Arborists turn to surgery to save American elms Philadelphia Inquirer 05/08/2009: "Arborists turn to surgery to save American elms
By James M. O'Neill
TENAFLY, N.J. - A chain saw's drone drowned out the trill of migrating warblers in the Greenbrook Sanctuary woods as arborists conducted major surgery to save an extremely aged patient - a 163-year-old American elm tree.
Dutch elm disease has wiped out some of the few remaining stands of native elms in the region.
Greenbrook Sanctuary recently lost four of its 12 remaining elms. That spurred Nancy Slowik, the sanctuary's director and naturalist, to lobby the organization's board to start an aggressive campaign to save the elms that were left."
