Vegetation Type Boreal forests dominated by Norway spruce and Scots pine. Partly managed, partly natural forests.
Description of study site The study site consists of two separate areas in continuous habitat (see Figure 1.1 in Ekman & Griesser 2016). The southern area (53km2) is located in intensively managed forests. In this area the primeval forest is interspersed with clear-felled areas and plantations. The northern area is located in a nature reserve (Reivo, 30 km2) with continuous primeval forests unaffected by forestry for over the last 200 years. Managed forests are dominated by the commercially valuable pines, making forests more open as Scots pine has branches in the crown of the tree while spruce often has branches almost down to ground level.
