9 May/June 2019 | THE DAVEY BULLETIN EXPERTISE SAYING GOODBYE TO A BIG POPLAR The Arborguard-Charlotte office removed a 250-year-old eastern yellow poplar tree that suffered root damage at the Historic Duke Mansion. The removal of the tree was a challenge because the tree was located between the street and the mansion, Barry Gemberling, district manager, Arborguard Charlotte, said. There also were shrubs and gardens beneath the tree and powerlines nearby. A crane assisted with the removal. "We probably could have preserved the tree for another couple of years because we were doing annual Resistograph ® testing on the tree," Gemberling said. "But the Lynnwood Foundation, which operates the mansion grounds, was not comfortable with keeping a tree that wasn't healthy where they were having wedding receptions." Prior to Arborguard's care of the poplar, the tree had been in need of restorative care, Gemberling said. The tree received numerous services, including soil injection therapy, soil compaction reduction, risk assessment using the Resistograph ® , pest management, disease management, pruning when needed, cabling, bracing and lightning protection. "We did everything we could to maintain and preserve it; but ultimately the owner of this tree was not comfortable with any risk considering the constant activities under its canopy and on its critical root zone areas," Gemberling said. Chris Wermter, foreman, standing inside the stump of the eastern yellow poplar Arborguard removed. As Barry Gemberling said, even though the tree had a hollow spot, it still had adequate sound wood thickness, which means the tree could still transport nutrients from the roots to the canopy. This was determined from the annual Resistograph ® testing. It's not uncommon for a tree to stay alive even though the center is hollow and rotted out.
