Amur maple

Amur maple
(Acer tataricum subsp. ginnala)

Multi-stemmed deciduous tree or shrub in the maple family.



Overview

Regulated areas of Amur maple
This species is Restricted (Orange counties)

Other names for this plant include:

  • Common names: Siberian maple, ginnala maple
  • Scientific names: Acer tataricum, Acer ginnala

Ecological threat:

  • Invades open grasslands, open forests, prairies, forest and field edges.
  • Outcompetes native shrubs and understory trees, reducing overall biodiversity.
  • Can shade-out native species in prairie ecosystems, converting prairie community to shaded shrubland or woodland.
  • United States Forest Service designates this species as invasive in several eastern states with similar climate zones.
  • Trees produce abundant, wind dispersed seed that germinate readily.
  • Tree are tolerant of a wide range of environmental conditions, and more drought and shade tolerant than native maples.
  • May contain allelopathic chemicals, inhibiting root development of desired species.

Classification in Wisconsin: Restricted (all cultivars exempt)

Species Assessment Groups (SAG) were assembled to recommend a legal classification for each species considered for NR 40. The recommendation for Amur maple was based upon this literature review developed by the department.

Identification

Leaves & stems: Leaves and stems are opposite, with two leaves per stem node. Leaves are simple with three shallow lobes; bright green in color turning scarlet red in fall. Bark is grayish-brown and smooth when young, developing furrowed striations with age.

Flowers: Panicle flowers are fragrant and pale yellow-whitish in color.

Fruits & seeds: Red samara (helicopter) seeds (borne in pairs) have tight angled, almost parallel wings. Samaras travel long distances in the wind and readily germinate.

Similar species: Amur maple can be distinguished by other maples by the narrow leaf shape with three shallow lobes.

Control

Mechanical:

  • Amur maple saplings are easily pulled by hand.
  • Larger trees can be cut, but do resprout.
  • Prescribed fire in prairies can be effective means of control.

Chemical:

  • General herbicide treatments are effective.
  • Cut-stump treatment glyphosate, and basal bark treatment or frilling with triclopyr is successful.
