The use of habitats by one female moose Alces alces (Linnaeus, 1758) in a managed forest area was studied in 1993-1994. The home range area for the whole year 1993 was 4154 ha (the 90% minimum convex polygon). The area used during January-April in the first winter was 1888 ha (71% of the summer range in May-August). The core area (50% adaptive kernel) was 408 ha (9.8% of home range) in 1993. Forested peatlands were relatively intensively used by the moose. The old and middle-aged forests were used heavily up until the autumn. In the second winter with thicker snow cover the home range was smaller and the use of available habitats more uniform. The characteristics of stands used in the core area did not differ significantly from the average for the whole area. The availability of food was relatively high even in the old-forest habitats due to the forest edges rich in saplings, particularly in the vicinity of peatland. The moose fed mainly on highly available birch and used more Scots pine in the second winter. The availability of palatable saplings, dwarf shrubs and herbaceous plants appear to have seasonal importance in habitat selection. The tops of recently felled trees were utilized for periods lasting for several days. By combining the basic ecological elements, dynamic factors and effects of browsing, the habitat analyses could probably be useful for management planning in moose areas.
