Vanessa Harriman, Ph.D.

Research Scientist

Answering key research questions, building partnerships, and translating knowledge into conservation delivery programs.

Vanessa Harriman joined IWWR and the National Boreal Program in 2018. Her research focuses on factors limiting wetland-associated bird populations. Most recently, Vanessa helped develop research to understand drivers of population change in harvested species. Objectives of these studies were to assess efficacy of management “levers” for achieving conservation, measure effects of industrial activities, and evaluate effectiveness of mitigation efforts. In addition to filling key knowledge gaps for DUC, Vanessa will assist the boreal program in growing and adapting conservation programs based on science. During her master’s program Vanessa was a recipient of the Ducks Unlimited Edward D. and Sally M. Futch Fellowship.
