What are the two classifications of timber?

The two classifications of timber are softwoods and hardwoods.

Softwoods are derived from coniferous trees, such as pine, spruce, and fir. They are typically lighter in color and weight, and have a more uniform texture than hardwoods. Softwoods are commonly used for construction, furniture, and paper production.

Hardwoods are derived from deciduous trees, such as oak, maple, and cherry. They are typically darker in color and heavier, and have a more varied texture than softwoods. Hardwoods are commonly used for furniture, flooring, and cabinetry.
