Invasive plants are non-native plants threaten the environment by taking over areas and decreasing the variety of native species. Invasives can also change soil quality, harm native animals, and even interfere with public works. Examples of terrestrial invasive plants in Concord include Black Swallowwort (Cynanchum louiseae), Common Reed (Phragmites australis), Autumn-olive (Elaeagnus umbellate), Asiatic Bittersweet (Celastrus orbiculatus), Honeysuckle (Lonicera maackii), Garlic Mustard (Alliaria petiolata), and Glossy Buckthorn (Frangula alnus). Please help us get rid of these problematic species! Meet us at the Replica house and be prepared to work! Wear sturdy shoes and long pants sprayed with bug spray. We will provide gloves. This is a free program, but there is a parking fee of $8 per MA vehicle, $10 out-of-state plates. No dogs are permitted unless working guides. Please call (978) 369-3254 for more information.
