I am a plant systematist, plant community ecologist, biogeographer, and conservation biologist focused on the species and systems of the Southeastern United States. Students in my lab focus on the systematics and biogeography of the Southeastern United States, community classification developing the U.S. National Vegetation Classification, and land management, conservation planning, and environmental policy questions involving the conservation of Southeastern United States ecosystems and species.
Prior to coming to UNC in 2002, I had an extensive career in applied conservation biology, working with the North Carolina Natural Heritage Program, The Nature Conservancy, and NatureServe (the Association for Biodiversity Information). My conservation interests and activities continue, with my service as Trustee of the N.C. Natural Heritage Trust Fund (http://www.ncnhtf.org/) (which has provided $328 million through 518 grants to support the conservation of more than 298,000 acres of natural areas in North Carolina), Chair of the N.C. Plant Conservation Program’s Scientific Advisory Committee (http://www.ncagr.gov/plantindustry/plant/plantconserve/index.htm), and Chair of the N.C. Natural Heritage Program Advisory Committee (http://www.ncnhp.org/).
I am the author of Flora of the Southern & Mid-Atlantic States (http://www.herbarium.unc.edu/flora.htm), a taxonomic manual covering about 7000 vascular plant taxa, now the standard in use across much of the Southeastern United States. With J. Chris Ludwig and Johnny Townsend, I am co-author of the Flora of Virginia (http://www.floraofvirginia.org/), to be published in 2012, and am also an active author, editor, reviewer, and director of the Flora of North America project (http://fna.huh.harvard.edu/). I was a co-founder of the Carolina Vegetation Survey (http://cvs.bio.unc.edu/), and continue as one of its four organizers.
