Parts of the remote pine forests of North Karelia, one of the Finland's most heavily wooded areas, are scarred where heavy snowfall and wind have uprooted tightly packed trees. The jagged timber is left where it fell, either too diseased or damaged to harvest. In nearby Joensuu, the regional capital and home to the European Forestry Institute, industry experts are warning that the ugly gaps are not a phenomenon confined to Finland's eastern-most province-but a symptom of a malaise spreading across the continent.
