サカサマンネングサを用いた屋上緑化で,鉄鋼スラグ(成形スラグ,粒状鉄鋼スラグ)を用いてセダム欠損部分の補植を行い,補植最適時期の選定および粒状鉄鋼スラグの補植利用方法・効果を3ヶ年継続検証した。その結果,8月補植では発根率が約40 %と低い結果となったが,セダムのみで補植したものに比べ,粒状鉄鋼スラグ利用では3倍以上の発根率であった。5~7月補植では粒状鉄鋼スラグを設置し続けたことにより生存率も高く,粒状鉄鋼スラグ利用の可能性が示唆された。

“Ukiya no Sato” in the central part of the Kanto Plain, Japan, contains a mix of agricultural lands, such as paddy fields, and semi-natural grasslands, such as wetlands, and harvest mice (Micromys minutus) are found in both habitats. In this study, we investigated the nesting habits of harvest mice and the formation of semi-natural grasslands in this region to examine the conservation status of each. We observed many harvest mouse ball nests in the paddy fields on the plains, which were a long distance from the hilly and mountainous areas. It was inferred that the wetlands helped to maintain the mouse population through geographical and hydrological factors, as well as historical factors related to rural development. It was noteworthy that harvest mice in the study area particularly used the wetland species Carex dispalata as a nesting material and that the timing of leaf growth overlapped with the harvest mouse breeding season, indicating that this species was positively used as a nesting plant. From the viewpoint of conservation of the harvest mouse in the study area, it was considered necessary to shift to various plant communities in the wetland environment by improving the site condition closer to the wet side.

Yato (small valley with paddy field) in the urban area is important habitat for rural animals. Yato is a rural landscape made up of coppice forests, grasslands and farmlands. We discussed relations between the fauna and distribution of small rodents and land use of Yato landscape in the southwest Tama hills. As a result, Japanese large field mouse (Apodemus speciosus), house mouse (Mus musculus), brown rat (Rattus norvegicus) and harvest mouse (Micromys minutus) were observed by trappings and finding nests. Habitat utilization by these rodents were recognized as follows. 1. A. speciosus were dominant species in the survey area. They used all elements (coppice forest, farmland, grassland and paddy field) in Yato. It was considered that its main habitat was the coppice forest. 2. M. musculus utilized the farmland as its main habitat. 3. M. minutus were utilized the confined grassland. 4. R. norvegicus were captured only a few individuals at the farmland. When the mean range lengths were considered by the method of capture-recapture, it was clarified that A. speciosus had longer range lengths than any other species. It was suggested that landscape mosaics in Yato were important as rodent habitat. We concluded that managing land-use patterns of Yato is required to effectively conserve the rodents' diversity and their habitats.

<p><tt>カヤネズミは,里地では水田内,畦畔,耕作放棄地などの草地に営巣することが知られているが,我が国に一般的に見られる,草地の農的管理が十分に実施されている水田地域において,その営巣状況は不明な点が多い。本研究では,営農者を中心とした住民へのアンケートと営巣確認調査により,本種の営巣状況の把握を目的とした調査研究を実施した。農的管理が十分に実施され、草本類が伸長した畦畔や耕作放棄地が存在しない地域において本種の営巣が確認され,稲が成長した水田が本種の営巣環境として機能していた。</tt></p>

The changes in vegetation and small animal fauna were investigated in terraced paddy with stone masonry in the hilly and mountainous areas of northeast Kyushu where cultivation has been progressively abandoned. Grassland which includes Imperata cylindrical - Miscanthus sinensis community and Juncus effusu community was formed depending on the soil moisture in the extensively managed sites. With the progression of vegetation succession in the abandoned managed sites, the M. sinensis community has attained dominant status. Although frog species diversity increased in the mountainside terraced paddy, the abandonment of paddy field cultivation led to a decline of frog composition. Rana ornativentris and Rhacophorus schlegelii had continually inhabited the moorland vegetation since the open water bodies required for breeding in frogs were disturbance-created by the rooting behaviour of mammals. With regard to the mouse fauna, Apodemus speciosus had colonized the extensively managed sites, and A. argenteus was found in the abandoned sites characterized by dense coverage of tall plants such as M. sinensis. Though the Micromys minutus population had increased in the extensively managed sites subject to continued mowing, they were absent from sites that had been abandoned for approximately 15 years. It was clarified that the vegetation succession is dependent on both land-form and management practice, and that vegetation and soil moisture are important factors in determining small animal fauna.
