Weed Warriors on Campus

Weed Warriors on Campus is a volunteer event for UMD students that hosts educational invasive species removal events. We meet every other Wednesday from March to October, weather permitting. During cold months, please wear appropriate warm outdoor clothing. During hot months, please wear light-colored, loose-fitting clothing and bring water to drink. Hats are always a good idea. 

Registration is Required (there will be no event Mar 20 due to spring break):

Invasive species are non-native organisms that cause harm to the environment, economy, or human health (UMD Extension). Each event includes an explanation of invasive species in Maryland, a demonstration of which invasive species we will be targeting, and group removal of target plants. Removing these species will improve the health of our native trees and plants, as well as the insects, birds, and animals that our native plants support.  

Weed Warriors on Campus is a great way to get outdoors on campus and meet other students that care about the environment!

This program is led by the University of Maryland Arboretum & Botanical Gardens and the University’s Environmental Finance Center.

This group is inspired by the successful program in Montgomery County Parks, Montgomery Weed Warriors. If you live in Montgomery County, we encourage you to register for their programs as well to support invasive species removal across multiple counties.
