Abstract

In recent years, much attention has been paid to conserving forest biodiversity. This fact is not surprising, given that 65% of terrestrial taxa depend on forest ecosystems. The challenge facing future forest ecosystem managers is to conserve forest biodiversity and prevent natural degradation in the face of detrimental human activities. This review focuses on forest management issues in Sweden, where human activities have affected forests over a long period of time. In Sweden, the forests have been divided into small parcels for private ownership. As a result, forest management is contingent upon the desires of many individual landowners, greatly hindering the creation of large protected areas to initiate conservation practices. However, forest managers in Sweden have devised a new approach that focuses on timber productivity while also maintaining biodiversity. In addition to national parks and nature reserves, some productive forests, so-called "woodland key habitats," on private land harbor red-listed species that are protected from logging. New forest harvest practices, such as leaving live and dead trees as potential habitat for many biota (including threatened species), have been introduced throughout the country. As a result, Sweden has made biodiversity a priority in private forests used for timber production. Such novel matrix management practices would be very useful in restoring, conserving, and managing Japanese forests, which have similarly been inexorably changed by long-term human activity.
