Sycamore maples have a large tolerance for salinity, quality of soils, and exposed conditions. Because of its hardy nature, it can withstand harsh conditions, competing against native plants for important resources. These trees produce large number of seedlings. The paired samaras they produce are wind dispersed, aiding in further establishment of the species. By increasing in numbers fast in comparison to other trees, they can grow in dense stands and crowd out native tree species and successfully compete for sunlight, space and nutrients.
