Andiroba (Carapa guianensis) is found throughout Central and South America, from Cuba to Peru and Brazil. It is an extremely tall tree, reaching heights of 100 to 170 feet. Diameters are often 5 to 6 feet. The central stem is often straight and free of branches for 50 feet or more. As a result, clear lumber is common.

Soft, light, low strength, but resistant to decay, insects.

One of the seven "true fir" species to produce commercial lumber.

Giant chinkapin (Chrysolepis chrysophylla), sometimes called golden-leafed chinquapin and golden-leafed chestnut because of the minute golden scales on the leaf bottom, is a western hardwood and is an evergreen.

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.

Most uses for Douglas-fir today capitalize on the wood’s high strength, yet the beauty of this wood makes it favored for millwork, furniture, cabinets and flooring.

Blackgum, also called black tupelo, tupelo gum, or just tupelo, is a tree that loves to grow in water and water-soaked soils.

Redwood (Sequoia sempervirens) is a wonderful evergreen species, with mature trees commonly reaching 300 feet high and 12 feet in diameter. (Giant sequoia is even larger and is a different species.) 

Hackberry is a lumber species that does not stand on its own too often. Rather, it has been used as a substitute for red oak, ash or elm. Indeed, hackberry has strong grain and porous structure, so it is quite similar to these other three species.

Butternut, sometimes called white walnut, is great for carving and other uses, but it is potentially an endangered species.
