Abstract

Black ash (Fraxinus nigra) swamps represent 4.5% of the forested area in the western Great Lakes region (Michigan, Minnesota, Wisconsin). Within the swamp hardwood cover type, black ash comprises 40% to almost 100% of the canopy cover and acts as a foundational species, impacting hydrologic regime, nutrient cycling, and wildlife habitat. The dominance of black ash in these stands makes them particularly vulnerable to the invasive emerald ash borer (EAB) (Agrilus planipennis Fairmaire) (Coleoptera: Buprestidae). EAB infestation can result in a mortality rate of up to 99% for ash species within 5 to 7 years. Due to the threat EAB invasion poses to the structure and function of black ash forests, research is being conducted to determine adaptation strategies for managers. One such strategy is to increase tree species diversity through artificial regeneration (from planting). However, there is limited information available on how potential replacement tree species respond to flooding and available light (shade).
