 The
Amur maple displaces native shrubs and understory trees in open woods,
and shades out native grasses and wildflowers in savanna habitats.
A prolific seed producer, Amur maple is becoming invasive in the
northern United States. Extensive wild populations have been found
in Illinois and Missouri. It resprouts easily from the cut stump.
A native of central and northern China, Manchuria and
Japan, Amur maple was introduced to North America in the 1860s. It is still
being sold commercially as an ornamental and for wildlife and shelterbelt
plantings. |
