Weed Warriors

Most natural communities support a great variety of native plants and animals.  Such biodiversity is threatened when non-native plants are introduced, spread and dominate an environment, harming native ecosystems, including our streams and trees.

Here are two ways you can get involved:


Become a Certified Weed Warrior Volunteer

In the past, FoCJC sponsored Weed Warrior training sessions in Cabin John.  Participants were trained in identifying and removing vines and plants considered invasive, alien, and destructive.  Trainees received a certification that allows and encourages them to identify, remove, and control these weeds on their own.  We no longer offer our own training events, but if you are interested in becoming a Weed Warrior, you may want to find out more about the Montgomery Parks Weed Warriors program.

To become certified, you must be 16 or older and complete a 2-part online course, attend a 2-hour classroom training, and participate in a 2-hour field training with park staff.  Once you finish the training process, you’ll be authorized to work anywhere on Montgomery Parks, M-NCPPC property on your own schedule and at your own pace. 

Join a Group Workday


Want to help, but not sure you’re ready to become a Certified Weed Warrior?  FoCJC runs Weed Warrior workdays throughout the year — no advanced training required.  These workdays are led by a specially trained volunteer Weed Warrior Supervisor and are a great way to start learning how to identify and remove invasive plants!
