The forests managed by Wood Supply Sweden, mainly in central and southern Sweden, are rich in historical remains. People have been living in these areas for thousands of years. That puts special demands on how to plan in the field as well as how to use forest machines.
“Before harvesting work begins, all known historical remains that are already in the digital system are physically marked in the forest to make sure they are not damaged,” says Anna Kolmert Boström, one of three environmental specialists at Wood Supply Sweden.
Just keeping track of the known remains is not enough. Many new ones are found as the work progresses. The personnel at Wood Supply Sweden are trained in what to look for and what rules apply when historical remains are found.
“We add the new findings into our systems and mark them in the forest. Significant remains are also reported to the responsible regional authority. When the harvesting work begins, stumps of about 1.3 metres are left around the objects so they can easily be found,” says Anna.
Typical findings are charcoal kilns, stone walls, old roads and sometimes the remains of buildings.
“In some parts of the forests, there can be several remains per hectare, especially in the region of Bergslagen where iron has been produced for more than 1000 years. I don’t have a precise number, but we find hundreds of remains every year,” adds Anna.
