Which term is used to refer to trees that grow quickly and are often used for timber production?

The term that refers to trees that grow quickly and are often used for timber production is "softwood trees." Softwoods primarily come from coniferous trees, which typically have a faster growth rate compared to hardwoods. These trees, such as pines, spruces, and firs, are highly valued in the timber industry due to their rapid maturation and the ease with which they can be harvested and processed.

Additionally, softwood species are commonly used in construction, paper production, and various other wood products. Their characteristics, such as light weight and ease of machining, further contribute to their popularity in the timber market. In contrast, hardwood trees generally grow more slowly, making them less desirable for quick timber production despite their often denser and more durable wood. Shade trees, while important for providing cover and aesthetic value, do not specifically denote trees used for timber. Fast-growing trees is a general description and does not specify the type of wood or its common use in the timber industry.
