Several studies were performed on individual scale tree species classification, tree crown extraction, and tree stem extraction in broadleaf forests using UAV aerial imagery. In the tree species classification, object-based image classification was performed for natural forests consisting mainly of beech forests, and classification was successfully performed with a Kappa coefficient of 0.726. For individual scale crown extraction, we tried two methods: the valley following method and the lidR package. The accuracy of tree crown extraction was verified for each. For tree stem extraction, UAV aerial photography was conducted in a beech stand during the leaf-off season, and the reconstruction of tree stems was evaluated for several parameters. The direction of the camera (camera angle) was also considered in the tree stem extraction, and the reconstruction rate of tree trunks was higher when the oblique view was employed in addition to the nadir view.

In the mountainous heavy snowfall region, we examined the possibility of sustainable beech forestry, due to effective estimation of beech volume in stand scale, measurement of available beech round timber from stand volume, criteria for sustainable harvest of selective logging and thinning, furthermore, ecological character.
On GIS system, we cut the study area of 700 hectares into the mesh size of 50 meters and then estimated stand volume in each mesh from an equation with tree crown area measured on the aerial photos. Following the total stand volume, we proposed a group selection system in an analogous manner to primeval forests recurring in cycle of one hundred years. Intense thinning should be effective for growing sufficiently of the high dense seedlings regenerated in advance. We also showed that the trees with hollows should be left for nesting site as much as possible in a harvest stand for the biodiversity forest management.

At a sandy shore in Sado Island, density of small crustaceans once declined by the construction of a new road along the shore, but the density increased afterwards. Survey on sandy shores along the Japan Sea coast of Honshu revealed 28 taxonomic groups and 7 types of community. Relationships between the occurrence of the communities and environmental factors were investigated with an aid of GIS data processing. As a result, three vertical zones were generally recognized. Statistical models did not detect any significant effects of artificial constructions (e.g. seawalls) on the occurrence of the shore communities. But, an examination using BIOLOG plates indicated that activity of bacteria was different between the shores with different land-use.

We propose a new method of extracting plantation boundary through multi-temporal image analysis using past aerial photos which have been taken by the Forestry Agency and the Geographical Survey Institute, Japan. Clear cut and planted sites were extracted with the second principal component of the principal component analysis of a two-year composite image of brightness or DSM data. This proposed method presented the possibility to delineate the boundary of the plantation.
We focused on local maximum filtering method as one of the extraction methods for single tree apex, and performed the stand density estimation of Japanese cedar plantation using GeoEye-1 panchromatic image (0.5-m spatial resolution). In this paper, we examined about the effect of filter size of maximum filter or low-pass filter for noise reduction on stand density estimation.

):Density of Haustorioides japonicus in summer shows a spatial variation. Recruitment of juveniles caused this variation, but the other life history characteristics did not affect it. Location of sandy shores including slope of offshore seafloor could explain this variation, while analyses on food web structure and genetic composition could not. So, these results suggested that the spatial variation in production of H. japonicus was due to the effect of shore environment on its early life stage.

To complete a restoration scenario for the resettlement of the crested ibis, we created the potential maps for predicting prey biomass, nesting habitat, and foraging habitat of ibis, using generalized linear model. By reflecting this information on the Sado city's strategy for improving biodiversity, a system that verify effectiveness of restoration scenario and modify it sustainably could be built up. Next, in order to evaluate whether re-introduced population will persist for 50 years on Sado Island, population viability analysis(PVA) was conducted using population parameters of wild population in China and revealed that establishment of the re-introduced population on Sado island will be difficult under current fragile reproduction.

The objective of this research is to evaluate new functions of rubber plantations as forest and wood resources, not only as cash crop and its by-product. We first clarified importance of rubberwood in wood markets in Malaysia, Thailand and Cambodia. And we evaluated wood production and carbon uptake functions, through developing biomass and stem volume equations and investigating wood quality.Finally, we examined interactions between wood and latex production, and climate factor, finding clear trade-off of wood and latex production in rainy season.

The object of the research was to establish monitoring and modeling systems of forest dynamics and hydrological and material cycles based on the observations in the four university forests in different climate, and establish the process-based models for evaluating and forecasting the effects of climate changes. Seven monitoring plots for long-term ecological research were set, and the forest data of various forest types were archived by the monitoring using the methods used in the Monitoring 1000 Project of Ministry of Environment Some remote sensing techniques for monitoring forest dynamics were also established. Evapotranspiration process studies based on the sap flow measurement were conducted in various forest stands (Japanese cedar, Japanese cypress, oak, bamboo). Some features of evapotranspiration processes of each forest were obtained, and the guides to measure sap flow for each forest were proposed. By investigating the reported results of long-term water budget and flux measurements, the effects of growth, density and types of forests on the catchment water budget were clarified, and some practical process-based models of evapotranspiration were proposed. The monitoring of hydrological and material cycles was conducted in the serpentinite watershed where these studies were rarely conducted in Japan. The results suggested that the common processes found in other watersheds could not always be applied to the other watershed where the bedrocks were different The results also indicated that the run off process (suspended / soluble) of nitrogen and phosphorus were considerably different depend on the discharge, and proposed the practical models to estimate the discharges of these nutrients. Hydrological process-based model was made, and effects of climate changes on the discharge from the forest catchment in the snowy region were analyzed. Although these results were not fully integrated, many new data, information, techniques, and models obtained in this project will contribute to the researches on global warming.

National Forest Inventories (NFIs) have been carried out in many countries , and historically, NFIs were very much oriented toward describing state and change of forests with regard to timber production . Over recent decades, there is an increased demand for information on non-productive functions of forests due to the requests of policy makers and the public's perception of forests . Quality Assurance (QA) is essential in long-term and large-scale environmental monitoring programs to ensure a documentation of quality of the field data and allow a data quality evaluation. However, there has been very limited information of current level of NFI data quality over the world.
We evaluated data quality of Japanese National Forest Inventory, which had started in 1999 and had not carried out quality assurance program. Forty eight plots in four prefectures were remeasured by a control team, making careful and unhurried measurements. The paired data between field teams of each prefecture and the control team were evaluated, including two tree-level valuables (DBH and total height) and seven plot-level valuables (tree count, tree species richness, understory vegetation species richness and 4 of topographic condition). As compared to the control team, all field teams of each prefecture tended to significantly underestimate all of the continuous valuables. Most variables had larger variability as compared to the published literature, without achieving measurement quality objectives adopted in other monitoring programs. The findings of consistent bias and large variation of the field team measurements call for urgent implementation of quality assurance (QA) program (extensive field training and regular remeasurement) to improve data quality in Japan as well as countries without QA program. This study also suggested to promote international comparisons of data quality data to standardize the quality level at global scale.

本研究は対象地を九州本島に限定し,伐採地の時間的・空間的出現動向とシカ生息・被害分布について10〜30年の時間スケールからその関連性を検討することを目的としている。また,九州におけるシカ生息分布域の変化について,その特徴を各種空間データから検討した。今年度は後者について取り組んだ。
まず,環境省(環境庁)の野生動物保護調査に関するデータ(第2回自然環境保全基礎調査(1980),第6回自然環境保全基礎調査(2004))からシカ生息の分布拡大が起こった地域,シカ生息のみられなくなった地域など4タイプのシカ生息分布変化パターンを規定し,標高値,土地利用などの集計を行った。その結果,シカの生息が元々確認される地域は高標高域に存在し,新たにシカの拡大がみられた地域は低標高域にあることが示された。シカの拡大が森林率の高い高標高域から,周辺の低標高域にむかったことがはっきりした。
シカの分布拡大のみられた地域,みられなかった地域の特徴をみるため,ロジステック回帰分析と分類樹(Classification tree)による解析を試みた。その結果,ロジステック回帰分析では,天然林面積,森林面積,標高が説明因子として採用された。また,分類樹の結果においても天然林面積,標高が有効な因子として選択された。二つの異なる統計的アプローチにおいて,天然林面積,標高が採用されたことから,これら二つの因子がシカの分布拡大を説明する上で重要なものであることがわかった。

Woodfuel is essential for daily life in many countries, but there have not been enough information on effects of woodfuel consumption on forest condition. The objectives of this study were to assess effects of woodfuel consumption on quantity (biomass) and quality (biodiversity) of forests and to propose some strategies for sustainability of both woodfuel use and forest resources, in Kampong Thom Province, Cambodia as a case study site.
First, we investigated the relationships between woodfuel consumption and forest biomass increment for each of three village groups ; remote area, populated area and intermediated areas, using GIS. The woodfuel consumption rate was estimated by interview surveys and the forest biomass increment was estimated using data of forest inventory and permanent sample plots (PSPs). The result showed that woodfuel consumption was larger than biomass increment in the area within 3 km from the National road.
Second, we did more detailed interview surveys for 200 households to assess differences in woodfuel consumption patterns among three village group. The results showed that people do not cut and use trees with DBH more than 30 cm for firewood and they collect firewood also in non-forest area. Considering these interview results, we re-assessed the balance between woodfuel supply (increment) and demand (consumption)
Third, to estimate forest biomass in details, we did re-measurement for 32 PSPs in Kampong Thom Province and for 20 PSPs in Koh Kong Province, and we did establish and re-measure 15 new PSPs in regrowth forest in Kampong Thom Province The results from these measurements were incorporated in the above re-assessment.
Forth, we examined the relationship between stand structure and species diversity of forest inventory plots and human population density within different distance from the plots. The result showed that tree density, stem volume and biomass had negative correlation with population density with 5 km from the plots.
Finally we measured stand structure in forests that local people actually recognized as suitable sites for firewood collection, and we clarified which species local people preferably selected

大分県に分布している放棄地の位置・立地条件の把握,および現植生状況の調査ならびに周辺森林の現地調査から,放棄地の立地条件と森林回復状態を同時に把握解析することで,再造林放棄地の森林機能問題(水土保全機能の低下等)の真偽を明らかにすることである。具体的には,以下の通りである。(1)放棄地の立地条件を解析し,立地的によい場所が放棄され森林資源の減少につながるのかを明らかにする。(2)放棄地の植生調査から,造林をしないことで本当に植生が回復しないのか,斜面崩壊などが実際に発生しているのかを明らかにする。(3)放棄地は年数の経過にともなう植生遷移の状況を明らかにする。
(1)については,林道から近い比較的立地的によい場所が放棄されている傾向があった。(2)(3)については,放棄地の現地調査を行い,すべての放棄地で植生の回復を確認した。さらに植生の回復状況を分析して,比較的クラスター分析の結果,全75プロット(1プロットは上層に植生が見られなかったことから,解析から除外)を7群に分類することができた。各分類群は共通主要樹種により,シロダモ群,アラカシ群,クサギ群,カナクギノキ群,クマノミズキ群、アカメガシワ・ヌルデ群、その他群であった。また,遷移の初期段階で先駆性樹種が優占する群と萌芽再生によって植生が回復している群があること,また放棄年数が長くなると先駆性樹種が優占していた植生群が徐々にアラカシなどの二次林優占樹種が優占する植生群に変化することは明らかとなった。
以上のように,放棄地における植生の回復は順調であり,斜面崩壊の危険性,水土保全機能の低下について,さほど大きな心配はないことがわかった。

本研究代表者は、不健全状態にある針葉樹人工林を各地域本来の広葉樹天然林へ逆誘導する森林経営システムとして、画伐方式を基本とした「等高曲帯状画伐システム」の基本設計を終了した現状下にある。この基本設計を現地に適用可能な森林経営システムとして詳細設計するために、このシステムの適用可能性を大きく左右するキーポイント、すなわち等高線に沿った等高曲帯状伐区の画伐による伐出作業が経営上支障無く実行可能か否かを検証するのが本研究の目的である。
今年度は、対象として霧島屋久国立公園内のヒノキ人工林で、今後の取り扱い問題の緊急度が高まった霧島国有林のヒノキ若齢人工林を中心に次のような研究を行った。1)帯状伐区の設定:研究対象地のヒノキ若齢人工林に、帯長(等高線に沿った長さ)と帯幅(落水線方向の幅)が異なる複数個の等高曲帯状伐区を設定するために地形測量を行った。2)等高曲帯状伐区内および周辺林分の立木調査:各等高曲帯状伐区内の立木を、伐区内に侵入した広葉樹を含めて調査し、対象林および周辺林分の林分構造と種構成を明らかにした。3)対象地域内の諸データによる施業・搬出方法の解析:対象地域内の地形、林道データならびに諸条件下における搬出に関する資料を収集した。
その結果、ヒノキ人工林に接している保護樹帯が、遺伝資源が豊富な天然林と同様の林分構造を示して母樹となりうる樹木が存在し、かつ保護樹帯内ではモミと広葉樹の更新が継続的に行われていることがわかった。さらに、周辺林分の調査から、アカマツとツガについても光条件によっては更新可能であることもわかった。よって、画伐によって光環境の改善をすることで充分に更新可能で、天然林への逆誘導に関しては、自然・地形条件的には伐出作業も含めて実行可能であることが明らかとなった。

In April 1972, an experimental management system for Japanese oak (Quercus mongolica var. grosseserrata) was established in a natural Japanese oak forest, approximately 200 ha in area, in the Kyushu University Forest in Hokkaido. The management system was imposed by dear-cutting system in tongue-shaped blocks surrounded by shelterbelts. Rotations were 150 years and cutting blocks for staggered annual cutting were set up. The natural stands containing these blocks have been managed by a silvicultural process designed to produce high-quality timber from Japanese oak. The results obtained for 30 years between 1972 and 2001 (the first, second and third periods) are follows;.
1) The number of first-year oak seedlings established by regeneration process per ha varied widely-from 5,000 (in 2001) to 133,000 (in 1974); it averaged 55,500. Such variation was due to noted variations in size of seed crop for natural forests of Japanese oak. 2) When the stands established by the regeneration process developed into near the 15-year-old stand, vertical stratifications were distinguished in the canopy on the same manner as the above established stands. 3) In the 15- to 22- year-old stand, the height of the upper oak trees seemed to be somewhat lower than the one of the upper trees progressing with wide variations. 4) In the established stands by the regeneration process from 15- through 29-year-old, whereas the DBH of the upper trees was varied between the 15- and 21-year-old stand, the diameter growth was nearly constant (approximately 5 mm per year) in the 21- through 29-year-old stands. 5) In the 35- to 57-yearold stand, the stand volume of the upper trees seemed to increase with an increase in stand age progressing with wide variations. 6) The average net annual revenue for the 30-year period was 335,000 yen, an amount calculated by subtracting the average cost per year (557,000 yen) from the average revenue per year (892,000 yen).
Investigating the profitability of this applied management system and improving its shortcomings will require that the experiment be continued over a long period.
