Restoration and Conservation
Vine maple is planted in forested riparian habitats to help reduce erosion. Vine maples do well under a shade canopy and also in sunny locations. Deer and elk browse the leaves during summer. Birds and small mammals rely on the flowers, buds, and seeds. Squirrels and chipmunks eat and cache the seeds.
Due to the flexibility of the wood, vine maple has been used to build snowshoe frames, drum hoops and other small tools. The thin branches were good for weaving baskets and making fish traps. Vine maples are a very popular shrub/small tree for landscaping homes and businesses in North America.
