About the project

English ivy is an invasive vine that climbs and smothers trees. Its weight makes trees more likely to fall, it hides decay and pests, and over time it can kill even large, healthy trees.

The Baltimore Ivy Project is a community map of trees that are being overtaken by ivy. Volunteers report trees, and we work with property owners to get permission to cut the ivy at the base — a small action that lets a tree recover.

How it works

• Anyone can browse the map of open and resolved trees.
• Approved contributors add trees by photographing them.
• We mail property owners a friendly flyer with a QR code so they can give permission online.
• Once the ivy is removed, the tree is marked resolved.
