Why remove ivy?
English and Irish Ivy grows out of control in our local ecosystems. Since it is not native to this area, it didn't evolve with wildlife that eats it or parasites that destroy it, and it survives through our relatively mild winters just fine. These ivies are a popular, fast-growing garden and landscaping plant, and birds love its tasty berries. For these reasons, ivy has been able to gain a strong foothold in our natural areas around Portland. English and Irish ivy are able to grow in dense carpets across the forest floor, taking resources from native plants that support wildlife. Invasively growing ivy also climbs trees, adding weight that can cause them to topple during storms. Invasively growing ivy has shallow roots that do a poor job of holding in soil, and this creates conditions for increased erosion that cloud our waterways and warm our streams and rivers so that aquatic species struggle or disappear. By removing ivy and planting native species, we give our native plants and our wildlife a fighting chance to survive and thrive in our beautiful and unique urban natural areas.
