Lara Rozzell, M.S.
Alternative Energy Impacts, Riparian Monitoring, Revegetation Methods
Lara Rozzell began monitoring ecological impacts of energy development in 1992, with an emphasis on alternative energy projects. In recent years, she has focused as an independent consultant on offshore and terrestrial wind energy development impacts, and the problems of effective facility siting and ecological monitoring as the world’s energy systems evolve away from fossil fuel use. She is dedicated to learning from the mistakes of past energy development and bringing the best siting, monitoring, and mitigation practices to the emerging wind energy industry.

Lara served on the Board of the Native Plant Society of North Carolina as it faced a period of rapid suburban expansion and habitat loss in the Southeast. Serving also as Extension Faculty in Biological and Agricultural Engineering at North Carolina State University, she worked on a team grappling with the questions of restoration “success” while developing monitoring protocols for stream and wetland restoration projects for North Carolina’s Clean Water Management Trust Fund and Ecosystem Enhancement Program. She trained and led field crews monitoring coastal, Piedmont, and mountain restoration projects, and developed and taught workshops in revegetation and monitoring for diverse groups including biologists, engineers, regulators, and maintenance crews.

Lara received undergraduate training in Biology from Whitman College and the University of Nevada, Reno, and holds an M.S. in Ecology from Utah State University. Her graduate research focused on plant community interactions during recovery after clearcutting in the H.J. Andrews Experimental Forest and post-volcanic plant community development in the Mount St. Helens Volcanic Research Area.

John Randall, PhD
Invasive Species Management
John is Global Invasive Species Team Lead for The Nature Conservancy (TNC). He is based in and has courtesy appointment with the Department of Plant Sciences at the University of California, Davis. He oversees a Team of 9 core members and over 25 affiliates who spearhead TNC’s efforts to prevent new invasions to terrestrial, freshwater and marine habitats at international and national scales, and to build the capacity of TNC’s state and country programs in the USA and 30 other nations to prevent and manage invasive species threats to biodiversity. The Team uses a variety of approaches to achieve these goals including promoting better on-the-ground management, research and advances in state, national and international public policy (public agency policy and actions, legislation, appropriations) as well as engaging industries and coalitions to voluntarily change business practices.

John received a B.A. in Biology from Cornell University in 1982, earned an MS in Marine Science at Louisiana State University in 1986 and completed a Ph.D. in Ecology at the University of California, Davis in 1991.
