Invasives Watch

The presence of non-native, invasive species or "bioinvaders" has emerged as one of the leading environmental and economic threats to our coastal area.

Become a Citizen-Scientist. Volunteer! We will train you.
SSCW will provide you with the knowlege and support to make a difference.

Coastal Habitat Invasives Monitoring Program. Attend a training session to learn more about invading crabs, shrimp and sea squirts. Then join us at monthly summer visits to a rocky shoreline or floating dock to observe and record the presence of these species.

Salem Sound Coastwatch expanded our coastal monitoring of marine invasive species to the deeper waters of Salem Sound by conducting a unique study of fouling on lobster traps in and around the sound. Through a partnership with local commercial lobstermen, and a lot of time working on a fishing boat, fouling organisms on traps were identified and cataloged, with some very interesting results.

Phragmites australis also known as common reed, is an invasive plant that can spread throughout a wetland, crowding out other more productive plants with its dense roots and tall stalks. It is a serious threat to our wetlands. SSCW monitors and documents methods to control small stands of Phragmites and shares control information with conservation agents/commissions and private landowners.

Pepperweed is a recent invader to Salem Sound and the North Shore. It has the potential to colonize the upper edge of salt marshes and beaches as well as disturbed areas along roadways. Join us to locate and remove pepperweed by pulling plants twice a summer.

Our watershed uplands have invasive plant problems too. Oriental bittersweet vines wind around trees eventually strangling them. Purple loosestrife takes over a freshwater wetland. There are ways to fight their spread. Join us on a service day to combat these invasives and others like them.
