At the American Orchid Society's 2025 Spring Members Meeting in Annapolis, Maryland, the AOS Conservation Committee presented NAOCC's Dennis Whigham with the Philip E. Keenan Award, in recognition of his long and distinguished career and numerous contributions to the conservation of native orchids.
Dr. Whigham received his PhD from the University of North Carolina before joining the Smithsonian in 1977. He retired in December 2023, becoming the first recipient of the Smithsonian’s Distinguished Service Career Medal. Over 47 years at the Smithsonian Environmental Research Center (SERC), Dr. Whigham, working alongside various collaborators, contributed to more than 250 peer-reviewed articles and coedited 11 books.
In retirement, Dennis remains actively involved in orchid research and conservation, with a special focus on the work of the North American Orchid Conservation Center (NAOCC), a visionary initiative he founded in 2011. NAOCC is dedicated to conserving native orchids for future generations, utilizing an ecologically-based, collaborative model that brings together public and private organizations.
Dennis’s interests and research in plant ecology have taken him to diverse habitats around the globe. His studies have spanned woodland herbs—including orchids, vines, and wetland species—alongside research on invasive plants and forests in tropical, temperate, and boreal forest zones. His wetland investigations have ranged from examining the role of wetlands for juvenile salmon in Alaska’s headwater streams to addressing the spread and management of invasive wetland species in the Chesapeake Bay and beyond. His long-term research on woodland herbs, particularly orchids, inspired new research pathways and led to continent-wide efforts to preserve native orchids.
Congratulations to Dennis on this well-deserved award! See also the May 2025 Issue of the AOS' Orchids Magazine.
