Scientists from the Forest Service along with researchers from USDA Animal Plant and Health Inspection Service and Miami University used a network of long-term monitoring plots in Ohio in a suite of studies to understand the cascading effects of emerald ash borer (EAB) on forest ecosystems. They worked to study how EAB impacts forests, including ecosystems in urban metro parks. When EAB killed almost all of the mature ash trees in these Ohio forests, both native trees and invasive plants responded with increased growth. Maple trees, in particular, were poised to grow rapidly to fill in gaps as the ash trees died; however, even the rapid growth of the remaining tree species was not enough to compensate for the loss in carbon uptake when the ash trees died, and the invasive shrub Amur honeysuckle also grew faster as EAB killed the ash trees. The dead ash trees began to break up and fall, causing a pulse of coarse woody debris on the forest floor. Urban and rural forest managers are using the results of this research in planning their response to EAB.
