The document categorizes and describes different types of trees found in Indiana state parks. It divides trees into hardwoods and softwoods. Hardwoods are nut-bearing, non-coniferous trees like oak, maple, and hickory that are more abundant. Softwoods include coniferous pine, cedar, and hemlock that grow cones instead of nuts in areas unsuitable for hardwoods. Hardwoods are preferred for heating due to burning longer, while softwoods are used for cheaper furniture and construction framing.
