More on invasiveness: In Belgium as in its native range, Acer rufinerve is an early successional forests species which occupies forest edges, small gaps and the understorey of acidic woodlands dominated by light-demanding trees (oaks). It mainly thrives in semi-shaded areas and diminishes in number as succession proceeds. It avoids dense forests dominated by beech trees. Belgian populations are established on acidic loamy to sandy soils (brown acidic to podzolic soils), often together with Prunus serotina. Trees produce a huge number of seeds that may be dispersed by wind over several hundreds of meters away from the mother tree. Acer rufinerve is commonly used as an ornamental and is planted in gardens and public green areas.

More on impacts: Field observations in Belgium suggest that the red-veined maple impairs the regeneration of other tree species and reduces the diversity of herbaceous plants where it develops dense thickets. Information on impacts is poorly documented in the scientific literature.
