Removal of invasive weeds

English Ivy - Toby Query

Aggressive and noxious weeds threaten the health of our natural areas. Where natural habitats are intact, a diversity of native plants filters water, cleans the air, reduces soil erosion and provides habitat for wild animals. The Backyard Habitat Certification Program will help you learn to identify and remove the most damaging plant species.
