River Birch
Betula nigra

Medium-sized tree that may grow to a mature height of 50-75' and width of 35-40'. Can grow to 20-30' in 10 years. Well suited for bank stabilization, shoreland and floodplain restorations on mesic-to-wet soils. Its ability to thrive on moist sites makes it useful for erosion control and rain gardens. This species is long-lived and fairly disease resistant. It is used in yards and landscape designs. Fast-growing, likes moist soil, can be messy.
