They are also popular as subjects for bonsai, a natural art form produced by artificially stunting the growth of the specimen.
Many species yield good timber.
Acer saccharum Marshall and other species in eastern North America yield maple syrup. Contact with the wood and also the pollen of some species may have on occasion produced dermatitis. Whilst feeding, these insects excrete a sugary liquid known as honeydew which falls from the trees as a fine rain. Large numbers of aphids may also fall from the trees. The pollen of this and another species of maple has been implicated as a cause of airborne contact dermatitis by Lovell et al.
