Board of Directors
SGI currently operates within the framework of Austin Peay State University Foundation, which gives SGI flexibility to function within a 501(c)(3) non-profit capacity. We are currently exploring options for creating a separate foundation within the University. This will involve establishing on our board of directors. Please stay tuned.
Dwayne estes ph.d., executive director
Dwayne Estes serves as executive director for SGI. For ten years Dwayne has served as Professor of Biology at APSU and was promoted to Full Professor in 2015. Since 2008, he has served as a Principal Investigator for APSU’s Center of Excellence for Field Biology. In 2013, Dwayne was awarded tenure and accepted a joint position with BRIT where he serves as Botanical Explorer. In the past several years, he and his collaborators have successfully secured more than $1 million dollars in grants, including three from the National Science Foundation. He has published 20+ publications and has directed the work of more than a dozen graduate students. In May 2016 he organized and hosted the Mid-South Prairie Symposium and has built a strong network of collaborators, from farmers and scientists to corporate business leaders and politicians. Dwayne manages a dedicated team who will work on grassland conservation projects across the Southeast.
Theo Witsell, Director of research
Theo Witsell serves as Director of Research for SGI, gathering and synthesizing data on the ecological and historical significance of southeastern grasslands, advising coordinators, and providing scientific direction and ecological context for the program. Theo has worked as senior botanist and ecologist for the Arkansas Natural Heritage Commission since 2000 and in 2013 was invited to serve as a research associate with BRIT. He publishes regularly and has authored or co-authored more than 30 scientific publications and book chapters, including the description of new species. In addition to his scientific expertise, Theo is intimately familiar with practical on-the-ground management of natural areas and conservation strategies and brings unique expertise in this area.
reed Noss ph.D., chief science advisor
Reed Noss is a world-renowned conservation biologist recently retired from the University of Central Florida. He holds a B.S. in Education from the University of Dayton, an M.S. in Ecology from the University of Tennessee, and a Ph.D. in Wildlife Ecology from the University of Florida. He has served as Editor-in-Chief of Conservation Biology (1993-1997), President of the Society for Conservation Biology (1999-2001). Reed has more than 300 publications and is recognized as one of the 500 most highly cited authors in all fields worldwide. He has published eight books, the most recent being Forgotten Grasslands of the South: Natural History and Conservation (2013, Island Press). In addition to his work with SGI, Reed is currently writing books on the fire ecology of Florida and the lower Southeastern Coastal Plain (University Press of Florida) and on natural disturbance as a primary factor that structures ecosystems (Island Press).
Reed's Recent Book: Forgotten Grasslands of the South
Alan Weakley, is widely regarded as one the leading botanists and plant community ecologists in the eastern U.S. with extensive on-the-ground experience in all Southeastern states. He holds a B.S. degree in botany from the University of North Carolina-Chapel Hill and a Ph.D. in botany from Duke University. He currently serves as Director of the Herbarium at the North Carolina Botanical Garden and adjunct professor at UNC. In his 40-year career, he has served as Senior Regional Ecologist for The Nature Conservancy and Chief Ecologist for NatureServe. He served as Trustee of the N.C. Natural Heritage Trust Fund from 2008-2013 and Chair of the N.C. Plant Conservation Program’s Scientific Advisory Committee. He is the author of Flora of the Southern & Mid-Atlantic States, a botanical manual covering about 7000 plant species, now the standard in use across much of the southeastern U.S., and has been a leader in the development of the U.S. National Vegetation Classification System. Alan brings an extraordinary level of expertise and wisdom to SGI as chairman of the Scientific Advisory Board. He will work with board members in the 21 states of the SGI region to identify and rank projects in need funding and/or urgent conservation action.
Cooper Breeden, Community Ecologist
Cooper is a second-year graduate student in the Department of Biology at Austin Peay State University and a Research Associate for SGI. He is currently studying the effects of canopy-thinning on the flora and ecology of rare calcareous seepage fen communities and the federally-endangered Tennessee Yellow-Eyed Grass (Xyris tennesseensis) in south-central Tennessee.
Mason brock, botanist
Mason is a recent graduate of Austin Peay State University Biology Department's graduate program and currently serves as Collections Manager for the APSU Herbarium, a collection of 120,000 specimens. For his graduate work, Mason documented the flora and plant communities of riparian grasslands, shrublands, and woodlands along the Caney Fork River in east-central Tennessee. He also serves as Research Associate for SGI.
Claire is first-year graduate student in the Biology Department at Austin Peay State University and is a Research Associate for SGI. She is leading efforts to document the highest quality wet grasslands in Tennessee and will soon be working on a project to document riparian grasslands on the Cumberland Plateau. For her thesis, she is studying the flora and community ecology of rare depression ponds that support marsh vegetation and that historically were embedded in open oak savannas.
Zach Irick, Grassland Ecologist
Zach is a second-year graduate student in the Biology Department at Austin Peay State University and is a Research Associate for SGI. He is currently working in northeastern Alabama to document the flora, rare plants, and plant communities associated with the riparian corridor of the Little River at Little River Canyon National Preserve. For his thesis, Zach is conducting a taxonomic study of a group of herbaceous vines of the genus Clematis (leatherflowers), which includes several undescribed species, including a few that are endemic to grassland habitats.
devin rodgers, grassland ecologist
Devin graduated with a master's degree from Austin Peay State University's Biology Department in 2016. He manages a number of projects as a Research Associate for SGI, including the study of high-quality wet grasslands of Tennessee and the description of new species. In January 2018 he accepted a position as an ecologist with the Kentucky Nature Preserves Commission.
Scientific Advisory Board
We will be assembling our Scientific Advisory Board in 2018 who will serve portions of the following states. Stay tuned for an updated list.
