The United Nations General Assembly declared 2011 as the International Year of Forests to raise awareness on sustainable management, conservation and sustainable development of all types of forests. Moreover March 21 is World Forest Day.With 2.6 million hectares of forest, SCA is the largest private forest owner in Europe. Of SCA's forests used for active forestry, the company's ecological landscape plans exclude more than five percent from felling. In addition, more than five percent of the forest, in the form of trees, groups of trees and edge zones, is left untouched during felling to preserve the necessary conditions for biodiversity.For more than 50 years, SCA has conducted regular forest inventories, which are used as supporting data for calculating the forest’s long-term sustainable yield and planning the company’s long-term forest management. These yield calculations extend more than 100 years into the future.The long–term harvesting plan for SCA’s forests was updated in 2007. The inventories showed that the company’s current harvesting levels are sustainable.
