John Parrotta is National Research Program Leader for International Science Issues, providing scientific advice to develop U.S. policy positions in international forest policy forums, including the Convention on Biological Diversity and the United Nations Forum on Forests, and other international programs and initiatives related to forest science and sustainable forest management. A significant part of his work is conducted in collaboration with the International Union of Forest Research Organizations (of which the U.S. Forest Service is the largest member). He serves in a number of leadership positions in IUFRO, including Chair of the Collaborative Partnership on Forests’ Global Forest Expert Panel on Biodiversity, Forest Management, and REDD+ (2012), Chair of the IUFRO 2014 World Congress Scientific Committee, Deputy Coordinator of IUFRO Division 8 (Forest Environment), and coordinated the IUFRO Task Force on Traditional Forest Knowledge (2005-2010). John received B.A. and B.S. degrees (in Biology and Chemistry) from Merrimack College in 1980, an M.Sc. in Ecology from the University of Aberdeen (UK) in 1981, and his Ph.D. in tropical forest ecology and silviculture from Yale University in 1987. He is a member of the Society of Ecological Restoration, the Commonwealth Forestry Association, the International Society of Tropical Foresters and the Society of Ethnobotanists, and currently serves on the editorial boards of several professional journals, including Restoration Ecology, International Journal of Biodiversity Science and Management, Pesquisa Florestal Brasileira, and Bois et Forêts des Tropiques. Prior to assuming his current position in the WO in 2000, John held positions as a Research Forester at the Forest Service’s International Institute of Tropical Forestry in Puerto Rico from 1991-2000, and as a research scientist at the University of Puerto Rico from 1987-1990. In these positions, his research focused on tropical forest restoration, ecological dynamics of plantations and other managed forest systems, tropical silviculture, tropical forest floristics and phenology, and non-wood tropical forest products (medicinal plants) in Puerto Rico, Brazil (Amazon and Atlantic forest regions), and India. He is the author of several books, scientific journal volumes, and over 150 other research publications.
