The aim of the study was to describe the total change of forest area in non-industrial private forest holdings in southeast Finland, 1986–1991. The average gross decrease of forest area was 1.7 hectares, whereas the average gross increase was 1.2 hectares. Consequently, the average size of holdings decreased from 32.5 to 32.0 hectares. The most important factors affecting the changes of forest area were the inheritance system, resulting in a decrease of 0.7 ha, and reclassification of forestry land, producing an increase of 0.4 ha per holding. The increase of small, under 10 ha holdings accounted for much of the structural change.

The amounts of harvestable logging residues and stump and root wood were examined in the area where 100,000 solid m3 of stemwood was cut in 1975. The cutting amounts of stemwood from work sites suitable for harvesting of logging residues was 35,000 m3, and suitable for harvesting of stump and root wood 38,000 m3. The increase in the yield of wood (without bark) from logging residues compared with the unbarked stemwood was 2.4%. The same percentage of wood from stump and root wood was 5.0–5.8% depending on the harvesting loss.
