Railway forests have been managed in Japan since 1893. This article analyzes the historical changes of railway forest management and the managerial and social backgrounds behind the changes focusing on the multi-objective aspects of the management. The information used in this article was obtained at hearings at the East Japan Railway Company and the surveys of literature provided by the company. The railway forests have been managed not only for disasters prevention but also for timber production. While the role of disasters prevention has been unchanged and remained as the main objective of the management through its history, there have been considerable changes in the objective and the management systems regarding timber production. In the early stage of the management, timber production was considered as an important objective, and timber produced from the railway forests was utilized in various ways including sleepers. However, in the 1960s the timber production aspect of the railway management underwent changes due to the changes in the economic circumstances surrounding Japanese forestry and the problems in the management of the Japan National Railway that then owned all of the railway forests in Japan. Nowadays, timber production is no more an objective in railway management. The East Japan Railway Company has recently started a new experiment of converting some of artificial stands into natural stands, as the latter can be maintained without labor inputs.

Soil microbial biomass in forest soils with different silvicultural practices were measured by fumigation extraction method. A secondary forest of Pinus densiflora mixed with Quercus serrata has been cut on March 1994 and half of the clear-cut area has been slash-burned on August 1994. Soil organic layer and surface soil from 0cm to 5cm in depth were collected on April 1995 and July 1995. Average soil microbial biomass was highest at the secondary forest and lowest at slash-burned both for the organic layer and the surface soil. In most of the study plots, the average soil microbial biomass were higher on the ridge than the bottom of the slope and, also higher on July than on April. Detrimental effect of clear-cutting and slash-burning on soil microbial biomass were confirmed one year after those event.

The object of this paper is to investigate variation of leaf morphological traits in Kunugi (Quercus acutissima) and Abemaki (Q. variabilis) inhabiting Chugoku district. We collected leaves from 95 individuals in two pure and three mixed stands of these species. Then we investigated their hair types of leaves using Scanning Electron Microscopy (SEM) and measured 10 traits of them with digitizer. Then it was observed that a few multicellar hairs were grown in Kunugi leaves and stellate hairs were grown thickly in Abemaki leaves. As a result, the classification of the two species and middle type (Abekunugi) of them was indicated based on their hair types. But we were not able to clear differences between these species from the traits of their leaves.

A simple method of rearing of the Japanese pine sawyer, Monochamus alternatus Hope (Coleoptera: Cerambycidae) on an artificial diet is proposed. The diet is composed of a commercially available artificial diet used for the silkworm, Bombix mori (Silkmate 3M(R); Nippon Nosan Kogyo Co.), milled fresh inner bark of Japanese red pine, dried yeast and tap water. The masses of each ingredient required for 150 beetles (=150 rearing bottles) are 2kg, 1kg, 20g and 1500ml, respectively. The bottles were autoclaved for 10 min. (1.2kg/cm^2, 120℃). In the case of inoculated first and second instar larvae from Kyoto and Ibaraki, Japan, these were reared at 25℃LD10:14 for five months after oviposition, chilled for two months at 10℃ constant darkness and then reared at 25℃LD16:8. One hundred and seventy five beetles from 210 inoculated larvae (84.8%) emerged an average 47.2 days after chilling.

The Japanese pine sawyer, Monochamus alternatus (Coleoptera: Cerambycidae), which emerges once a year and diapauses in its last instar in Japan, was reared under various thermal and photoperiodic conditions on an artificial diet. When reared under 25℃LD10:14 for five months before two months chilling under 10℃ and complete darkness, almost all the beetles (97.8%) pupated at 25℃LD16:8 after chilling. But when kept at 25℃LD16:8 for five or seven months before chilling, the propotions of pupation were 51.2% and 61.5% respectively. The low diapause termination was thought to be an adaption in order for beetles not to emerge within a year through the experience of unexpectedly low temperature in summer or early autumn. The propotion of pupation varied among the parents under these conditions. When reared under 25℃LD16:8 with LD10:14 intervening for two months at the fifth month after oviposition, no beetle emerged. Low temperature is therefore needed to terminate the diapause when reared under a long photoperiod.
