Arborist Demonstrates State-of-the-Art Tree Care Technology at Hawthorne Elementary School's First Science Fair
New York, NY May 1, 2007Hawthorne Elementary School held its inaugural Science and Technology Fair today. Twelve volunteers from the Pleasantville NY, Rye NY, Port Chester NY, Scarsdale NY and White Plains NY area represented a variety of professions including arborist, police detective, structural engineer, chemist, and pharmacist. Joan Skloot, a faculty member who helped organized the event said, “Our goal was to introduce and enlighten our students to some of the many careers that use science and technology in today’s work force.” Each presenter gave an interactive demonstration to Hawthorne’s second grade class, and had prizes for the children to take home and share with their families.
ISA Certified Arborist Chad Otrosinka a tree expert with experience in Hawthorne NY, Mount Pleasant NY, and all other areas of Northern Westchester County NY, represented the arborist profession and demonstrated the resistograph. The resistograph is a valuable tool used to identify at-risk tree conditions.
Through resistograph technology, an arborist is able to detect potentially dangerous wood decay, stages of rot, hollow areas, cracks and ring structure. The instrument measures resistance while drilling a small hole into the tree trunk. It uses a constant velocity probe, a drilling needle with a diameter of 1.5 mm to 3.0 mm, to test structural wood quality. As the drill enters the tree, the resistance of the wood changes the rotation speed of the drill. These variations are translated into a graph, which resembles an EKG printout.
“I brought a section of a trunk inside and put it on the table and took my reading from there. When the resistograph “flat lined” on a normal looking trunk, I turned the log sideways showing the children that it was actually hollow; implying decay within the tree. The kids really latched onto it. They got a really good feel for how the instrument works in the field. Prior to its existence it was difficult to tell if a healthy looking tree on the outside could be dying on the inside. I think that overall the children were really thrown back by the way it works and how neat it is.”
