Black locust: Decay resistant, tough & durable.

Black locust (Robinia pseudoacacia) is a member of the legume family; it can “fix nitrogen” in the soil. While native to the Appalachian Mountains, from Pennsylvania to Alabama, in the last century, it has spread to almost every state. With a widespread, shallow root system, it is ideal for thin soils where it will prevent soil erosion, and it is often used for strip-mine reclamation projects barren due to mining debris and acid soils.
