Sarah Morse leading a group of weed warriors along the Capital Crescent Trail in Bethesda. Sarah has been leading monthly workdays along the trail since December 2022 in partnership with the Coalition for the Capital Crescent Trail.
Native plants can breath easy thanks to the efforts of more than 675 Weed Warrior volunteers who work in parks in the Little Falls watershed removing non-native invasive plants. According to data just released by Montgomery Parks, watershed volunteers freed more than 1,722 trees and put in 2,031 hours to remove bush honeysuckle, porcelainberry vines, English ivy and other plants that are threatening our native trees and shrubs.
Little Falls Watershed Alliance Executive Director Sarah Morse leads the Montgomery Parks Weed Warrior pack for the third year for the most hours recorded by a Weed Warrior supervisor. Weed Warrior supervisors have special training and are allowed to lead community workdays that are open to the public. Sarah led 30 workdays on Park land in 2025 supervising 1,119 man hours. Sarah also leads workdays on State Highway land, in DC Parks, and in the Montgomery County Public Schools Forest Conservation Land for a total of 33 events in 2025.
Weed Warrior Supervisor Celia Martin also had an impressive year, leading 17 events in the Little Falls Stream Valley Park for 527 supervisor hours. Celia also works on MDOT land removing bamboo along Massachusetts Avenue to save the native trees and planting encroaching on the Falmouth Habitat project - another 14 workdays in 2025
We also have 38 Certified Weed Warriors working in the Little Falls watershed. Certified Weed Warriors have attended the Montgomery Parks Weed Warrior training and are allowed to work unsupervised in the Parks. More about how you can become a certified Weed Warrior is HERE.

Join the Mission - Get Certified, Participate in a community event
It’s against Montgomery Parks rules and regulations to remove plant material from a park unless authorized. That’s where the Weed Warrior Program comes in. By training and certifying citizens to remove non-native invasives from parkland, Montgomery County has a robust program that allows residents to help save our forests.
Sign-up for an Event: You can join one of our community workdays by visiting our events page and registering. We provide all necessary tools and gloves as well as instructions. Our workdays are open to everyone, but students under 14 must be accompanied by a supervising adult. No experience or previous training necessary.
Book a Private Event: We host dozens of workdays for office groups, civic groups, scouts, or just any group looking to make a difference. We provide tools, gloves, and a supervisors, you provide manpower. These days are arranged at mutually convenient times. Contact us at info@LFWA.org for more information.
Become a Certified Weed Warrior: Montgomery County certification program trains individuals to identify and remove non-native invasives. After receiving their “green card”, the weed warriors can work anywhere in the Park system without supervision. There is online training as well as in person training days. More information HERE.
