Invasive Species Removal and Habitat Restoration Outings
click for print view


Projects for ridding important habitats of invasive species continue throughout the state, throughout the year.


Become an Urban Weed Warrior!
Baltimore City Recreation and Parks has started its own Urban Weed Warriors program. Weed warriors can come to any of the sessions listed below to learn about the non-native invasive problem in Baltimore City parks. Training will include weed ID, removal techniques and native alternatives to exotic flora. The training will lead to certification as a weed warrior, whereby volunteers can work on their own to help control non-native invasives in Baltimore City parks. There will also be information about organized weed-pull activities throughout the spring and summer. Please contact Kimberley Mead, Weed Warrior Coordinator, at or 410-396-0359, for directions, RSVP or with questions.

We’ll pull Japanese honeysuckle, English ivy, porcelain berry and other invasive species that are crowding out Maryland natives and smothering trees.

No experience is necessary! Tools and gloves will be provided. Time, 9:30 a.m. til noon;  location, Meadowood Park, 10650 Falls Road, Lutherville-Timonium, Maryland 21093.

Caroline County

Adkins Arboretum

Adkins Arboretum on Maryland’s Eastern Shore is seeking volunteers to assist the staff in the removal of invasive non-natives on the Arboretum’s 400-acre site. Volunteers will be trained by the Arboretum staff. Workdays are Wednesday from 1p.m. to 3 p.m. For more information, contact Sylvan Kaufman at 410 634-2847, ext. 24.

Charles County

Chapman Forest and Ruth Swann Park

Dates: First Sundays and following Saturday, monthly. Time: 10 a.m. – 4  p.m.

Remove invasive non-natives from the 200-acre Swann Park and 800-acre portion of Chapman Forest designated Chapman State Park. There will be time for plant identification and a beautiful beach lunch. Participating organizations include Maryland Native Plant Society, Sierra Club and Chapman Forest Foundation.

  There are general methods and species-specific methods, such as best season for species, wet soil condition for pulling, handouts, extent of area of natives seen rescued, delayed gratification, targeted use of herbicides, and matching funds for staff to do what volunteers find hard to do.

 Non-native invasive plant removal will reach maintenance phase following a major work effort at each site in the Mid-Atlantic region and around the world for about three to five years to remove the massive populations of species. Regular stewardship projects are conducted in all seasons including winter, early spring, late spring, summer, and late summer.   This high-intensity program is followed by a low-intensity annual maintenance program for plants we have missed, plants emerging from the seed bank, and occasional plants migrating in from neighboring areas.

 Casual clothing, long sleeves and pants, sturdy comfortable walking boots/shoes, gloves are encouraged for these events.

 For information about the area and map, see

Montgomery County Parks
Weed Warriors Wanted!

The Maryland-National Capital Park and Planning Commission’s (M-NCPPC)Forest Ecologist is assembling a team of volunteers (Weed Warriors) to monitor and remove non-native invasive plant species in Montgomery County Parks, and we need your help! As a Weed Warrior volunteer, you will receive a short training session from the forest ecologist in the identification of, removal and control techniques for non-native invasive plants. Weed Warriors can then work at their own pace and choose a schedule that best suits them. Many current Weed Warriors live near a M-NCPPC Stream Valley Park or Regional Park and do their volunteer work while walking their dogs or taking an occasional hike through their neighborhood park. Whether you choose to work individually or in a group, your efforts will contribute to the control of non-native vegetation in the 32,500 acres of Montgomery County parkland. Contact: Carole Bergmann, M-NCPPC Forest Ecologist, at 301-949-2818 for more info or to sign up.

Little Paint Branch Park and Cherry Hill Road Community Park, Beltsville
March 9, March 25, and April 3, all 10 a.m. to 3 p.m. . Meet at the Beltsville Community Center parking lot at 10 a.m.  There are full indoor toilet facilities and a large seating area for lunch. We will continue the wonderful progress accomplished last year by the Americorps workers, General Electric Volunteers, Robert Goddard French Immersion and Montesori Elementary School, Washington Quaker Work Camps, and World Bank volunteers at Little Paint Branch Community Park.

 Our day will include natural history and special features of the park, methods and reasons for the project to control the spread of invasives. Native flowers and other plants will be identified as we work to rescue them. There will be a sign-in and safety orientation with handouts. Gloves and tools are provided. Our objective is to remove the invasives to allow natives to grow back.

 Directions:  Take U.S. 1 north from the Beltway. Go about 1 mile, passing the National Agricultural Research Center, and turn left at the light on Montgomery Rd. Go 3 blocks and turn left on Sellman Road. Go about 5 blocks and turn right into Little Paint Branch Park at the bottom of the hill.

 Some background information on the project:  Several of the worst invasive species in the Mid-Atlantic region, including English ivy, Asiatic bittersweeet, garlic mustard, bush honeysuckle and porcelain berry, are in the early stages of invasion in this park. Japanese stiltgrass covers about 5% of the park. Research indicates that Japanese stiltgrass is a major contributor of nitrogen pollution in the Chesapeake Bay, and reduces by half the ability of any land it dominates to hold water and release it slowly. Non-native invasive plant removal will reach maintenance phase following a major work effort at each site in the Mid-Atlantic region and around the world for about three to five years to remove the massive populations of species. Regular stewardship projects are conducted in all seasons including winter, early spring, late spring, summer, and late summer.

This high-intensity program is followed by a low-intensity annual maintenance program for plants we have missed, plants emerging from the seed bank, and occasional plants migrating in from neighboring areas.

 The project supporters are now removing English ivy, wineberry, periwinkle, ground ivy, Japanese pachysandra, bush honeysuckle, and multiflora rose to rescue the incredible diversity of native plants and animals at this particular park. Unlike most parks in the area, the 150-acre Little Paint Branch Park is in the early stages of invasion and is essentially the native plant nursery for the Paint Branch itself. Please contact, Marc Imlay, Ph.D., Conservation Biologist, Anacostia Watershed Society (301-699-6204, 301-283-0808) for more information.
