2023 Masters Series: Decay-Testing, Biology, Bio-Mechanics

How compromised is a tree with fruiting bodies (mushrooms, conks), cavities, and other indicators of decay? In this workshop, Chris Luley, Ph.D. (President, Urban Forest Diagnostics, LLC) discusses fungal identification, biology and life cycles. He also explains how different decay organisms interact with their host. Frank Rinn, inventor of the RESISTOGRAPH and ARBOTOM (Owner, RINNTECH) discusses tree biology and biomechanics, and how breaking forces act on trees in various states of decay. They will demonstrate the most advanced technology and the most basic methods available for decay assessment. The information provided by these experts will assist you in managing trees with decay more effectively.

Speakers

Dr. Luley has been providing urban forestry consulting services throughout his 40+ year career in urban forestry, pathology, and arboriculture. His degrees are from SUNY Environmental Science and Forestry (BS-Botany) (MS-Forest Pathology) and Iowa State University. He managed the Plant Diagnostic Clinic for Iowa State for four years and was the State Forest Pathologist for the Missouri Department of Conservation before returning to New York.

Dr. Luley has over 70 technical research and popular press articles in publication and four books in press. He recently created treerot.com to help arborists identify the common wood decay fungi on living trees. He received the R. W. Harris Author's Award from the International Society of Arboriculture in 2015, the Brian Skinner Lifetime Achievement Award in 2022 from New York State Arborists, and the Author’s Award from Midwest Chapter of ISA in 2023.

Frank Rinn, inventor of the RESISTOGRAPH® and ARBOTOM® is world famous as an instructor on tree inspection and can help to make you a more expert arborist. Frank owns RINNTECH, a company that develops equipment for dendrochronology, tree and timber inspection since 1988.

Frank invented and developed different methods, machines, and computer programs for various applications in tree-ring analysis, dendrochronology, tree, and timber inspection, such as resistance drilling, sonic tree tomography & root-plate detection, as well as wood surface density analysis. He was granted several national and international patents and trademarks such as on high resolution and high-precision resistance drilling (RESISTOGRAPH®) and sonic tomography (ARBOTOM®). For his inventions and developments, he received several research and innovation awards (1989, 1992, 1997, 1998, 2004, and 2012). Besides managing RINNTECH (manufacturing, selling, and training), Frank also works as a court registered expert, inspecting trees and timber (structures). In addition, he lectures and has published several dozen papers on various topics.

Since 2001, he serves as voluntary Executive Director of ISA Germany and is on the ISA Tree-Risk Panel of Experts and contributes to the corresponding BMP. From 2011 to 2013 he served on the ISA Board of Directors.
