Proactive Management of Aquatic Weeds in New Zealand

Dr. Paul Champion
Program Leader – Freshwater Biosecurity & Principal Scientist – Freshwater Ecology

Dr. Champion has specialist expertise in biosecurity, plant ecology and conservation of endangered plant species, especially in freshwater and wetland habitats. Focus research areas include assessment of weed potential of introduced plants, management of alien aquatic weeds (including surveillance, control techniques and strategies), assessment of environmental impacts of both freshwater pest invasions and weed control strategies and restoration of habitats impacted by invasive weeds. In addition to his research areas, Dr. Champion has effectively communicated his and others research in the development of policy and management directions with central and regional government agencies and other resource managers. Examples include providing the science behind national pest management strategies such as the National Pest Plant Accord and National Interest Pest Responses, and regional pest management plans and regionwide lake protection strategies. Dr. Champion has organized consortia of management agencies in order to introduce new control tools into New Zealand and ensured their usage complies with
Environmental Protection Authority standards. Dr. Champion is passionate about training and regularly runs workshops for various management agencies and scientists alike; on plant identification and management, also producing a series of three books on weed identification with the NZ Plant Protection Society. Dr. Champion joined NIWA in 1994 and was appointed Program Leader – Freshwater Biosecurity in July 2015. He has been a Principal Scientist – Freshwater Ecology since 2004. He previously worked with the Ministry of Agriculture and Forestry coordinating eradication programs for nationally important weeds.

The Policies and Politics of Weed Science: Current and Future Outlook

Dr. Lee Van Wychen
Science Policy Director
National and Regional Weed Science Societies

Dr. Lee Van Wychen grew up on a dairy farm near Green Bay, WI. He has a B.S. in Agronomy and Horticulture (1996) and a M.S. in Weed Science (1998) from the University of Wisconsin. After his Ph.D. in Weed Science (2002) from Montana State University, he was selected as the 2003 ASA-CSSA-SSSA Congressional Science Fellow and worked for two members of Congress on agricultural and environmental policy. Since 2005, he has served as Director of Science Policy for the National and Regional Weed Science Societies. His main responsibilities include working with Congress, federal agencies and other NGO’s to promote the research, education, and awareness of weeds in managed and natural ecosystems.

Developing and Maintaining a Sustainable Tool Box to Manage Weeds

Dr. Stanley Culpepper,
University of Georgia

Dr. Stanley Culpepper received his BS degree from North Carolina State University and completed both MS and PhD degree programs at the same institution in Crop Science under the direction of Dr. Alan York in 1999. He is currently a Professor in the Department of Crop and Soil Sciences at the University of Georgia with research and extension responsibilities associated with weed management in a variety of crops. Dr. Culpeper’s contributions to management of herbicide-resistant weeds in cotton and other crops and development of alternatives to methyl bromide in vegetable production have been recognized at many levels worldwide.
