September/October 2017 | The Davey Bulletin 11 Graeme McMahon, tree-climbing legend from Australia, presenting at RAW. NOTES FIELD The speakers at the 2017 Rochester Arborist Workshop (RAW) focused on the practice and theory of working in compromised trees and encouraged the over 320 attendees, including 40 employees from Davey's four Minnesota R/C offices, to constantly perfect their skills. RAW featured speakers Graeme McMahon, tree-climbing legend from Australia, and Dr. Kevin T. Smith, a U.S. Forest Service scientist who studied under Dr. Alex Shigo, a plant pathologist and longtime scientist for the U.S.F.S. who helped pioneer modern pruning methods. McMahon presented about his work to inspect extremely large trees to COMPROMISED TREES FOCUS OF 2017 ROCHESTER ARBORIST WORKSHOP make sure they were not compromised as a safety precaution for crews, said Ryan Brick, district manager, Maier Tree & Lawn, a Davey company. "For me, I am a little bit more of a tree nerd and I gravitate more toward the science side of things at RAW," Brick said. "It just reminds me of how impressive trees really are and they are these incredible plants that can do so many things." Smith discussed relating the material he and Shigo found in relation to emerald ash borer infested trees and the strength and loss component, Brick said. Smith talked about how to safely work in those trees to serve clients. Brick said RAW has been an outreach program that attracts arborists from all over Minnesota, Southwestern Wisconsin and Northeastern Iowa. When RAW started, the goal was to raise the bar for all people in the arboriculture industry in terms of the quality of the science they were using. Brick said when people come to RAW for the first time you can see the wheels turning in their heads about best practices. Attendees take away a lot from the event. "The excitement the presenters generate seems to feed into people who have been around awhile and they get excited based off that energy," Brick said. "It is a neat atmosphere to be in." Forty employees from Davey's four Minnesota R/C offices attended RAW, the Minnesota Society of Arboriculture's largest educational event. S&S Tree and Horticultural Specialists, a Davey company, was the highest bidder on a Graeme McMahon poster, with all proceeds going to the Minnesota Society of Arboriculture.
