Abstract

Within Midwest floodplain forests, there is a lack of long-term studies focusing on native tree recruitment post invasive shrub removal. With interacting threats such as emerald ash borer (Agrilus planipennis), invasive earthworms, and white-tailed deer (Odocoileus virginianus), land managers need particular information about these ecosystems in order to better understand how to protect them. This study aims to explore the efficacy of the removal of Rhamnus cathartica and Lonicera spp. in promoting native tree recruitment within a Minnesota floodplain forest along the Mississippi River. Results revealed that post removal ash (Fraxinus spp.) seedling abundance increased, enhancing recruitment. Additionally, evidence showed moderate deer impacts on overall vegetation community structure.
