Viken Skog has for a long time invested significant amounts to ensure long-term sales of timber and development in the value chain. Historically, the forest owners' associations that Viken Skog is founded on were among the initiators and a significant investor in large parts of today's forest industry. Viken Skog was one of the largest individual shareholders in Norske Skogindustrier ASA until March 2012. Today, Viken Skog has industrial commitments in Moelven Industrier ASA, Begna Bruk AS and Hallingdal Trepellets AS. In addition, significant resources are invested in the development of a new and future-oriented forest industry through the wholly owned subsidiary Treklyngen Holding AS.
