Further, in 1990, the Massachusetts Natural Heritage and Endangered Species Program found that 51 of the 209 invasive alien plants are aggressive and most problematic in Massachusetts. In their natural habitats, plant populations are kept in check by the pressures of competition with other plants, predation by insects and animals, and infection by pathogens. When a plant is introduced to a new area, it leaves behind many, if not all, of these natural controls. Freedom from these biological and physical constraints allows the introduced plant to multiply unchecked in its new environment. Moreover, invasive plants often possess one or more certain characteristics that enable them to compete aggressively within its new niche.
Early detection is important in containment and subsequent eradication of the alien species.
Once establishment and spread of the pest occurs, control becomes more difficult. Control can be achieved by mechanical, chemical, or biological means as indicated on each invasive species information sheet. Use these information sheets to help identify and eradicate invasive species. BUT, across from each invasive, we have listed a species that is native and would be similar in growth, appearance or food value for wildlife. Known as the Kudzu of the north Bearberry - provides berries, this is a ground cover, not a climbing, twining vine.
