Ph.D - University of Wisconsin-Madison - 1980
M.Sc. - University of Wisconsin-Madison - 1977

Barbara Bedford joined the Department of Natural Resources in 1989,
having served as the Associate Director of Cornell University's
Ecosystems Research Center since 1980. In addition to teaching and
research, she works with conservation organizations and various state
and federal agencies in efforts to solve environmental problems that
affect wetlands and the landscapes in which they occur. Dr. Bedford currently
serves as President of the Society of Wetland Scientists and is the recipient
of the 2005 National Wetlands Award in the Science Research category.
Research
Her research focuses on wetland plant diversity, what controls it,
how human actions affect it, and how to manage it. She and her
students work primarily in fens, bogs, riparian wetlands, and Great
Lakes wetlands. Current projects in her laboratory include:
(a) relationship of groundwater hydrology and chemistry to nutrient
availability, plant productivity, and plant species diversity;
(b) inter-relationships among nutrient availability, plant tissue
chemistry, and plant species diversity; (c) landscape control of
wetland biogeochemistry and hydrology; (d) effects of removing cattails
on fen species composition and diversity; (e) mycorrhizal diversity and
the role of mycorrhizal fungi in maintaining plant species diversity in
phosphorus-poor wetlands; (f) sources of below-ground carbon to riparian
zones and their role in nitrogen dynamics; and (g) development of vegetation
indicators of the state of Great Lakes wetlands.
