Little's Importance Value of black ash Black ash wetlands occur across the north-central and northeastern US and into Canada and are ecologically, economically, and culturally important on the landscape. Across this distribution black ash wetlands range from small depressional wetlands to large monotype wetland complexes and black ash often exhibits canopy dominance. These wetlands are threatened by the spread of the invasive emerald ash borer (EAB) and their loss will lead to ecological and economic harm as these systems are severely disrupted.

The goal of our research is to evaluate the impact of that disruption to the ecological and geophysical processes of the wetlands in the Upper Peninsula and to identify suitable species for planting at these sites and determine the best planting strategy to active transition and/or restoration through underplanting. In order to extend the scope of our work we are collaborating with a group from the University of Minnesota and the USFS Northern Research Station in Grand Rapids, MN to develop a Great Lakes regional assessment of the impacts of EAB on black ash wetlands and the potential for transition or restoration to maintain these sites as forested wetlands on the landscape.
