Two thirds of our country Sweden are covered in forests. The forest and mankind have been accompanying each other through the centuries. For hundreds of years, the forest has been one of our most important natural resources. Initially, it provided our ancestors with resources for domestic use, such as firewood, timber, carpentry and fencing materials. A material such as birch bark was incredibly important for roofing, and the birch was used as a raw material for a variety of household utensils and tools. Other processed wood products that came from the forest were wood tar and charcoal.
