Research into the forestry behaviour of private forest owners in Finland began 10 years ago. The private forest owners have been dichotomously classified into two groups, farmers and non-farmers. The farmer forest owner was considered to derive his main income (earnings) from agriculture. This classification is compared to the concepts in statistical publication Farm Economy 1976 (Maatilatalous). On the basis of this examination, it is recommended that researchers dealing with the behaviour of private forest owners should change their classification to agree with the concepts presented in the Farm Economy statistics. The recommended concept of farmer forest owner is understood as a forest owner who has taxable net incomes (state taxation) from farming. Other private forest owners are classified as non-farmers.

This paper examines the changes in forest ownership and the farm properties for sale from a business economic standpoint. The changes in forest ownership are examined on the basis of statistics and literature. The empirical data both for farms for sale and farms sold are based on the purchases made by the National Board of Forestry in 1972.
There are a number of ownership groups actively buying and selling forest land, thus giving alternatives for ownership changes. The National Board of Forestry has been active in the market since 1960. For instance, in 1972 it purchased 60% of the forest estates it was offered. Of the forest area put up for sale, 75% originated from private individuals, and 20% from inheritance sales.

During the next decade there will be a marked increase in the allowable cut in drained peatlands. At the same time, the mechanization in logging proceeds, and in short-distance haulage the use of forwarders will increase. This study, based on literature and some observations, deals with logging conditions in drained peatlands with special reference to the suitability of heavy logging machines for use in such terrain. In addition, soil frost and the bearing capacity of the frozen peat soil were studied.
Freezing of the soil in a drained peatland area depends prevailingly on the weather conditions during early winter. The factors influencing soil freezing of a drained peatland are completely different from those regulating the freezing of natural peat soils. The frost penetrates in general deeper in the drained than virgin peatland. The topmost peat layer does not, however, freeze uniformly. Generally speaking, the bearing capacity of a drained peat soil is lower than that of undrained peat due to lower water content.
It is concluded that heavy logging machines are probably not fitted for use in drained areas on peatland even if the average soil frost values recorded would suggest it. Moreover, because of their extremely superficial root systems, peatland forests are exposed to damages by heavy machines in thinning operations.
