20 THE DAVEY BULLETIN | November/December 2020 In early August, three arborists from Davey's Nanaimo and Victoria Residential/Commercial services offices spent three days completing a level 2 arborist training session at Bowen Park in Nanaimo, British Columbia. Led by Walter McLean, regional safety specialist, The Davey Tree Expert Co. of Canada, Limited, the training is designed to improve arborists' skillsets in three ways: felling, rigging and climbing techniques. Additionally, the group learned strategies to train their coworkers in the field once they return to their office. Far left: Chris Bentham, climber, Victoria office, after completing a face out cut. Daniel Kannimae, climber, and Bradyn Villebrun, groundman, from the Victoria office also completed the training. Right: Daniel Kannimae and Chris Bentham limb walking using the single rope technique. EXPERTISE TRAINING UP A NOTCH IN CANADA A live oak tree from Johns Island, South Carolina, traveled roughly 200 miles to its new home at the Ally Charlotte Center in Charlotte, North Carolina. It took three years of planning before this tree could plant its roots at the corner of Tryon and Stonewall streets. The client contacted Environmental Design, Inc. (EDI), a Davey affiliate, for this 26-story office tower project to incorporate a signature tree in the exterior design of the building. "They ended up selecting two live oaks," said Paul Cox, vice president, Eastern Division, EDI. "One to be their signature tree and the other as a backup in the event something happened with their first choice." In 2019, both trees were root pruned to see which tree would respond the best. Sure enough, the client's first choice live oak thrived. An important The site conditions where the tree was growing proved to be a challenge with the loading process, because the tree was in an off-road area. A giant steel plate had to be inserted beneath the tree to aid in pulling it several hundred feet to an area where the tree could be loaded for transport. LIVE OAK PLANTS NEW ROOTS IN CHARLOTTE aspect to the success of this tree's transplant was the soil composition. The tree was grown in sandy soil. "We had a custom blend of soil made by a local soil company that matched the original conditions," Cox said. "We wanted to make sure the roots would easily grow and not be hindered in heavy clay soils." In October, the 45-foot-tall and 45,000-pound live oak made its journey to Charlotte. The tree traveled on a specialized trailer that tilted the tree horizontally for transportation. Upon arrival, it was met by a 400-ton crane and placed in a large planter. "The challenge was that we really couldn't get any equipment into the area where we planted the tree because of the finished conditions," Cox said. "We had to do a lot of innovative thinking about how we would backfill 120 yards of soil."
