Picture Creek Diabase Barrens (PCDB) is a biologically unique area located in the northeastern Piedmont of North Carolina in Granville County. The 407.4-acre site lies within one of North Carolina's Triassic basins, where diabase intrusions have given rise to mafic soils rarely found in the Piedmont. PCDB hosts a remnant Piedmont prairie that boasts a high density of rare plant species. Though several incomplete floristic species lists have been compiled previously for PCDB, very few vouchers exist from the site, and a comprehensive inventory has been lacking. A current and comprehensive assessment of the floristic diversity of PCDB is vital for the development of successful management and conservation strategies. The resulting Guide to the Vascular Flora of Picture Creek Diabase Barrens provides a comprehensive checklist of the flora compiled from the first author's collections, historic collections, and reports of species from the site. The illustrated guide treats 676 species and subspecific taxa (48 of these rare) from 113 plant families. Keys are provided to all vouchered or reported taxa. In addition, the following information is given for each taxon: taxon name and authority, synonymy, common name(s), state and federal status (if applicable), habitat, associated soils, abundance at PCDB, phenology, collections, sources reporting the taxon, and illustrations, if available. This is the third in a series from the Illustrated Floras of North Carolina Project at the North Carolina State University Vascular Plant Herbarium (NCSC), designed to be useful to both botanical specialists and a more general audience.
Jennifer S. Stanley, M.S. is a field botanist from North Carolina with degrees in ecology and plant biology. She has spent the last decade working at state and national parks, field stations, and nature preserves. She is passionate about conservation and habitat restoration, especially when it benefits rare species and natural communities. Jennifer currently works for the North Carolina Plant Conservation Program where she monitors rare plants, conducts prescribed burns, and manages plant conservation preserves across the state for the benefit of rare plants and their habitats. In her free time, she enjoys playing viola, creating art, hiking, and (of course) botanizing.
Alexander Krings, Ph.D., serves as Associate Professor of Plant Biology and Director of the Vascular Plant Herbarium at North Carolina State University. His work focuses on floristics, plant taxonomy, and conservation biology. Dr. Krings has taught courses in field botany for the past decade and recently partnered with Dr. Richard Braham to develop the NCSU Certificate in Field Botany.
Jon M. Stucky, Ph.D., is Professor Emeritus of Plant Biology at North Carolina State University. He has taught undergraduate and graduate level field botany courses for over thirty years, including Systematic Botany, Wetland Flora, Local Flora, and Grasses, Sedges & Rushes. Dr. Stucky’s research focused on rare plant species ecology and conservation.
Richard R. Braham, Ph.D., earned a bachelor’s and master’s degree from the University of Michigan, and a doctorate from North Carolina State University, all in forest management. He is currently a professor of forest management at North Carolina State University where he has taught undergraduate and graduate courses in dendrology, advanced dendrology, forest communities, and forest science for over 40 years. He is author or co-author of three books, all dealing with woody plant taxonomy.
