The series is named in honor of Dr. Douglas Worsham. Dr. Worsham had a distinguished career in weed science at North Carolina State University for many years. He had a positive influence on many students at both undergraduate and graduate levels. Dr. Worsham also served many groups in North Carolina as well as groups at national and international levels through his generosity in sharing his knowledge and expertise in weed science. Dr. Worsham has long been considered a unifying figure among weed scientists at North Carolina State University.

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.
