MOTOBE, Akari and HIOKI, Yoshiyuki: A case study on goal re-setting and forestation approach for a tree planting event Abstract: Many tree-planting events aim to create forests without a certain vegetation type as a target. For such planted “forest”, re-setting a clear target and finding an appropriate approach to reach that target is required. In this case study, we discuss an approach to re-set the target vegetation type at a factory’s tree-planting event area, in Tottori prefecture, Japan. The species composition and structure of surrounding climax and secondary forest were compared to those of the planted “forest”. Consequently, the Fagus crenata forest mixed with Betura grossa and Quercus crispula was identified as the long-term goal for the planting site. Additionally, tracing species composition between the climax and secondary forest was considered as an appropriate approach with which to set this goal.
Key words: forest planted by planting event, target vegetation, re-setting, approach, species composition, structure 1. ࡣࡌࡵ ㏆ᖺ㸪᳃࡙ࡃࡾࢆ┠ⓗྛᆅ㸪ྛศ㔝࡛᳜ᶞάືࡀάⓎ ⾜ࢃࢀࡿࡼ࠺࡞ࡗ࡚࠸ࡿ12)ࠋ୰࡛ࡶ㸪⮬↛㏆࠸ᶞᯘࡢ ⏕ࢆ┠ⓗࡋࡓ㸪ᕷẸཧຍᆺࡢ᳜ᶞ࣋ࣥࢺࡣ㸪ཧຍ⪅ࡢ⎔ ቃព㆑ࡢྥୖࡀぢ㎸ࡲࢀ㸪CSR άືࡢ୍⎔ࡋ࡚ྲྀࡾධࢀ࡚ ࠸ࡿᴗࡶከ࠸ࠋ ᳜ᶞ࣋ࣥࢺࡼࡿ᳃࡙ࡃࡾࢆᡂຌࡉࡏࡿࡓࡵࡣ㸪ࡲࡎ㸪 ┠ᶆࡑࡇㄏᑟࡍࡿ㐣⛬ࢆ᫂☜ࡘヲ⣽タᐃࡍࡿᚲせࡀ ࠶ࡿࠋࡲࡓ㸪⟶⌮ẁ㝵࡛ࡣ㸪ࣔࢽࢱࣜࣥࢢࢆ⾜࠸㸪ࡑࢀᇶ ࡙࠸࡚᳜⏕⟶⌮᪉ἲࡢᨵၿࢆ⾜࠺ࡇࡀᮃࡲࡋ࠸ࠋ᳜ᶞ࣋ ࣥࢺ᭱ࡶࡼࡃ⏝࠸ࡽࢀࡿᡭἲࡋ࡚㸪ᶓᅜ❧Ꮫࡢᐑ⬥ ྡᩍᤵࡽࡼࡿ͆ᐑ⬥᪉ᘧ͇7)ࡸ㸪࢚͆ࢥࣟࢪ࣮⥳͇ 12) ࡀ࠶ࡿࡀ㸪ࡇࡢᡭἲࡼࡿ᳃࡙ࡃࡾࡢ┠ᶆࡣ₯ᅾ⮬↛᳜⏕࡛ ࠶ࡾ㸪᳜᱂ࡢ≧ែࡽ┤᥋┠ᶆ᳜⏕฿㐩ࡍࡿࡇࢆ┠ᣦ ࡋ࡚࠸ࡿ㸦௨ୗ㸪ࠕ┤㐩ᆺࠖ㸧ࠋᐩኈᒣ㯄࠾ࡅࡿ͆ࣃࢵࢳ ᳜᱂ἲ͇19)ࡶྠᵝࡢ┠ᶆㄏᑟ㐣⛬ࢆࡶࡗࡓᡭἲࡢ୍ࡘ࡛࠶ ࡿࠋ୍᪉࡛㸪͆⏕ែᏛⓗΰ࣭ΰ᳜ἲ͇13)ࡸ͆⮬↛㓄᳜ᢏ⾡ ͇17)࠸࠺ᡭἲࡶᏑᅾࡍࡿࠋࡇࡢᡭἲࡣ㸪᭱⤊ⓗࡣᴟ┦ᯘ ࡸ࿘㎶⮬↛᳜⏕ࢆ┠ᣦࡍࡀ㸪ࡲࡎࡣඛ㥑ⓗ࡞᳜⏕ࢆᙧᡂࡋ㸪 ࡑࢀࡀ㑄⛣ࡍࡿࡇ࡛┠ᶆ᳜⏕ㄏᑟࡍࡿࡇࢆ┠ᣦࡋ࡚࠸ ࡿ㸦௨ୗ㸪ࠕ㑄⛣ᆺࠖ㸧ࠋࡇࢀࡽࡢ᳜᱂ᡭἲ࡛ࡣ㸪࣐ࢽࣗ ࣝࡢసᡂ 7,12,13)ࡸ㸪᳜᱂ࡽᩘᖺᚋࡢࣔࢽࢱࣜࣥࢢ࣭ホ౯ 11,14,15,20)ࡀ⾜ࢃࢀ࡚࠸ࡿࠋ ࡋࡋ㸪ୖグࡢࡼ࠺࡞ᡭἲᇶ࡙ࡎ㸪᳜᱂ᚋᨺ⨨ࡉࢀ࡚ ࠸ࡿ᳜ᶞ࣋ࣥࢺࡼࡿ᳃࡙ࡃࡾࡢࡶᑡ࡞ࡃ࡞࠸ࠋࡇࢀ ࡣ㸪᳜ᶞ࣋ࣥࢺࡑࡢࡶࡢࡀ⮬ᕫ┠ⓗࡉࢀ㸪┠ᶆ᳜⏕ࡸ᳜ ⏕ィ⏬ࡀ᫂☜࡛࡞࠸ࡲࡲ᳜࠼ࡽࢀࡓࡓࡵࡔ᥎ᐹࡉࢀࡿࠋ ࡑࡇ࡛ᮏ◊✲࡛ࡣ㸪㐣ཤ 10 ᖺ㛫ࢃࡓࡗ࡚᳜ᶞ࣋ࣥࢺ ࡀ⾜ࢃࢀࡓ㫽ྲྀ┴ࡢ᳜ᶞᯘ࠾࠸࡚㸪┠ᶆ᳜⏕ࢆ᫂☜タ ᐃࡍࡿ᪉ἲ㸪タᐃࡋࡓ┠ᶆ᳜ᶞᯘࢆㄏᑟࡍࡿ㐣⛬ࡘ࠸ ࡚ⓗ᳨ウࡋࡓࠋ ᮏ࡛⾜ࢃࢀࡓ᳜ᶞ࣋ࣥࢺࡢᙜึࡢ┠ᶆ᳜⏕ࡣ㸪Ẽೃ ⓗᴟ┦࡛࠶ࡿࣈࢼᯘ࡛࠶ࡗࡓࠋࡋࡋ㸪᳜᱂ᙜࡣヲ⣽࡞᳨ ウࡀ⾜ࢃࢀ࡚࠾ࡽࡎ㸪᳜᱂ᶞ✀ࡀࣈࢼᯘࡢ✀⤌ᡂࢆ㐺ษ ᫎࡋࡓࡶࡢ࡞ࡗ࡚࠸ࡿ࠺ࡣ࡛᫂࠶ࡗࡓࠋࡑࡇ࡛㸪 ᩥ⊩ㄪᰝࡸ࿘㎶ᶞᯘࡢㄪᰝࢆᐇࡋ㸪ᐇ⌧ࡍࡁࣈࢼᯘࡢ✀ ⤌ᡂࡸ᳜ᶞᯘࡢ✀⤌ᡂࡢ┦㐪ࢆ᫂ࡽࡍࡿඹ㸪ࡇࡢ
