The joint Soviet-Finnish venture, Ladenso was founded in 1990 on the basis of Pitkyarantsky integrated logging enterprise. Since 2004 Ladenso JSC is one of the subsidiaries of Stora Enso group of companies, and two years later, in 2006, the company got the FSC certificate (license number FSC-C022927). Since its formation, the enterprise has been applying the CTL method and the Scandinavian model of forest management.
Prior to the introduction in 2006 of the new Forest Code, the lease area of the enterprise included the forests of the first group where narrow clear-strip clearcuts were conducted, i.e. up to 70% of the annual allowable cut. The reforestation was carried out in all areas, and more than 60% of which by means of forest plantations with closed and open root systems. There was also seeding and natural reforestation promotion. For tillage modern and highly efficient equipment was used.
The next step was forest plantation care, first thinning in young stands. Apart from clearcuts, selective, multi-stage cuts, voluntary selection cuts, and thinning were applied. The share of young stands used to increase due to the forest plantation fund. The mean annual increment in the lease area was improving. The average mortality decreased due to the change in the age structure of the plantations.
The company has been cooperating all this time with the Karelian Forestry Research Institute. Long-term test areas in stands of all ages and forest types were set up. Practical results were obtained after 20 years of using this forestry technology.
Since 2006, all forests of the first group were reclassified as “protective forests” and, as a consequence, clearcuts in protective forests were banned for a number of reasons. A problem of sustainable use of forests by using only selective cutting appeared, as well as the problem of developing the annual allowable cut due to the increased logging space and low intensity of such logging in overmature stands, thus increasing the number of gradual felling, and the problem of gradual final felling without leaving the required number of viable undergrowth in overmature stands. The problem of thinning according to the existing regulatory acts and the inefficiency of the requirements for their conduct also became evident.
