We investigated sediment transport rates during 6 months after clearcutting of a 100-year old sugi (<i>Cryptomeria japonica</i>) plantation in order to compare its spatial heterogeneity of sediment transport an uncut stand. After clearcutting, the extremely large sediment transport rate (STR) owing to the possible formation of `the water path' contributed to the higher coefficient of variation (CV) of STR compared to that in the uncut stand. To examine the factors affected the variations in STR, we classified the STRs of the clearcut stand into two categories (high and low STR) based on positive or negative deviation from the mean STR, and compared the forest floor cover by forest residues (woody debris and litter: FCR), litter movement rates, and slopes inclination between the categories. The low STR (negative deviation) had significantly higher FCR and smaller litter movement rates. STR showed a strong negative correlation with FCR. A decision tree analysis demonstrated that STR was low (negative deviation) when the FCR was less than 44.5%. These results suggested that the increase of STR due to the formation of water paths by skidding and the control of sediment transport by scattered forest residues contribute to the heterogeneous sediment transport in the clearcut stand.

This study aimed to examine the relationship between the ecosystem services of pollination offered by native honey bees (<i>Apis cerana</i>) and the distance to natural forests (as an indicator of landscape structure) in hyuganatsu (<i>Citrus tamurana</i>) orchards in Aya Town, Miyazaki Prefecture, Japan. Two statistical models were developed to predict the number of visits of native honey bees to hyuganatsu tree. The area-distaince model (AD-model) considered the area of natural forests and distance from natural forests and the area model (A-model) considered the total area of the surrounding natural forests, and the results of the two models were compared. The estimated parameters of both models suggested a positive effect of natural forests on pollination services. Further, the estimated effect of the landscape structure of the AD-model was greater than that of the A-model. These results suggested that the distance to natural forests is an important landscape factor for evaluating pollination services by native honey bees.

人工林における温暖化適応技術としての植栽樹種選択手法の開発
2015.04 - 2018.03
科学研究費補助金 基盤研究(C)
Authorship：Principal investigator
本研究の目的は人工林における温暖化適応策の一つとして、気候変動下においても持続的に温暖化緩和サービスを受けることができるように植栽樹種を選択するための情報を提供することである。将来的に予測される温暖化状況下では、場所によっては現在に比べて人工林の成長が低下し、温暖化緩和サービスが低下する懸念が示唆されている。これを回避する策として、伐採後に再造林する際に温暖化した環境により適した樹種へと植え替えるという選択肢がある。本研究では温暖化に適応した人工林の植栽樹種選択を科学的に判断することを目的とする。
