Invasive Species Removal Projects

For many years MNPS has co-sponsored invasive removal at Chapman Forest and Ruth Swann Park, supervised by Marc Imlay. 

Chapman Forest and Ruth Swann Park, Charles County

Sponsoring Organizations: MNPS, Sierra Club, Chapman Forest Foundation

Dates and Times: Usually the first Sundays and following Saturday, monthly, 10:00am – 4:00pm. Contact Marc, ialm @ erols.com, for information about specific days.

There are about 3,000 native plant species in Maryland, with 800 at Chapman Forest and contiguous Swann Park, 49 of which are endangered.

Help 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. Learn about best season for species, wet soil condition for pulling, 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.
