Invasive Management Area Program

Help restore parkland

Invasive plants prevent us from enjoying our forests. They degrade our natural ecosystems. Ever get stopped in the woods by climbing vines or shrubs with thorns? They may have been invasive species. Some of them, like multiflora rose, can completely swarm over a section of woods and block out everything else.

However, invasives can be thwarted. The Fairfax County Park Authority has a volunteer program that battles invasive species, removing them and replacing them with native species.

Get involved in protecting your local parks. Volunteer for the Invasive Management Area program. Even a few hours on a single day will help.

Students and scouts, do you need to earn some community service hours? IMA is the program for you! Sign up using the IMA Workday Calendar below to get involved.


Invasive Management Area VolunteerThe IMA calendar is your opportunity to volunteer. Use it to find IMA dates convenient for you. Youth, adults, scouts and groups all help. If you do not see a date that works for you, please contact the IMA coordinator who will happily help place your group.
