For the purpose of analysis and evaluation on the ecosystem’s cultural services of urban green-spaces, several field researches (tree census, vegetation-landscape investigation and hemispherical sky photography) were carried out on streets and parks existing in “Yokohama-Minatomirai 21”, and those obtaining data were analyzed statistically. The vegetation-landscape units (type and subtype) distinguished by a table manipulation for the urban green-spaces classification were divided into four main groups by a correspondence analysis. The landscape elements which would characterize each main group were identified by an independence test and a residual analysis. Based on those statistical analyses, we have evaluated about the positive psychological effect by which the urban green-spaces bring people “comfort” and “relief” which are a part of the cultural services. Moreover, the means to create the urban green-spaces, by which the fascination of regional landscapes would upgrade, were proposed.

く影響される(Soga et al. 2016a, b, 2018;Hosaka et Abstract: In this study, our aim was to quantitatively evaluate the habitat of the terrestrial firefly Luciola parvula in the Shonai region of Yamagata Prefecture, Japan. Sixteen survey sites with differing topography and types of forest vegetation were set around Mt. Takadate. We counted the number of individual adult fireflies at each survey site between June and July 2018. The relationship between the number of adult individuals and topographic position index (TPI), an indicator of topography, and the forest vegetation types (broad-leaved forest, pine forest, or cedar forest), was analyzed by the generalized linear mixed model (GLMM). In addition, the amount of food resources (land snails and soil animals) considered important during the larval stage was surveyed in October 2018, and the survey of soil water content was conducted in June and October 2018. The relationships between food resources and soil water content and environmental conditions (i.e. TPI and forest vegetation types) were analyzed by the generalized linear model or GLMM, respectively. The result of the model revealed that TPI is related to the number of adult individuals, and that the population tends to be larger near the valley. Moreover, it was shown that the valley tends to have a large number of land snails and a high soil water content. It is therefore suggested that the environment with a large number of individual adult fireflies was a suitable habitat for the larvae of fireflies. This may be related to the poor ability of adult females and larvae to migrate.
(Soga et al. 2016a, b, 2018;Hosaka等)摘要:本研究旨在定量评价日本山形县正奈地区陆生萤火虫(Luciola parvula)的栖息地。在高馆山周围设置了16个具有不同地形和不同森林植被类型的调查点。我们在2018年6月至7月期间计算了每个调查地点成年萤火虫的数量。采用广义线性混合模型(GLMM)分析了成虫数量、地形指标地形位置指数(TPI)与森林植被类型(阔叶林、松林、杉林)之间的关系。此外，在2018年10月调查了幼虫期被认为重要的食物资源(蜗牛和土壤动物)数量，在2018年6月和10月进行了土壤含水量调查。采用广义线性模型和GLMM分别分析了粮食资源与土壤含水量和环境条件(即TPI和森林植被类型)之间的关系。模型结果表明，TPI与成年个体数量有关，且在山谷附近种群数量往往较大。此外，研究表明，谷地往往有大量的土地蜗牛和高土壤含水量。因此，有大量成虫个体的环境是萤火虫幼虫的适宜栖息地。这可能与成虫和幼虫的迁移能力较差有关。

: As a consequence of increased urbanisation, floods threaten inhabitants of various cities in Japan. Although a conventional way of treating urban flooding is to construct sewage systems, alternative approaches have to be developed because of their expense in the context of the current financial crisis. Rain gardens have recently been recommended as a best management practice for the treatment of stormwater runoff in Northern European countries, the USA, etc. While demand for rain gardens has been increasing in Japan, there is a lack of knowledge about policy planning for the development of rain gardens. This present study aims to 1) visualise a possibility for the development of rain gardens as a map and evaluate its effect in terms of storm water management in most urbanised area “ Delta Zone ” in Hiroshima-City, Japan, 2) discuss a method for policy planning for mainstreaming rain gardens as a kind of green infrastructure. By use of GIS technology, the areas under the conditions (elevation < 5.0 m, slope angle < 1.1 degrees and GWL < -2.0 m) were selected as potential areas for rain garden installation. Next, 1) green spaces, 2) sandy spaces, 3) car parks on the potential areas were identified because those spaces are easier to install rain gardens than building and road areas. As s result, it was indicated that “ Delta Zone ” could obtain a rainwater infiltration function to treat 20 mm/h stormwater event if only 10 % of those spaces turn into rain gardens. In addition, a practical scenario to mainstream rain gardens in Japan was discussed.

: I evaluated moso bamboo Phyllostachys edulis growth and wild animal activity in a bamboo stand in Kyoto, western Japan, during 2016-2019. The aboveground biomass increment of the moso bamboo stand, an index of bamboo growth, was consistently negative throughout the study period, presumably due to limitations on the production of new bamboo shoots. Using camera traps, I frequently observed damages to moso bamboo shoots by wild boar Sus scrofa and sika deer Cervus nippon between March and May, which led to growth failure for new bamboo shoot production. This report highlights the possibility that wild animal activity may inhibit moso bamboo growth in naturalized moso bamboo stands in Japan.
