What to do: Seedlings and small saplings may be pulled, cut or mowed. Larger plants can be controlled by herbicide.
What do do: Cutting is usually not enough. Trees can sprout from the roots of the Black Locust. Systemic herbicides should be applied to freshly cut stump, but even that may need to be repeated.
This shrub has white flowers in the spring and red berries in the fall. It originates in Asia but came to the U.S. for wildlife and food erosion control. Olive Autumn spreads easily and can out-compete and displace native species.
The shrub can grow up to 12 feet tall. It’s native to Asia and Europe and they were introduced as ornamental landscape plants. The issue is, they produce leaves earlier in the spring than most native species, which gives them a competitive advantage.
A deciduous tree that can grow 100 feet high, the black locust was brought to Massachusetts from the Appalachian and Ozark Mountains for erosion control and durable wood. It has white flowers and compound leaves. The saplings and smaller branches of mature trees have thorns. It can increase soil nitrogen levels, which can threaten native plans that have adapted to lower levels.
However, wind, water and wildlife can’t be prevented from spreading the seeds across the state, so many of these still exist. If you see these plants, steps are described below by Mass Audubon as to how to dispose of them. You can also contact your local conservation committee.
The Mass Audubon created a list of 31 invasive plants that are the greatest threats to Massachusetts’ natural environment. The following species of plants have been banned for importation, propagation and sale in Massachusetts by the Massachusetts Department of Agricultural Resources.

What to do: Removing saplings by hand or cutting usually works. For larger plants, systematic herbicide on freshly cut stumps is effective. Take note, Bush Honeysuckle in wetlands may be protected by state statutes.
Invasive plants in Massachusetts: 31 types that could be growing into a jungle in your backyard By Michael Bonner | MassLive Tree pollen is already in the air, grass and other shrubs
Dry beach areas are home to plants that can tolerate wind, wind-blown sand, salt spray, and regular interaction with waves and flood waters. Certain plants actually thrive on accumulations of sand to help them grow. The plants listed below are appropriate for dry beach conditions in Massachusetts.
The plants listed below are good choices for the rugged coastal conditions of Massachusetts. The Coastal Beach Plant List, Coastal Dune Plant List, and Coastal Bank Plant List give recommended species for each specified location (some species overlap because they thrive in various conditions). For a printer-friendly version of this web page, see the PDF copy of the Coastal Landscaping in Massachusetts – Plant List (PDF, 605 KB).
A native plant species is a plant that is considered indigenous and naturally occurring to the region since pre-Colonial times (before 1500) or arriving more recently without human intervention. For purposes of this website, a native plant is one that occurs naturally in eastern Massachusetts.
Rugosa rose (Rosa rugosa) is considered to be non-native (native to eastern Asia) and potentially invasive in some regions or habitats of Massachusetts and may displace desirable vegetation if not properly managed. Though the shrub is extremely tolerant of sea spray and effective at directing pedestrian access away from dunes, it has the ability to form dense thickets that shade and outcompete other native bank, beach, and dune plants. Rugosa rose can also spread vigorously through both seed dispersal (carried by the rose hips) and underground rhizomes. Therefore, care should be taken when considering planting rugosa rose on coastal properties.
Fronting dunes and exposed secondary dunes are habitat for plant species that can tolerate wind, wind-blown sand, and salt spray; endure interaction with waves and flooding; and often even thrive on sand inundation. The plants listed below, as well as those listed above for Dry Beach areas, are appropriate for these environments along the Massachusetts coast.
Areas landward of the top of coastal bank are more protected from wave action, but may still be significantly affected by wind and salt spray. The plants listed below, as well as those listed above for Exposed Areas of a Coastal Bank, are appropriate for these more protected areas of the coastal bank in Massachusetts.
Photos and additional information for selected species are available on the following pages:
More protected secondary dunes are able to host a greater variety of plant species, because they are more sheltered from wind, salt-spray, and wave action. The plants listed below, as well as those listed above for Exposed Areas of a Coastal Dune, are appropriate for these more sheltered dune environments in Massachusetts.
Sheltered intertidal areas (between the low-tide and high-tide line) of beach, marsh, and even rocky environments are home to particular plant species that can tolerate extreme fluctuations in water, salinity, and temperature. The following plants are appropriate for these conditions along the Massachusetts coast.
