What are invasive plants? and Why do we care about removing invasives and planting more natives?
- A Guide to Invasive Plants in Massachusetts
Paul Somers, Rachel Kramer, and Bill Brumback. Massachusetts Division of Fisheries and Wildlife, 2006.
This great and inexpensive guidebook will help you identiify and manage 66 of some of the most invasive plant species in Massachusetts. At only $5 (and less in bulk), if you don't have this guide, you should.
- Field Manual of Invasive Plants for the Northeast
Bayard Ewing & Christopher Mattrick. New England Wild Flower Society.
Available only from the NEWFS bookstore-- contact them to purchase. Fully laminated so it will not dissolve in the rain, with close-ups and photographs of entire plants, making it useful for field identification. Includes many, but not all species.
- Massachusetts Prohibited Plant List
Between January 1, 2006 and 2009, it became illegal for the more than 140 species of plants to be imported, sold, or propagated anywhere in the state. Regulated by the Department of Agriculture, this list includes many plants running rampant in our gardens and taking over in our woodlands, state parks, and other areas. Controlling these plants is essential to preventing their continued spread and to further loss of biodiversity.
Key Organizations & Web Sites
