Which types of weeds have bark?

Nuisance shrubs, trees and woody vines are weeds that have bark. Bark is what covers the outermost layers of roots and stems in woody plants. Woody plants include shrubs, trees and woody vines.

Weeds are plants that grow where they aren't wanted, that cause harm to the environment, or that have no known usefulness. Thus, woody vines, trees and shrubs are considered bark-covered weeds when they're unwanted in their locations, when they seem to serve no known purpose, or when they cause harm.
