Dennis Whigham of SERC (Smithsonian Environmental Research Center) . – Native Orchid Ecology and Conservation
There are more than two hundred native orchids in the U.S. and Canada and approximately 65% of them are in trouble in some part of their range of distribution. The North American Orchid Conservation Center (NAOCC) was established about 10 years ago to develop a network of collaborators to assure the survival of our native orchids.
Whigham obtained an undergraduate degree from Wabash College and a Ph.D. from the University of North Carolina. He joined the Smithsonian in 1977. Whigham and his collaborators have published more than 235 articles in journals and books, and he has co-edited
ten books. The ecology of plants has been Dennis Whigham’s primary interest and his research has resulted in journeys through forests, fields, and wetlands around the world.
