As An Invasive Species in North America
Norway maples release chemicals to discourage undergrowth, which tends to create bare, muddy run-off conditions immediately under the tree. A. platanoides has been shown to inhibit the growth of native saplings as a canopy tree or as a sapling. The Norway maple also suffers less herbivory than the sugar maple, allowing it to gain a competitive advantage against the latter species. As a result of these characteristics, it is considered invasive in some states, and has been banned in New Hampshire and Massachusetts. The Norway maple is one of three species Meijer Garden Centers no longer sell; Meijer made this decision due to the tree's invasive nature. Despite these steps, the species is still available and widely used for urban plantings in many areas.
