Bunzo Hayata. (1929). Succession in the vegetation of Mt. Fuji. Acta Forestalia Fennica vol. 34 no. 4 article id 7217. https://doi.org/10.14214/aff.7217

­In different altitudes of the Mount Fuji in Japan occur succession of different tree species. For instance, at an altitude of 2,000 meters are pure stands of Tsuga diversifolia (Maxim.), under which is generally found young trees of Abies veitchii (Lindl.), but not of Tsuga. Abies veitchii is in its turn replaced perhaps with Larix sp. The succession of the forests of the volcano have reached maturity, which is not the case in the east–north-east flank of the mountain, where the Hōei eruption destroyed all vegetation in 1707. The vegetation had not revived even by the 1920s. The Hōei eruption site is compared to the much faster return of vegetation in mount Krakatau in the warmer tropical region. The succession of forests in the other parts of the mountain is described in detail. Finally, a succession theory is proposed that is opposed to the natural selection theory. The theory suggests that there is an Innermost Factor that controls the plant succession. According to the theory, every species, every formation, should die its natural death owing to the Innermost Factor.

The volume 34 of Acta Forestalia Fennica is a jubileum publication of professor Aimo Kaarlo Cajander.

Takuro Kishine. (1986). Optimizing simulation model on forest policy. Silva Fennica vol. 20 no. 4 article id 5300. https://doi.org/10.14214/sf.a27756

This paper designs an Economy-Welfare-Environment Adjustment System model (EWEAS model or EWE model in short) which consists of the circular flow of the economic, the welfare, and the environment system of forestry. That is, this model builds the relationship between the systems for material wealth and that for mental wealth.

The EWE model is designed as a complete open system model which describes the economy-welfare-environment circular system in forestry by linking up the internal system of forestry with the surrounding external systems. The EWE model can be manipulated as a policy formation or a policy decision model, and it is available for policy evaluation in the economic, the welfare and the environmental phase of forestry. The model is a basic simulation system model which is reliable in its reproductive fitness, stability and universality. Thus, this model ought to be useful in any country in the world as well as in Japan.

Shigeru Shimotori. (1986). Private and municipal forests and the forestry planning system in Japan - trends and problems after World War II. Silva Fennica vol. 20 no. 4 article id 5299. https://doi.org/10.14214/sf.a27755

In this paper, the author explains the characteristics of the Japanese forestry planning system and points out some of the problems found therein from the viewpoint of the management of privately-owned forests relating to the economic background and governmental policy.

The forestry planning system is a centralizes type of planning, the planning begins at the top and flows downward and outward the periphery. In order to make this planning system an effective instrument, the district forestry planning founded under the system must approach the problem of how to combine the resources of the forest with the district’s inhabitants and the forest owners; and further, the extent of the effective union of the district and the local timber manufacturing must be examined.

Ryoichi Handa. (1986). On the principles of Japanese forest policy since 1950. Silva Fennica vol. 20 no. 4 article id 5292. https://doi.org/10.14214/sf.a27748

In Japan many governmental projects have been promoted during 35 years since 1950, which were most active in the history of our forestry and wood industry. They were pushed forward for and by high economic growth. This article refers to the development of our forest policy and projects in those days. But as for the future of the forest economics, it is an urgent question to develop the comparative study between every nation’s experience. In order to contribute to this problem, the forest policy is divided into three fields and experiences are discussed.

Shigeru Tanaka. (1981). Forest cooperatives as a policy measure for small woodlands. Silva Fennica vol. 15 no. 1 article id 5103. https://doi.org/10.14214/sf.a15044

In Japan, there are 2,990,000 forest owners within the scope of Forest Cooperatives, 60% of which are members of forest cooperatives. These are the largest functional organizations concerning private forests in Japan. The majority of members are small woodland owners with less than 20 ha per person, and 90% of the members are of agricultural cooperatives. The variety of memberships makes it difficult for cooperatives to strengthen its solidarity. The article describes the legislation concerning cooperatives in Japan, characteristics of business, reforestation and logging made by the forest cooperatives, and reorganization of the forest workers of the cooperatives.

Steady expansion of the main activities of the Forest Cooperatives, i.e. logging, marketing and reforestation, has been seen during the past 20 years. Logging and marketing have been taken over from the timber-dealers, and reforestation has been expanded by the Forest Cooperatives on the members’ behalf.
