Explanation:
Classification of Lumber
Trees are classified as either softwood or hardwood, as shown in Table 3. All lumber is therefore classified in the same way. The terms “softwood” and “hardwood” can be confusing since some softwood lumber is harder than some hardwood lumber. Generally, hardwoods are more dense and harder than softwoods. Lumber can be further classified by the name of the tree from which it comes. For example, Douglas fir lumber comes from a Douglas fir tree; walnut lumber comes from a walnut tree, and so forth.
