Öland is an island in the Baltic sea at the south eastern coast of Sweden. The ground is mainly limestone. Historically Öland was an important source area for oak wood. Almost all buildings except the churches was burnt down by danish troupes 1677, why old wood is rare. A source for dendrochronological samples are the great amount of post mills (more than 300). Most of them are made of oaks felled in the 18'th century.
There are also some pine forrests on the island. The most important is the Böda area at the very northern part. A smaller pine forest is also at central west coast (Rälla tall)
