You must be a certified Weed Warrior through Montgomery Parks or working under the supervision of a certified Weed Warrior to remove invasive species from City of Rockville parks. Important Note: The Montgomery Parks Weed Warrior training and certification requires that you commit to removing invasive species in Montgomery Parks, not just the City of Rockville.

You must be physically able to move through wooded and open space areas pulling out invasive species.

If you are a certified Weed Warrior interested in working individually to remove non-native invasive plants from a Rockville park, please email Shannon Philbin at with the details of your request including a map of the park/locations you wish to work in, name of the species you plan to target, and the dates and/or frequency you would like to work.
