Native alternatives to Invasive Species
English Ivy (Hedera helix)
English Ivy was introduced to the North American continent by European colonists as early as 1727. It’s an aggressive species that threatens all vegetation levels forest from ground into the forest canopy. Birds spread the seeds by eating the fruits. It out crowds native vegetation and is one of the few invasive plants that can thrive in deep shade.
This vine is commonly seen climbing onto trees and these infested trees will decline for several years before they die because when English ivy reaches the upper canopy, it shades the leaves of the host tree, denying the tree the sunlight it needs for growth and nourishment The added weight of the ivy also makes trees susceptible to blowing over during storms. English ivy has been confirmed as a reservoir for bacterial leaf scorch that affects a wide variety of native and ornamental trees such as elms, oaks and maples.
