Gap formation and susceptible Abies trees to windthrow in the forests of Odaesan National Park

정연숙,Mina Jeon,Kyungeun Lee 한국생태학회 2015 Journal of Ecology and Environment Vol.38 No.2

Extremely strong winds and heavy rainfall caused canopy gaps in a mixed Abies holophylla broadleaf forest and a Quercus mongolica-dominated forest in Odaesan National Park, Korea in October 2006. The impact of the combination of strong winds and torrential rain on the development of forest gaps and canopy structures were investigated. The mean size of newly created gaps were 205 m2 in the mixed forest and 86 m2 in the Quercus forest, and were created by 2.8 and 1.4 gap-maker trees, respectively. Among the 73 trees lost in the mixed forest, 59% succumbed because of direct wind damage while 41% were struck by neighboring trees that fell into them. Most of these trees downed by wind were uprooted (74%), while the trees downed by neighboring tree falls snapped (78%). 21 trees in the Quercus forest died from direct wind dam¬age, and 57% of them were uprooted. Although the relative density of Abies nephrolepis and A. holophylla represented only 0.2% and 6.4%, respectively, of all species in the intact mixed forest, they accounted for 27% and 15%, respectively, of all trees affected by wind on that site. In fact, 85% of the total A. nephrolepis and 91% of the total A. holophylla in the mixed forest fell directly due to strong wind. By contrast, only one Abies species, A. nephrolepis, was found in the Quercus-dominated forest, and it accounted for 7.3% of the species composition. These findings suggest that A. nephrolepis and A. holophylla are particularly susceptible to high winds because of their great heights and shallow root systems.

To investigate the status of current vegetation in the Paekdoo Great Mountain Chain, 51 maps of actual vegetation and 51 maps of the degree of green naturality were analyzed from Hyangno-Bong to Chirisan, which includes the watershed of the chain. Forest area covered average 81.7% in the chain; deciduous forest 34.9%, coniferous forest 37.4%, plantation 8.9% and pasture 0.5%. If we considered the potential vegetation of cool temperate deciduous forest, coniferous forest, represented by Pinus densiflora, still remained in quite a wide area. Oak group, mainly Ouercus mongolica occupied relatively conserved regions including Several national Parks. Larx leptoloepos pinus rigida and Pinus koraiensis were planted mostly in the south of the southern Kangwon-Do, except Chili-san area. As we calculated the area over 8th degree of green naturality, as indicators for the successional status and degree of naturality, it was average 47.9% of forest area. Especialiy, it was over 80% in most regions of northern Kangwon-Do, but that of the area from Sokrisan to just before Chirisan area was only 19%, which means that the vegetation in the southern regions of the Paekdoo Great Mountain Chain wore poorly de-veloped by plantations and disturbances such as logging, clearing and fire.Overall, the vegetation of the Paekdoo Great Mountain Chain is fairly in a good condition in terms of forest area and degree of naturailty, compared to the other areas. Moreover, several conservation regions have been designated by several authorities including 7 representative national parks and 2 natural ecosystem conservation zones. However, its condition varies regions to regions, thus the development of special policy for the south regions of Sokrisan is required: such as the protection of forcst area and the prohibition of anymore plantation in the area. For the better accomplishment, the Paekdoo Great Mountain Chain itself should be designated as a core preserved for green network, first.

지리적 위치, 기후, 지형 등의 조건 때문에 우리나라는 이탄습원이 매우 희귀하다. 대암산의 큰용늪은 보전상태가 양호하고 특징적인 식물상을 가져 우리나라 대표적 산성 이탑습원으로써 특히 중요하다. 그동안 식물상이 지속적으로 보고되어왔으나 연구결과 간에 큰 차이를 보였다. 따라서 큰용늪의 초본 식물상을 연구하고 그간 발표된 식물상과 비교 검토하였다. 본 연구결과 큰용늪의 초본식물은 총 130분류군(관속식물123 분류군, 선태식물문 7분류군)이 푼포하는 것으로 확인이 되었다. 단자엽식물이 37분류군(관속식물의 30%, 사초과 12분류군, 벼과 7분류군)이나 분포하여 산성이탑습원의 종조성 특징이 확인되었고, 우리나라 북부와 강원도 이북에 분포하는 종이 23분류군(관속식물의 19%)으로써 식물구계학적 중요성이 밝혀졌다. 이 결과에 기초하여 뚝사초(Carex thunbergii var. appendiculata), 진퍼리새(Molinia japonica), 대암사초(Carex chordorrhiza), 대택사초(Carex limosa)등 산성이탄습원의 지표종, 우점종 및 식물 구계학적 특징종 등 18 분류군을 기존 문헌의 식물상과 비교하고 논의하였다. 식물상은 생태계의 가장 기초적인 정보일 뿐만 아니라 산성이탄습원의 분류에서도 중요한 기준이다. 연구자간의 상호 검토를 통해서 정확한 식물상 정보가 제공되어야 할 것이다. Due to geography, climate and topography, peatlands are very rare in Korea. Especially Keunyongneup is a well preserved raised bog with the unique flora. The floristic compositions have been reported, but showed large difference among repotrs. Therefore, this aimed to investigate the herbaceous flora of Keunyongneup and to review the preexisted reports. Total 130 taxa identified from the Tracheophyta and Bryophyta. Among these, 37 taxa (30% of total Tracheophyta) belong to Monocotyledon and 28 taxa (19% of total Tracheophyta) is known to distribute in the Northern part of Korea. The identification and the presence of 18taxa, which are dominant species, characteristic species geographically and/or indicator spedies, were reviewed with other reports. As an example, the representative bog species, carex thunber gii var. appendiculata, has been reported as C. dispalata in many reports. It is because the field surveys might have conducted in season without inflorescence. The floristic composition with correct information should be provided to understand the rnique raised bog, Keunyongneup.

정연숙,Woo Tchul Lee,조강현,Kwang Yeong Joo,민병미,현진오,이규송,Kyungeun Lee,Anna Seo 한국생태학회 2015 Journal of Ecology and Environment Vol.38 No.4

We report the status of wetland vascular plant species in Korea including the whole peninsula and its adjacent islands. This analysis was based on database from our previous categorized list. In all, 4,050 taxa have been reported, including 3,769 native and 281 naturalized. Of these, 479 taxa (12%) are considered as wetland vascular indicator species: 240 obligate wetland plants (OBW) and 239 facultative upland plants (FACW). Approximately 31% of those 479 taxa, i.e., 149 taxa, are labelled as aquatic macrophytes. Wetland plants, mostly herbaceous but some woody, inhabit aquatic bodies and wet meadows. Except for two OBW and six FACW taxa, the rest of the plants are summer-green only. The information provided here is valuable for making assessments of wetland ecosystem health, as well as for developing management plans to preserve and restore wetlands and their resident plant species while also creating artificial wetland environments.

현대무용으로 알려져 왔던 예술 형태는 20세기의 초반기에 연극성을 띈 무용의 유형적인 형태에 이의를 신립함으로써 나타났다. 즉 19세기 말부터 20세기 초반에 걸쳐 예술의 각 장르에서 각개의 예술적 독자성에 눈을 뜨기 시작하면서 혁신을 이룬 것이며 무용세계에서의 혁신은 현대무용의 발생으로 볼 수 있다.

Radicoid structure of herbaceous communities in Mt. Kumbyung, Chunchon, Kangwon-Do was clarified emphasizing on the dominance of clonal plants in relation to vegetation development. In the total vegetation, 46% species identified were rhizomatous, 26% were species with tap roots, and 13% were stoloniferous species. Thus, all clonal species, including plants with bulb, corm and tuber, covered 62.8% of the total species. In the understory of Quercus, Pinus and Larix forests,68.2% were clonal, which means 5% more compare to total vegetaion. Dominance of clonal plants became more conspicuous as their importance value was calculated. That is, they covered average 86% for the following three communities: 85% in Quercus, 95% in Pinus and 76% in Larix Especially, the rhizomatous plants were remarkable. Overall, clonal species dominated over the other radicoid types in terms of not only the number of species, but also the importance value. Dominance of these species was more peculiar in understory of forests, indicating the occupancy of clonal plants was related to the vegetation development.

To elucidate the effects of a hydroelectric dam construction on annual ring growth of Pinus densiflora, the annual ring widths of 68 trees collected from 7 sites were closely examined, The result was analyzed to ask three special questions; first, whether there are real effects of dam construction on the radial growth; second, would the magnitude of the effect be different due to two periods of underconstruction and post-construction; the last, would it be different among age classes. Annual ring growth has been significantly enhanced by the dam construction. Specially, its effect was marked after the construction was finished and the reservoir was filled up with water. There was, however, no remarkable evidence that pine growth would be reduced while the dam was under construction, even though there was a minor decreasing trend. The magnitude of the effect was different among age groups, That is, the changed condition alter the construction enhanced relatively the growth of aged trees more. According to other meterological research since the dam was constructed, the reasons of enhancing pine growth assumed to be the increase of daily temperature, the decrease of daily temperature difference and the increase of rainy days
