Dennis Whigham, PhD
Dennis Whigham is Senior Botanist, Smithsonian Environmental Research Center and Founding Director, North American Orchid Conservation Center. His research in plant ecology has led him around the world through forests, fields and wetlands. He has focused on studying woodland herbs, including orchids, vines, wetland species, and invasive species, and on forests in tropical, temperate and boreal zones. Dennis currently researches the rarest terrestrial orchid in eastern North America; the role of wetlands associated with juvenile salmon habitat in Alaska headwater streams; and an invasive wetland species expanding rapidly across the country.
In recent years, his studies of interactions between orchids and fungi have led in new and exciting directions, including establishing the North American Orchid Conservation Center (NAOCC), an initiative of the Smithsonian and the United States Botanic Garden. NAOCC’s mission is to secure the genetic diversity of native orchids for future generations using a model for orchid conservation based on public-private collaborations. There are currently more than fifty collaborating organizations distributed across the U.S. from Florida to Alaska.
Dennis obtained an undergraduate degree from Wabash College and a PhD from the University of North Carolina. He joined the Smithsonian in 1977. Dennis has co-edited 10 books and, along with collaborators, published more than 250 articles. Dennis serves on TNFW’s Board of Directors.

Catherine Hulshof, PhD
Catherine Hulshof is an Assistant Professor in the Department of Biology at Virginia Commonwealth University. She is the Principal Investigator of the Biodiversity Research Lab which combines observational, experimental, and theoretical models to understand patterns of biodiversity across space and time. Catherine and her students use phylogenetic and trait-based approaches to explain variation in the diversity of plants and Lepidoptera (moths and butterflies). Using large datasets that document long-term forest dynamics, her research is conducted in temperate and tropical forests and across latitudinal, elevational, and edaphic gradients. She holds a BA in Biology and Chemistry from the University of Pennsylvania and a PhD in Ecology and Evolutionary Biology from the University of Arizona.
