Coniferous timber imported by rail from the Soviet Union in Finland was studied for the presence of potential forest and timber pest beetles. Systematic samples of fourteen lots of pine pulpwood were examined. Seven of the lots originated from the European parts of the Soviet Union and seven from Siberia. 23 species of Scolytidae and about 18 other phloeophagous species were found including three species new for Finland: Phaenops guttulata (Buprestidae), Ips subelongatus and Orthotomicus erosus (Scolytidae).

Silva Fennica issue 52 includes presentations held in professional development courses, arranged for foresters working in public administration in 1938. The presentations focus on practical issues in forest management and administration, especially in regional level. The education was arranged by Forest Service.

This presentation describes the Timber Measurement Act, adopted in 1938, and its application.

Selling through agencies became common Finland in the end of 1800s in timber sales and export. No joint marketing organization has been established in the sawmilling industry, as has been done in pulp and paper industry. The aim of this report was to discuss need for the agencies in the post-war situation.

The paper concludes that the timber agents fill their post even at present under the changed conditions of the timber trade. The Finnish sawmilling industry is based on a majority of small sawmills, which have difficulties in keeping up foreign connections themselves. Even to the somewhat larger sawmills, which have a salesman of their own, the services of a domestic agent can be recommended. The number of agencies has markedly decreased during the war. With 120 agencies active in Finland it is evident that a considerable part of them will disappear. In Sweden the Association of timber agents has only 33 members. In comparison to other countries, the Finnish agency firms have the greatest number of joint-stock companies. The companies are concentrated in Helsinki. A good solution for co-operation in the sector could be to found an independent timber agent’s association.

The present paper presents a study on the works of ancient writers that deal with trees, forests and the use of forests before the time of actual forest sciences. The work describes the development of knowledge pertaining to the forest and trees and the progress made on utilizing them. This second part of a series of two articles is concerned with logging, transportation and trade of timber, as well as procurement and trade of other forest products. These activities have been practiced as long as the history of mankind is known.

The article introduces the most important ancient written sources from the standpoint of the subject of the article, and related modern literature. The second part describes the texts concerning felling and primary conversion, and skidding and transportation. The third part concentrates on timber trade, and the fourth on the procurement and trade of other forest products.

In terms of assessing economic impact, one of the most important elements in the wood supply chain is the measurement of round wood. Besides the one-by-one measurement of logs, logs are often measured when stacked at the forest road. The gross stacked volume includes the volume of the wood, bark and airspace and is widely used for industrial wood assortments. The increasing international attention given to photo-optical measurement systems for portable devices is due to their simplicity of use and efficiency. The aim of this study was to compare the gross volumes of hardwood log stacks measured using one widespread photo-optical app with two manual section-wise volume estimations of log stacks based on the German framework agreement for timber trade (RVR). The manual volume estimations were done starting from the left (RVR_left) and right (RVR_right) sides of the log stacks. The results showed an average deviation of the photo-optical gross volume estimation in comparison to the manual estimation of –2.09% (RVR_left) and –3.66% (RVR_right) while the deviation between RVR_left and RVR_right was +2.54%. However, the log stack gross volume had a highly significant effect on the deviation and better accuracy with smaller deviation were reached for larger log stacks. Moreover, results indicated that the gross volume estimations of higher quality log stacks were closer for the three analyzed methods compared to estimations of poor-quality log stacks.
