as well as the use of modern technology to help with forest management activities. He currently conducts research involving horse logging and small-scale equipment, the use of consumer-based LiDAR technology in forestry, logging business surveys to better understand the needs and challenges of logging businesses, mental workload evaluations of logging operations, and the costs and productivity of implementing Climate Smart Forestry practices. Dr. Hiesl collaborates with several faculty within Clemson University and the Department of Forestry and Environmental Conservations as well as the University of Georgia.

Extension and Outreach

Dr. Hiesl is passionate about Extension and educating private forest owners to better manage their forest land. He has been involved in several Extension training programs speaking about forest operations and wood procurement. He most recently started a chainsaw safety training program for female forest owners as part of the Women Owning Woodlands program in South Carolina that has expanded to also include a mixed-gender training program. Dr. Hiesl is a presenter within the Master Tree Farmer program and currently is working on an online training program for beginning forest owners. He also operates a portable sawmill in collaboration with the Clemson Experimental Forest and is in the process of establishing a training program. He frequently collaborates with Extension agents and specialists within the Forest and Natural Resources Program team.
