CRITIQUE

Amur maple has invasive traits that enable it to spread aggressively. This tree is under observation and may be listed on official invasive species lists in the near future. Review of risks should be undertaken before selecting this tree for planting sites. One tree can produce more than 5,000 two-winged seeds that are widely spread by wind. In open woods, Amur maple displaces native shrubs and understory trees. In prairies and open fields, it can shade out native species of plants, disrupting the ecosystems that plants and animals depend on.
