English title: Development alternatives in the organization chains of Finnish forestry.

The aim of this paper was to shape and analyse certain alternatives in the development processes in the organization chains of Finnish forestry. The material was collected by analysing market structures and characteristics of competition with regard to raw wood and forest industry products.

The paper presents two alternative ways to rationalize the organization chains between the forest owner’s organizations and forest industry. In the price mechanism of raw wood originating from Finnish private forests there there has been increasing influence of the central organizations of the private forest owners and forest industry. In their relationship, the model of bilateral monopolistic competition can be chosen as a conceptual framework.

Under bilateral monopoly price is fixed as a result of negotiations between competitive parties, and the position and tactics within the negotiations are of great importance for the negotiating parties. Because of the competition, Finnish forest industry cannot compensate the increase in the production costs by raising independently the export prices of its products. This and the fact that the annual earnings of forest workers are fixed by law to the earnings of the workers in wood-processing industry, will cause pressure on stumpage prices.

In the paper two schemes are outlined. In the Scheme 1 a development alternative is described in which the organization chain of private forest owners is supposed to develop to the industry growing direction. In the Scheme 2 the organization chain of private forest owners is supposed to develop to the organizational orientated direction.

It is concluded that as long as the forest owners’ organizational orientated central organization is too weak to form a monopoly as counterweight to the monopsol of forest industry (except the industries of forest owners), it will consider the industry growing direction superior to the organizational orientated alternative.

English title: A proposal for the determination of total volume and utilization per cent of standing timber .

The present study gives an account of the dependence prevailing between the actual volume of timber crops, and, on one hand, the sum of cylindrical volume of individual trees, and on the other hand, the utilization per cent. This dependence is rectlinear if the volumes in question are calculated on a running-foot basis. The cylindrical volume of individual trees was calculated on the basis of cross-section area at breast height and the height of the trees. On the basis of the results, it seems that it is possible to simplify timber measurement.

English title: Grade distribution of Norway spruce logs in Southern Finland.

The aim of the present study was to find the factors influencing the distribution of Norway spruce (Picea abies (L.) H. Karst.) logs on various grades with special stress on the effects of the grade on the value of logs. The material was obtained from ten sawmills located in Southern Finland by grading a total of 13,559 logs.

The results showed that knottiness in its different forms of appearance is the most important factor influencing the quality of spruce logs. Its significance is clearly greater in spruce than in Scots pine saw logs. Among the other defects, the most common are crooks. Even scars and decay occur to a considerable degree, but other defects seldom affect the grade. The quality of butt logs is markedly better than that of top logs. Both in butt and top logs the smallest logs in diameter are of poorer quality. However, in the largest diameter classes the quality begins again to decrease.

The difference in the quality of logs of the same grade at various sawmills is very small. The results of grading at varying times at the same sawmill show greater differences than can be observed between different sawmills. However, the logs of sawmills that procure the timber from coastal areas and islands are inferior to those which procure the timber from the mainland.
