JC Raulston Arboretum e-Update

January 2009

In This Issue

New Interim Director

Ted BilderbackTed Bilderback, Ph.D., will begin a new assignment as interim director at the JC Raulston Arboretum the first week of January 2009.  He has been a faculty member in the Department of Horticultural Science for 32 years.  Ted was born in Kansas and was raised in a farming community near Valley Falls.  He received his B.S. and M.S. degrees in biology from Emporia State University, and his Ph.D. in horticulture from Kansas State University.  He also served in the Naval Reserves.  Ted was hired as an assistant professor in the Department of Horticultural Science at NC State in 1977 with research and teaching responsibilities in nursery production.  From 1977 to 1987, he co-taught Nursery Production and Management courses each fall with J. C. Raulston and Tree and Grounds Maintenance spring semesters.  He continued to teach these courses for two years after J. C.’s death in 1996.  In 2003, Ted developed a new graduate level course, Environmental Nursery Production, which is taught on campus and through distance education—one of the first DE courses to be offered by the Department of Horticultural Science.

In 1987, Ted took on responsibilities as the Nursery Extension Specialist for the department.  Since then, he has worked closely with the nursery industry to develop cost effective and environmentally conscious cultural practices for growing nursery stock with emphasis on container substrates, plant and substrate nutrient levels, and irrigation management.  His work has resulted in 51 scientific papers and a total of 535 published articles.  He has also advised 22 graduate students.  Ted serves as the educational advisor to the North Carolina Nursery and Landscape Association, and presents approximately 25 talks a year to nursery audiences in North Carolina and elsewhere. 

Ted has received numerous awards for his work, including the American Association of Nurserymen’s Extension Award, Southern Nurserymen’s Association Porter Henegar Memorial Award for Research, Extension Education Award from the North Carolina Cooperative Extension Service, Environmental Award from the Southern Nursery Association, NC State College of Agriculture and Life Sciences Outstanding Extension Service Award, and the Distinguished Alumni Award of Emporia State University.  In 2000, Ted was initiated as a charter member of the NCSU Academy of Outstanding Faculty Engaged in Extension, and in 2008, elected Fellow of the International Plant Propagators Society Southern Region North America Chapter.

Ted was a longtime colleague and friend of J. C. Raulston and feels a deep affinity for the Arboretum. J. C. and Ted’s students were responsible for planting many of the older specimens in the collections and the older holly borders.  He looks forward to serving as the interim director and offering his knowledge and experience to help the Arboretum advance in its mission.  Ted is married to Linda Bilderback and they have two sons. – Julia Kornegay, Ph.D., Head and Professor, Department of Horticultural Science, NC State University

Wilson was one of the great plant collectors of all time, collecting over 3,300 different types of plants in Asia, including over 900 that were new to science. Take a walk through the JCRA as we look at some of his best introductions.

Friends of the Arboretum Lecture – January 8 (Thursday) – 7:30 PM – Free for members, $5.00 for nonmembers

"Permeable Pavement" presented by Fred Adams, Fred Adams Paving Co. This presentation explains the benefits of using permeable pavements and when and how they can be used in North Carolina. It covers the Permeable Interlocking Concrete Pavers (PICP) as well as new Clay Brick Permeable Pavers and how they are a part of Low Impact Development (LID). The first part of the presentation explains the benefits of permeable pavers and how they reduce storm water run-off and increase ground water recharge. Fred goes through the research performed at NC State University, the history of the acceptance by the North Carolina Division of Water Quality (NCDWQ), and the approval as a Best Management Practice (BMP). Also covered is information about U.S. Green Building Council (USGC) green building rating system Leadership in Energy and Environmental Design (LEED) and how permeable pavements can help contribute points to sustainable projects by reducing storm water, heat island effect, recycled materials, etc. The second half of the presentation goes through the construction process and methods used to build the Permeable Pavement Systems, you will get design ideas and details and specifications. Samples of the pavers will be on hand to touch and feel as well as the different sizes of aggregate used to construct the cross section.

Per Fred Admas, this presentation is approved by the North Carolina American Society of Landscape Architects Licensing Board (NCASLA) and receives a one hour CEU. The presentation also receives continuing education from the American Institute of Architects (AIA) provided through the Interlocking Concrete Pavement Institute (ICPI). It is a generic presentation about permeable pavers and does not favor any one manufacturer it centers on the system itself.

Friends of the Arboretum Lecture – January 22 (Thursday) – 7:30 PM – Free for members, $5.00 for nonmembers

"Well's Natural Gardens: Photos and Prose" presented by Thomas Wentworth, Ph.D., Professor, Department of Plant Biology, NC State University. This presentation focuses on the life and work of pioneer ecologist B.W. Wells, Ph.D. Wells was professor and head of the Department of Botany and Plant Pathology at North Carolina State College (now North Carolina State University) from 1919 to 1949, and he remained on the faculty until his retirement in 1954. Wells was one of the first generation of ecologists in the United States, and he contributed in fundamental ways to our understanding of the ecological conditions and processes responsible for North Carolina's diversity of natural communities. The presentation is illustrated with Wells' own remarkable photographs, four-by-five-inch negatives he converted to glass lantern slides. Many of these black-and white photographs, featuring native plants and natural communities, were hand-tinted by Wells. The presentation also features readings from Wells' popular work, The Natural Gardens of North Carolina, originally published in 1932. The combination of Wells' inimitable writing style and his lovely photographs should be of interest to anyone interested in North Carolina's natural history and native plants.
