- Softwood: This is the wood from coniferous trees, such as pine, spruce, and fir. It is generally less dense than hardwood, making it easier to cut and shape.
- Plywood: A type of manufactured wood made from thin layers of wood veneer glued together.

Usage
Timber is used in various industries and for different purposes. It is primarily used in the construction industry for building houses, bridges, and other structures. It is also used in the furniture industry for making furniture. Other uses include making tools, sports equipment, and paper products.
Environmental Impact
The extraction of timber has both positive and negative impacts on the environment. On one hand, it contributes to deforestation and loss of biodiversity. On the other hand, when managed sustainably, timber production can provide an important source of income for communities and contribute to carbon sequestration.
