This video shows the felling of two Sitka spruce trees in a Scottish plantation forest. Normally, commercial felling is done using harvesting machines, but these trees are being felled for a research project. The trees in this particular forest are about 40-years old and will soon be harvested and the logs sent to a sawmill. The land will then be replanted with new trees to provide timber in the future. Wood grown in this way can be used in place of materials that are not renewable, such as concrete and plastic.
Research helps us understand the factors that affect the properties of wood that are important for us, such as strength and stiffness.
