Given the recent increase in demand for larch as lumber, it is necessary to assess the impact of fraying damage on larch wood and the frequency and change over time in occurrence of such damage.  In this study, we investigated the presence or absence of fraying scars caused by sika deer on all trees in two planted larch stands in the Okutama Practice Forest.  In addition, we attempted to elucidate the trend over time in fraying damage incidence in the study area by assessing the year of annual tree rings containing scares by dendrochronological method.  The results showed that fraying scars were observed in 190 of the 650 trees examined (29% examined trees).  Core samples were collected from 98 of these scarred trees.  Although scars could not be distinguished or were difficult to distinguish in the xylem of some samples due to rot, we were able to perform measurements for 74 trees (104 scars).  Larch trees with scars were found dating back to the 1970s.  The number of trees with scars increased in the 1980s and reached a peak in the 1990s.  Although the number has since declined, at present, new scarring continues to appear at an essentially constant rate.  The observed trend was consistent with trends reported in other studies on forest damage caused by sika deer in the Okutama area.","subitem_description_type":"Other"}]},"item_1_description_13":{"attribute_name":"レポート・講演番号","attribute_value_mlt":[{"subitem_description":"E","subitem_description_type":"Other"}]},"item_1_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"3","subitem_description_type":"Other"}]},"item_1_description_2":{"attribute_name":"ページ属性","attribute_value_mlt":[{"subitem_description":"P","subitem_description_type":"Other"}]},"item_1_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_1_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00164184","subitem_source_identifier_type":"NCID"}]},"item_1_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京農業大学地域環境科学部森林総合科学科"},{"subitem_text_value":"東京農業大学地域環境科学部森林総合科学科"}]},"item_1_text_7":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Bioporduction and Engineering, Faculty of Regional Environment Sience, Tokyo University of Agriculture"},{"subitem_text_language":"en","subitem_text_value":"Department of Bioporduction and Engineering, Faculty of Regional Environment Sience, Tokyo University of Agriculture"}]},"item_1_title_3":{"attribute_name":"論文名よみ","attribute_value_mlt":[{"subitem_title":"ジュモク　ネンリン　ネンダイガク　テキ　シュホウ　ヲ　モチイタ　ニホンジカ　ニ　ヨル　ツノコスリ　ショウガイ　ハッセイネン　ノ　トクテイ　―オクタマ　エンシュウリン　ニ　セイイク　スル　カラマツ　ニ　ツイテ―"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"桃井, 尊央"},{"creatorName":"モモイ, タカオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"4235","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大林, 宏也"},{"creatorName":"オオバヤシ, ヒロヤ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"4236","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Momoi, Takao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4237","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohbayashi, Hiroya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4238","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-07-31"}],"displaytype":"detail","filename":"65_19.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"65_19","url":"https://nodai.repo.nii.ac.jp/record/827/files/65_19.pdf"},"version_id":"e5fe5672-4ba5-4f5d-a8f1-989fb9a59fde"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"樹木年輪年代学的手法","subitem_subject_scheme":"Other"},{"subitem_subject":"ニホンジカ","subitem_subject_scheme":"Other"},{"subitem_subject":"角こすり傷痕","subitem_subject_scheme":"Other"},{"subitem_subject":"カラマツ","subitem_subject_scheme":"Other"},{"subitem_subject":"奥多摩","subitem_subject_scheme":"Other"},{"subitem_subject":"Dendrochronological method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Cervus nippon","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fraying scars","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Larix kaempferi","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Okutama","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"樹木年輪年代学的手法を用いたニホンジカによる角こすり傷害発生年の特定─奥多摩演習林に生育するカラマツについて─","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"樹木年輪年代学的手法を用いたニホンジカによる角こすり傷害発生年の特定─奥多摩演習林に生育するカラマツについて─"},{"subitem_title":"Use of Dendrochronological Method to Date Fraying Caused by Sika Deer ─On Japanese Larch in Okutama Practice Forest─","subitem_title_language":"en"}]},"item_type_id":"1","owner":"3","path":["188"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-07-31"},"publish_date":"2020-07-31","publish_status":"0","recid":"827","relation_version_is_last":true,"title":["樹木年輪年代学的手法を用いたニホンジカによる角こすり傷害発生年の特定─奥多摩演習林に生育するカラマツについて─"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-19T07:43:43.377263+00:00"}
