  • Aboveground biomass and structural characteristics of poisonous <i>Pieris japonica</i> shrub stands dominating under deer pressure

    Ichihashi, R; Katayama, A

    Canopy tree seedlings rarely grow in regions with overabundant deer in Japan, whereas Pieris japonica, a shrub species that is unpalatable to deer, has been expanding its habitat and occasionally forms dense pure stands in disturbed locations. Although this species could be the key to understanding vegetation structure and function under intense deer pressure, little information is available regarding the structural and functional aspects of P. japonica stands. Here, we examined aboveground mass (MA) and several structural parameters for 13 P. japonica stands of various developmental stages (3–64 years old as estimated from the number of growth rings of component plants); the stand MA and leaf area were estimated by developing relevant allometric equations for individual plants. The MA of P. japonica stands (≤50 Mg ha−1) were less than a fifth of that recorded for neighboring forests consisting of deciduous broad-leaved trees and conifers. Leaf area index (≤4.9 m2 m−2) and basal stem area (≤62 m2 ha−1, determined at 5 cm from the ground) of the stands reached the level comparable to tree forests, whereas canopy height (≤4.4 m) was much shorter and plant density (≥7,300 stems ha−1) was fairly high compared with those of average tree forests in neighboring regions. The stand structure lacked thick and long boles, resulting in low biomass accumulation in P. japonica stands. Thus, one possible consequence of the long-lasting deer pressure is the reduction of the carbon sequestration capacity to a fraction of that of the present forests.

  • Current status of Fagus crenata dominated forests and their understory vegetation in Kyushu

    Kyushu is the western and southern limits of beech (Fagus crenata) distribution in Japan, where Pacific-type beech forests are found in the mountains. Recently, overgrazing by deer has caused a decline in the forest understory, particularly the dwarf bamboo (Sasa spp.), causing concerns about forest degradation of the environment and ecosystems in Kyushu. However, few vegetation surveys of beech forests in Kyushu have been conducted since the early 2000s, when deer grazing became a prominent issue. This study aims to understand the present condition of beech forests in Kyushu by conducting vegetation surveys at 7 sites, and visually recording vegetation at 5 sites. We established five plots, each with a radius of 5 meters and centered around a selected beech tree, on each site, and measured basal area, the proportion of beech in basal area, tree density, sasa height, and sasa stem density within each plot. We found that sasa has disappeared from understory vegetation in some sites (Mt. Furusobo-san, Mt. Mukouzaka-yama, and Mt. Sanpou-dake) and that there is a large variation in sasa stem density in sites where sasa remained, indicating that the impact of deer grazing in beech forests was highly site-specific. Vegetation surveys including forest understory are important for monitoring the rapid changes occurring in forest environments in recent years.

    The number of Sika deer was recorded in Ashoro Research Forest, Kasuya Research Forest and Shiiba Research Forest in the Kyushu University Forests. Ashoro Research Forest has a cool temperate deciduous forest, Kasuya Research Forest has a warm temperate evergreen forest and Shiiba Research Forest has a warm temperate deciduous forest. The spotlight census was conducted for five years from 2017 to 2022 at three locations in the Kyushu University Forests. In the three forests of the Kyushu University Forests, the census courses of the 4 km and the 3.5 km were used in Ashoro Research Forest, 1.7 km and 0.5 km in Kasuya Research Forest, and 6.1 km and 2.8 km in Shiiba Research Forest.

    We investigated the first year damage caused by Japanese oak wilt which is a vector-borne disease transmitted by Platypus quercivorus in the Shiiba Research Forest, Faculty of Agriculture, Kyushu University. We found that 18 % of the Fagaceous trees in the study sites, excluding those of the genus Fagus, were damaged by Platypus quercivorus. The proportion of damaged trees per species was the highest for Lithocarpus edulis, but the mortality rate of damaged trees was the highest for Quercus crispula, raising concerns about significant changes in the forest ecosystem in the future. Differences in damage rates of individual tree species and tree DBH classes suggested that Platypus quercivorus may be selecting tree species and tree sizes. There is a possibility that Platypus quercivorus are migrating northward from the south side of the forest. It is necessary to observe the progress of the forest on the north side, which has not been damaged yet, and to study damage control methods and to restore vegetation after the damage has been controlled.

    To compare the performance of synthetic fiber nets and electric fences as wildlife prevention fences, we planted seedlings of Pieris japonica, Chamaecyparis obtusa and Quercus crispula in the 5 cm mesh net, 10 cm mesh net, electric fences, and control plots. Seedlings height and survival rate were recorded from 2015 to 2020. We also recorded the flora of these experimental plots in 2016 and 2021 to compare the changes of forest floor vegetation in the plots. Pieris japonica grew well in the control plot and most of the individuals survived. Tree height of Chamaecyparis obtusa was highest in the electric fence, and the survival rate was over 90 % in the 5 cm mesh net. The average height of Quercus crispula was only 87 cm and the survival rate were only 33 % due to shade by herbaceous plants. A total of 52 herbaceous species and tree seedlings in the forest floor were observed in 2016, and this number increased to 81 in 2021. In addition, seedlings of Pinus densiflora, Quercus crispula, Hydrangea paniculata and other pioneer species became established, suggesting that enclosing the floor of forest gap with fences may lead to the regional compensatory vegetation.

    温帯生つる植物の通導・水利用の特性、特に冬期の寒冷に対する反応は、つる植物の世界的な地理分布パターンにも深く関わる重要形質と目されているが、情報は極めて少ない。本研究ではつる植物の通導特性を探る第一歩として、九州大学宮崎演習林に優先する樹木9種 [環孔材種:ミズナラ、クリ。散孔材・根圧種(春の展葉前に幹に開けた穴から水滲出を確認):ミズキ、ミズメ、ヒメシャラ、アカシデ、コハウチワカエデ。散孔材・根圧未確認種:ブナ、ホオノキ]、つる植物4種(環孔材種:フジ、ツルウメモドキ。散孔材・根圧種:サルナシ、マツブサ)を対象に、茎切片の通導度と、茎基部の樹液流速の測定を行い、その季節変化の様子を解析した。

    夏期の茎通導度(specific conductivity)は、樹木では2~6 kg s-1 m-1 MPa-1の範囲であったが、つる植物の環孔材種は30 kg s-1 m-1 MPa-1前後、散孔材種は80 kg s-1 m-1 MPa-1前後と、極めて高い値を示した。つる植物は遠位の葉面積が大きいため、葉面積あたりの値を計算すると、環孔材つる植物では樹木と同程度、散孔材・根圧つる植物種では2倍程度となり、樹木との差は小さくなった。冬期(2月初旬)、つる植物と散孔材樹種は通導機能をほぼ完全に失っていた一方、散孔材樹種の多くは、夏期の50%以上の通導機能を維持していた。展葉期(5月)、樹木・つる植物とも環孔材種では未だ通導度が低かった(夏期の10~20%程度)一方、その他の種では、夏期と同様の通導機能を示した。樹液流の測定からも同様の季節変化の様子が確認された。以上、これまでのところ、夏期の高い茎通導度など、つる植物に共通する特徴が見つかる一方、寒冷に対する反応において、環孔材的に当年の導管のみに通導を頼るか、展葉前に根圧を用いて通導を回復させるかという、異なる対処の仕方が樹木とつる植物の双方に存在することが明らかになった。

    つる植物は熱帯から温帯にかけて密度・種数が大きく減少するが,これは「つる植物の通導構造が凍結に弱く,氷点下の気温がその成長を制限するため」と考えられている.そうであれば,温暖化に伴う冬期の気温上昇により,温帯林においてもつる植物の影響が顕在化してくる可能性があるが,これまでこの仮説に対して充分な検証は成されていない.本研究では,暖温帯,冷温帯の2地点において,つる植物と樹木の通導・水利用に関する基本特性とその季節変化を評価する.つる植物と樹木の比較,また寒冷の程度が異なる2地点の比較を通し,氷点下の環境が特につる植物の通導機能に対して阻害的に作用しているかを検証する.

  • Does winter freezing affect more on the hydraulic and photosynthetic functions of temperate lianas than trees?

    This study aimed to elucidate the hydraulic features, especially their responses to winter freezing, for liana and tree species in a cool-temperate forest. Measurements of the seasonal patterns of sap flux and stem hydraulic conductivity, and the extent of root pressure generated prior to bud break revealed that some species rely only on current-year xylem for water conduction whereas some others restore the hydraulic function of older xylem by means of root pressure in early spring. Both types of hydraulic strategies were found in both lianas and trees and striking differences were not found in responses of stem hydraulics to freezing between both groups.

    竹林の炭素固定量はどれくらいなのか?、それは将来の温暖化に伴ってどれくらい変化しうるのかという疑問に答えることを目標として、1)竹林における炭素吸収量および放出量の年々変動の測定と変動要因の解明、2)竹林の炭素吸収量および放出量の変動特性を再現する炭素固定量算定モデルの構築、を行う。また、3)そのモデルと広域メッシュ化情報を利用し、広域の竹林の炭素固定量の算定と将来予測を行う。
