CAR2015 Replace Dead, Dying and Deteriorating Ash Trees

The National Park Service is considering a strategy for addressing the impact of the emerald ash borer (Agrilus planipennis Fairmaire) (EAB) on the historic designed landscape at the Jefferson National Expansion Memorial ("Memorial" or "Memorial grounds"). Part of this strategy will include identifying an appropriate tree species for replacing the Rosehill ash (Fraxinus americana 'Rosehill') and assessing the impacts of replacing the ash trees in the historic planting along the walks (allées) with a different species that will be in keeping with this significant designed landscape. The goals of the project include maintaining the integrity of the National Historic Landmark (NHL), retaining the character-defining features of the Memorial (including the single species tree planting along the allées), minimizing the impact on National Park Service operations, and maintaining and enhancing the visitor experience. The primary goal of the tree replacement is to maintain the significant character-defining qualities of the planting as they contribute to the Memorial's status as a National Historic Landmark.
