November 18-20, 2013
Keynote Educator – Dr. Tom Smiley

organised by the Institute of Arboriculture Studies (Hong Kong)

tom_smileyDr. E. Thomas Smiley
IASHK 2013 Keynote Educator

Dr. Tom Smiley is an arboricultural researcher at the Bartlett Tree Research Laboratory in Charlotte, NC and an adjunct  professor of Urban Forestry at Clemson University. His research has assisted the development of: the ANSI A300 Standards and ISA Best Management Practices, strategies for increasing the longevity of side-walks near trees, protocols for tree risk assessment, methods for increasing the effectiveness of lightning protection systems while lowering installation costs, developing the patented Root Invigoration™ method of reducing soil compaction under trees, and pioneering the Prescription Fertilization method.

Dr. Smiley’s work continues to focus on plant growth regulators, the effects of root cutting on tree stability and developing more efficient and effective tree propping systems.

Dr. Smiley was the recipient of the 2012 award for Excellence in Arboriculture Education.

Mark_DMark Duntemann

is a consulting arborist with twenty-five years of experience in urban forestry. He has provided expert testimony in over forty tree-related cases. He specializes in tree forensics, tree value appraisal and operational and management policies associated with tree-related fatalities, personal injuries and property damage. Through his company, Natural Path Forestry LLC, Mark has specialized in tree inventories for multiple Chicago suburbs and other municipalities creating useful documentation of thousands of trees for effective management.

He provides services to an international client base in such areas as Europe, South America among many places and speaks regularly on tree risk topics including program management. He serves on numerous professional Boards and provides peer review on tree failure and related topics for articles, manuals, guides and publications. Mr. Duntemann is an ISA Board-Certified Master Arborist.

elizabeth_brantley04fafbDr. Elizabeth Brantley

teaches forestry, plant biology, and wildlife at Penn State Mont Alto. Her favorite course to teach is Dendrology. She is currently involved in a multi-state butternut (Juglans cinerea) research project. Butternuts are on the decline due to the butternut canker fungus, and losses greater than 70 percent in the forests are estimated. The goal of this project is to identify genotypes that are resistant to butternut canker. Not all trees that look like butternuts actually are butternuts, Dr. Brantley notes. Hybridization with heartnut is common, and these trees often show resistance to butternut canker.  Elabeth holds a Ph.D. in Plant Pathology, an M.F. in Forest Resource Management with an emphasis in Forest Pathology, and a B.S. in Biology with a minor in Chemistry and Psychology.

alexia_stokesDr. Alexia Stokes

received her PhD from the University of York UK in 1994. In collaboration with the Forestry Commission in Edinburgh, she studied the growth responses of young trees subjected to wind loading. Alexia’s particular interest was to understand how tree growth and architecture adapts to mechanical stresses, with a special focus on the root system. After post-doctoral study in Germany, examining root wood strength, Alexia began work at INRA, Bordeaux, France. Working principally on Maritime pine, Alexia and colleagues investigated tree root anchorage with regard to wind storms. In 2005, Alexia began work in China for 2 years, studying how vegetation (plant root systems) could be used to fix soil on slopes against landslides and erosion. She is now based at INRA, Montpellier, France and continues her work on tree mechanics and slope stability in the French Alps and southern China. Recent interests include the ecophysiology of tree root growth at high altitudes and in winter, as well as an understanding of global patterns in root functional traits.

fountainDr. William Fountain

I joined the faculty in the Department of Horticulture of the University of Kentucky  in July 1979 and am currently professor of Arboriculture with an Extension appointment.

My Extension work centers around the arboricultural and landscape maintenance industries. I am actively involved in training arborists for the International Society of Arboriculture certification exam, working with the Kentucky Chapter of ISA (a.k.a. Kentucky Arborists’ Association) ( to provide educational programs on identification & selection, installation and maintenance, tree risk assessment and mitigation of problems. I work with county Extension agents in training Master Gardeners, identification of plants, and identification of cultural and pest problems in their counties.

I have served on the board of directors and currently server as chair of the Council of Representatives for the International Society of Arboriculture ( and and the Kentucky chapter of ISA. I have enjoyed traveling extensively overseas preparing arborists in other countries for the ISA certification exam while learning new techniques and practices beneficial here.

Dr. Bill also presently serves as the Chair of the Board of Advisors for the Institutue of Arboriculture Studies Hong Kong.

The International Arboriculture Summit-Hong Kong 際樹木會議-香港 (IAS-HK) is the annual conference in which well known educators from around the world provide arboriculture related seminars each year at November in Hong Kong. From the beginning in 2008, the summit has included world-renowned arboriculture professors and professionals from the United Kingdom, Germany, Holland, France, Italy, the USA, and Hong Kong. Between 130-170 individuals from Malaysia, Singapore, Macau, China, and Hong Kong have been in attendance each year as the summit event has grown in popularity.

The value it offers in exposure to you as a company or individual consultant in the tree care industry is significant:

·      Receive recognition from entire international arboriculture community (the ISA & multiple chapters, etc.)
·      Local and regional companies, educational institutions & businesses who regularly hire services will         view your name as a participant (multiple mailings go to over 1500 such as the above)
·      Local and regional government agencies are represented each year as they send management representatives to attend the summit and learn the correct practices in line with the industry
