Amur maple is a multi-stemmed, tall shrub or small tree, 10-20 ft. (3-6m) tall with opposite, simple leaves. The leaves are 3-lobed, doubly-serrate, 1 ½ -3 in. (3.8-7.6cm) long, and ¾ – 1 ½ in. (1.3-3.8 cm) wide. Flowering occurs in the spring, when small, yellowish-white, fragrant flowers develop in a small panicle. The fruit is a red to brown, double samara. This species prefers moist, well-drained soils in full sun or partial shade. Amur maple is a native of northern Asia and was introduced into the United States as an ornamental around 1860.

Management Options:
A. Hand Pulling
Control can often be accomplished by hand-pulling for small populations (less than 1/4 acre). Plants pulled early in the season are much smaller and easier to manage.
B. Cutting & Mowing
Mowing (or brush hogging where woody plants are present) is suited to non-rocky, open areas that are not too steep for the equipment. Obviously, mowing affects all plants mowed, not just the target species. Equipment should be cleaned prior to being brought to the site and should be thoroughly cleaned of all seeds and plant parts before leaving the site.
C. Propane Torch
Backpack-mounted propane torches can be used for invasive plant control. This method uses targeted fire to heat the base of a plant, killing it. Some plants with developed roots may resprout after this treatment. Safety training is needed before using this method.
D. Herbicides
Herbicides are pesticides used for vegetation management. Herbicides can be a valuable tool in controlling invasive species, but they must be used with caution.
Always read the entire herbicide label and apply herbicides according to label directions. Wear the personal protective equipment specified on the product label and heed any and all environmental restrictions stated on the label.
Most herbicide products, especially those marketed to homeowners and small property owners, are classified as “General Use” pesticides. Only licensed pesticide applicators are allowed to purchase or apply “Restricted Use” pesticides.
E. Grazing
Grazing means using animals to eat plants.
