This paper comments on the article written by Simo Hannelius that is published in the same issue of Silva Fennica (Who is the non-farmer forest owner? Silva Fennica 14 no. 4). Hannelius suggests 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, and that 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 would be classified as non-farmers. Veli-Pekka Järveläinen states in his opinion that when distinguishing a farmer and a non-farmer, the key criterion should be the profession, which has been proved to be an important parameter in behavioural research.

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.

The concept of the internal rate can be defined as the rate of interest, which if applied to expenditures incurred at different times, gives a compounded sum equal to revenues compounded at the same rate for the same time. This concept has long been used in forestry, particularly concerning the development of a stand, because in this case there is a time difference between many items of expenditure and revenue. Several terms have been used or the notions derived on this basis. The term internal rate of return has begun to appear only recently. This article explains different variations of the concept and its different names, together with some related concepts and terms.

The technical term reduced yield stands – sometimes reduced yield soils – is widely used in the Finnish forest literature. However, there is no clear definition of the notion reduced yield and no explanation of how this notion is measured in the classifications. Some committee reports and bill proposals and some laws and statutes use the reduced yield forest soil. No definition can be found. In my opinion the term reduced yield forest soils ought to be completely abolished until forest soil experts can perhaps define what it means, if they consider such a concept useful.
Explanations for the term reduced yield stands can be found in the descriptions of classification systems of stands. According to them, the criterion is partly silvicultural (site, species of tree), partly mensurational (volume, sometimes growth), partly economic. No explanation is found as to how the economic aspect is measured, nor about the limit of a full yield and reduced yield.
In my opinion such a term is confusing. I therefore suggest that the term reduced yield stand ought to be abolished. If something is needed instead, I suggest the term understocked stand, defined as a growing stock under certain percentage of a fully stocked stand. The notion of economic reduced yield cannot be generally tied to certain silvicultural and mensurational characteristics of stands. The economic aspect of certain kinds of stands may differ, depending on the owner of the forest and his economic situation, the location of the forest, the composition of the whole forest ownership unit, etc.
