The density and abundance of English Ivy on the ground prevents other plants and trees from growing up and out of the ivy.
Our team has identified English Ivy as a primary cause for forest decline and reduced forest regeneration in Port Angeles, Port Townsend, Olympia and Poulsbo. English Ivy poses long-term threats to steep slope stability, soil loss, erosion, and forest regeneration. We treat English Ivy in the winter when nearby plants are dormant in order to reduce herbicide damage. We use a combination of both mechanical removal, either by hand or by machine, and a special chemical herbicide formula which can break through vines and thick waxy leaves.
English Ivy is most detrimental on shorelines, steep slopes, riparian slopes, and hillsides.
