Objectives of this study are to make clear the vegetation structure of Hovenia dulcis community in the Korean Peninsula over ten mountains including 17 plots. The results were summarized as follows. Habitat of the community indicated that elevation ranged from 115 meter to 720 meter at the sea level, slope aspect in nearly all directions, bare rock from 0 to 90 percent, slope degree from 10$^{\circ}$ to 40$^{\circ}$, topography from valley to middle slope, the height of tree layer from 8m to 22m, the diameter at breast height from 12cm to 59cm and coverage from 65% to 95$\%$$\%$

This study is to suggest the technique of ecological park to compatible mountain ecosystem near the urban in Woomyeonsan Urban Nature Park. It was proposed to differential technique from established ecological park focused on changing the cognition of nature, wetland ecosystem protection and restoration, and studying by served sound leisure program(nature observation and experience, etc.), in compatible mountain and urban forest near the Urban. Firstly, to achieve this aim, it was carried out delicated research and analysis that were the angle of inclination, trail, fauna, actual vegetation, bird and insect, and then to selected nature trail course and analysis capability through it.. In the basic concept and plan, firstly to make park aid mark and foundation mark, and then to establish the detail programs, nature observation program, management and organization program. This site where valley and mountain coexist was highly capable but whole site was very steep, so usable area is very narrow. To make Woomyeonsan nature ecological park escape from the established wetland type, ecological park and the park of event have to use nature material and introduce visitor. To establish it as the Nature Culture observation park and reflect on forest, valley of Woomyeonsan was divided into three display places; Nature ecosystem Zone, Meditation Zone, Nature Culture experience Zone and Nature Culture observation Center. For satisfying with ecological park aid mark and foundation mark, it was proposed to settle management plan for volunteer control and organization composition.

Understanding how future climate conditions will be impact on the biodiversity and species composition is important, because biodiversity becomes more important in environment assessment. To understand the biological changes including diversity and species composition over time (temporal variation within a year), the species diversity and composition of ground beetles were investigated in two well-preserved areas in the Sobaeksan National Park using pitfall traps. In addition, relationships between ground beetles and environmental variables were studied by considering temporal variation. We collected 2,146 ground beetle specimens representing 45 species, and individual-based rarefaction curves indicated that similar species richness was found between Geumseon Valley (GV) and Namcheon Valley (NV). The Bray-Curtis matrix comparisons between study sites were characterized by similar ground beetles sample heterogeneity, while temporal variations in abundance, species richness, and ${\beta}-diversity$ of ground beetles showed rather difference over time according to location of study sites. In GV site, minimum temperature was selected as the best predictor for abundance, species richness, and ${\beta}-diversity$ of ground beetles, while those relationships in NV site were more complicated. In conclusion, our study suggests that understanding the different response of ground beetles to climatic variables related to local habitat conditions is important to predict the effect of climate change on biological communities.

백두대간 태백산지역의 백천계곡에 대해 삼림군집구조 분석을 실시하기 위해 50개 조사구를 설치하고, 식생조사를 실시하였다. TWINSPAN 기법을 활용하여 군락을 분리한 결과 신갈나무-소나무군락(I), 소나무-신갈나무군락(II), 당단풍-신갈나무군락(III), 박달나무-당단풍군락(IV), 그리고 층층나무군락(V)의 5개 군락으로 최종 분리되었다. 각 군락은 층위별 상대우점치 분석을 통하여 식생구조를 밝혔다. 연륜분석결과 백천계곡의 임령은 소나무림이 50~75년. 신갈나무림이 40년 내외로 밝혀졌다. 단위면적당(100$m^2$) 평균출현종수는 11.1$\pm$2.2종, 평균출현개체수는 74.6$\pm$28.1주였다. 흉고직경급별 분석을 포함한 이상의 결과로 식생천이를 예측한 결과 백천계곡은 소나무에서 신갈나무를 거쳐 층층나무, 박달나무 등의 활엽수로 전개될 것으로 판단된다

오대산 국립공원의 주연부 수종 및 식생구조를 밝히기 위하여 1995년 7월 1일-4일에 현지조사를 실시한 결과는 당므과 같다. 오대산 곡간부에 위치한 삼림주연부의 종구성은 삼림내부와 상이하였다. 종다양도, 종수, 수관피도 및 개체수는 주연부에서 임내로 갈수록 감소하였다. 병꽃나무는 온대기후대 전역의 주연부에서 경쟁력이 우수한 수종으로 나타났으며, 오대산 국립공원에서만 출현한 주연부 수종은 조회풀과 산조팝나무이었다.

Scutellaria tuberifera C. Y. Wu & C. Chen belonging to Lamiaceae, a species previously unrecorded for Korean flora, was collected streamside in the Andeok valley of Seogwipo-Si, on Jeju island. This species can be distinguished from others of Scutellaria from Korea by having rhizomes with leafless and branching stolons at the nodes, globose to ovoid tubers 5-7 mm in diameter at the terminal parts, and stems densely spreading pilose. Photos of the habit and illustration are provided.

The purpose of this study was to explain relationship between community structure and their environment variables in Mt. Hwaak. Samples were collected by 101 plots using ZM phytosociological method and followed by cluster, importance value and canonical correspondence analysis. The forest vegetation classified into 8 community types such as Pinus densiflora community, Berberis amurensis community, Betula ermani community, Betula schmidtii community, Larix leptolepis community, Pinus koraiensis community, Cornus controversa community and Salix koreensis community. Altitude was considered as the highest factor correlated to the community types. Berberis amurensis community and Betula ermani community were located in upper slope area of high elevation, Comus controversa community and Salix koreensis community in valley area, and Pinus densiflora community in ridge area, respectively.

The present study was undertaken in moist temperate forest of Mandal-Chopta area in the Garhwal region of Uttarakhand, India. The aim of the present study was to assess the physical properties of soils in relation to the forest structure and composition. Twelve forest types according to the altitude, slope aspect and species compositions were selected for the study. Physical properties of soil i.e., soil colour, soil texture (per cent of sand, silt and clay), moisture content, water holding capacity, porosity, bulk density (gm/$cm^3$) and void ratio were analyzed for three different depths viz., (i) 'upper' (0-10 cm), (ii) 'middle' (11-30 cm) and (iii) 'lower' (31-60 cm) in all the selected forest types. Phytosociological and diversity parameters viz. total basal cover ($Gha^{-1}$), stem density ($Nha^{-1}$), tree species richness, Simpson concentration of dominance and Shannon-Wiener diversity index were also calculated for each forest type. This study also provides the comparisons between the results of physical analysis of the present study with numerous other previous studies in the temperate Himalayan region of the Uttarakhand.

We have analyzed the external morphology and the environment of the foraging site of Vespertilio sinensis. The external morphology was analyzed by twelve parameters and the environment characteristics of the foraging site was analyzed using GIS 10.1 program. The wing membrane was inserted into the ankle of the hind foot and the wing ratio was 1.42, the middle type between broad-short wing type and long-narrow wing type. The fur color was blackish brown but the guard hair color was whitish. The shape of the ear was a rounded triangle and tragus was a fan shape. This study showed that V. sinensis preferred the deciduous forest of the upper forest zone, where human interference was less. We believed that abundance of insects, depending on water system, was closely related to the use of the foraging site. This result showed that the environment characteristics was very similar to the nature preservation zone including Baekyang valley and Keumsun valley in Naejangsan National Park.
