Margaret A. Palmer

Margaret A. Palmer is a Distinguished University Professor in the Department of Entomology at the University of Maryland and director of the National Socio-Environmental Synthesis Center (SESYNC). Palmer works on the restoration of streams and rivers, and is co-author of the book Foundations of Restoration Ecology. Palmer has been an invited speaker in numerous and diverse settings including regional and international forums, science-diplomacy venues (e.g., in North Korea ), and popular outlets such as The Colbert Report.

Education and career Palmer has a B.S. in biology from Emory University (1977), and Ph.D. (1983) in coastal oceanography at the University of South Carolina with a focus on hydrodynamics and dispersal of benthic organisms. Palmer was an assistant professor at Wabash College from 1983 to 1987, Palmer was a program officer in Ecology at the National Science Foundation from 1999 to 2000. From 2005 to 2011, Palmer was the director of the Chesapeake Biological Laboratory at which point she transitioned into her current position as director, National Socio-Environmental Synthesis Center. Her research suggests it is unlikely for a disrupted ecosystem to be restored to original conditions so it is necessary to engineer a productive ecosystem that will serve the needs of the current biological community as well as the growing human population. Palmer also documents the relationship between stream recovery and water quality, finding that recovery is often dependent on removing the source of contamination rather than improving any physical stream structures.

Restoration ecology Palmer conducted multiple research projects in the field of restoration ecology and co-authored the book Foundations of Restoration Ecology. She suggests a more holistic approach that observes the inputs and outputs of the ecosystem and how biodiversity can be increased. The study concluded that the controversial method of resource extraction has irreversible effects on the ecosystem, specifically headwater systems. Palmer documents the change in stream health showing a decrease in species biodiversity, poor water quality, higher stormwater runoff, and high concentrations of contaminants. She has been called as an expert witness to testify before congress on the issue of mountain top mining and joined other scientists in calling for an end to the practice.

Contributions to ecotoxicology Palmer's research extends into the field of ecotoxicology where her research has shown that the addition of physical structures or improvements to habitat complexity is not sufficient for increasing biodiversity when contaminants are still entering the ecosystem. Palmer's research concluded that stressors such as intense storms and the volume of TSS upstream were more likely to affect stream health than increasing stream-wetland complexes. Palmer, M.A., B.
