Baltimore City Weed Warriors is a city-wide program developed to maintain the health of Baltimore’s urban forest. Certified Weed Warriors are environmental stewards trained in non-native invasive (NNI) plant management for enhancing native ecosystems; they participate in citizen science and host stewardship events in parks all around the city to help protect natural areas, people, and biodiversity.

​

Certified Weed Warriors are volunteers and advocates permitted to work in City Parks and remove NNI plants without the supervision of park employees. To become certified, volunteers complete a [free] 4-part class series and participate in one group NNI plant removal event. The class curriculum includes: NNI plant identification (e.g. English Ivy, Porcelainberry, Kudzu, & more), NNI impacts on Baltimore’s urban ecosystem, removal methods, and leadership training.

​

After completing all requirements, participants become Certified Weed Warriors and receive: a certification card, Weed Warriors t-shirt, NNI plant identification guide, and curriculum resources. The training is free and open to any individual interested in learning more about the importance of nature and biodiversity in Baltimore City.
