Invasive Plants

A species is invasive if it is not native to a particular ecosystem and if its introduction does or is likely to cause economic or environmental harm. Invasive plants can flourish better than native plants and they often displace rare and endangered species that provide habitat for wildlife. These plants also inhibit the growth and regeneration of native trees. Why invasives outcompete natives: 

• Adaptation to disturbed and "edge" sites that predominate in urban areas
• Not eaten by local wildlife, free from competition and herbivory
• Production of large amounts of seeds
• High seed germination rate
• Ability to spread by underground runners or rhizomes

Become a Volunteer

To join volunteers and work hands-on to restore habitat in our parks, pre-register here.  You can also contact jsoles@arlingtonva.us to schedule one for your school, church or business group, or to otherwise participate in this program.  

Volunteers:

• Save trees by cutting back vines that strangle or smother them.
• Slow the spread of invasive plants by removing them before they go to seed, or by cutting off fruit and berries where eliminating the whole plant is not possible.
• Provide maintenance-level plant removal after vendors or County staff have completed preliminary work.
• Learn to identify both invasive and native plants.
• Monitor target areas and serve as a quick-reaction force to eliminate newly established plants before they spread.
• Dress for the weather, and enjoy time in the great outdoors!
