    The Extraordinary Development of Arboriculture in Asia


    Throughout the major centers of South Asia, Southeast Asia and China the rapid development of modern arboriculture practices with a heavy focus on tree risk assessment has caused a serious transformation in how trees are managed in the region. The leading centers of development, Hong Kong, Singapore, and Kuala Lumpur, Malaysia have led the way to producing over 1000 certified arborists in much less than a decade, far surpassing the entire total of all of Europe combined. Don Picker who speaks Mandarin, Cantonese, and a minority language and has led a part of this development with training materials, hosting multiple targeted educational events, and providing real work applications based on the highest Best Management Practices of our industry.
             Along with Dr. Bill Fountain of the University of Kentucky, Picker who is the Directing Manager of Asia Tree Preservation, Ltd. and Chairperson for the Institute of Arboriculture Studies-Hong Kong will lay out an eye-opening history of this development and reveal what could become the future of arboriculture as the country of China, with it's population of 1.3billion people develops cities in a frantic pace with a demand for instant mature treed cities. Picker and Fountain will present a clear and fascinating account which will keep people interested and challenged for how the new contract-arborist/educator can become a part of this future. Many cases of arborists applying skills throughout the region will be provided which will peak the interests of the adventurist and widen the perspective of the USA-based practitioner to recognize their part in a much larger world-wide industry where the limits are still unknown and yet to be discovered!
