DC CWMA Weed Warrior Program

The Weed Warrior program works with communities to reduce the negative impact of invasive, noxious weeds in public places, such as parks, trails, and open spaces. The program offers education about invasive weeds and methods for control or eradication of these weeds. The program provides opportunities where volunteers can participate in "hands-on" restoration projects; thus improving the wildlife habitat, aesthetic and recreational quality of our public places. Weed Warrior projects reflect the willingness of citizens of all ages to be involved and take part in the community as environmental stewards.

The DC CWMA will train community members and organizations to become weed warriors at various sites throughout the district.  These energetic volunteers assist park staff on a regular basis in monitoring and removing non-native invasive plant species (NNIs) from parkland.

To become a Weed Warrior Supervisor, you must participate in a 2-hour field training class with a wildlife biologist and complete a 2-part online course. The training emphasizes invasive plant identification, removal and control techniques, and working safely in the woods. Weed Warriors are then authorized to work on various sites within the District (including National Parks, DC Parks, etc)  on their own schedules and at their own pace.

Who are Weed Warriors?

Many Weed Warriors live near one of our parks/sites and do their volunteer work on a casual schedule. Others develop specific work programs, taking time each week or two to remove invasive plants—sometimes in the company of another Weed Warrior. Others choose to work with larger groups, such as those organized by community groups with permission from the parks department. Whether you work individually or with a group, you will contribute to the control of non-native invasive vegetation throughout the approximately thousands of acres of  parkland in the district.

If you are interested, and want to take the next step to becoming a Weed Warrior you must register for one of the field training sessions.
