  • To identify the characteristics of the dropping habits and to provide improved methods for sign survey of Siberian flying squirrels Pteromys volans, an investigation was carried out in Jirisan National Park from April 2012 to May 2013. The latrines of study area were checked once a month and the characteristics of dropping behavior were camera trapped. The feces of Siberian flying squirrel were found on the point which tree forked, mostly from November to May. The squirrel actively presents in forked tree mainly on the September to April. The Siberian flying squirrel is found to be a typical nocturnal animal as it actively move between 6p.m. to 7a.m.. The study found that squirrel does feeding and dropping in the winter time on forked tree. On the point which tree forked could be a good place for the squirrel to hide from their predator when there is no leaf on the tree. Conducting the sign survey is advisable from November to May, as well as with the careful approach to the animals. As Siberian flying squirrel is an endangered species, adjusting the survey period is mandatory, especially when doing environmental impact assessment and a research on its dwelling areas.

  • This study was conducted to investigate the vascular plants which can be an indicator of environmental change in Seseok of Jirisan National Park. The purpose of this study was to find out the basic information for the subalpine species. This study showed that the area had a total 295 taxa including 63 families, 177 genus, 252 species, 2 subspecies, 36 variants 5 forms and Pte-Q was 1.7. Among them, Korea endemic plants were 15 taxa such as Abies koreana. Rare plants were 14 taxa such as Viola diamantiaca. Naturalized plants consisted of 5 taxa such as Rumex crispus. The floristic regional indicator plants found in surveyed area were 72 taxa comprising 3 taxa of grade V, 7 taxa of grade IV and 24 taxa of grade III. In summary, The subalpine plants of the survey region consisted of 37 taxa including Abies koreana and Gymnadenia cucullata. As rare plants distributed in subalpine zone respond sensitively to climate change, accuracy distribution range, environmental characteristics of habitat and population dynamics of rare plants should be evaluated quantitatively.

  • Although landslides were frequently occurred under Tripterygium regelii and Rubus sp. vegetations, the damage of landslide was not observed in sasa (Sasa borealis) stands. These phenomena may be affected by forest vegetation types. This result suggested that the landslide occurred in Jirisan (Mt.) National Park may be closely related to water retention capacity at Sasa borealis stands. This study compared and analyzed the water retention capacity of each soil horizon of sasa, larch (Larix leptolepis) and mongolian oak (Quercus mongorica) stands. Soil bulk density in A horizon was lower in sasa (0.776g/$cm^3$) than in mongolian oak (0.828g/$cm^3$) and in larch stands (1.282g/$cm^3$). Water permeability in A horizon was 0.02055cm/sec for sasa, 0.00575cm/sec for mongolian oak, and 0.0007cm/sec for larch stands, respectively. The water permeability of sasa stand was about 3.6 times and about 29 times higher than in mongolian oak and in larch stands, respectively. This result indicates that water infiltration of soil surface during a rain event is more rapid in sasa than in other two stands. Soil organic matter content in B horizon was lower in larch (0.7%) than in mongolian oak (6.5%) and in Sasa (3.3%) stands. The solid ratio in A horizon was highest in larch among three stands, but that of mongolian oak and larch stands showed a similar rate. Pore space rates was 70.7% for A horizon and 70.6% for B horizon of sasa, 68.9% for A horizon and 70.6% for B horizon of sasa, 68.9% for A horizon and 70.6% for B horizon of mongolian oak forests and 51.7% for A horizon and 49.2% for B horizon of larch forests, respectively. According to pore space rates, the water retention capacity may be poor in larch stand compared with other two stands. Soil strength in sasa and mongolian stands was over 25kgf/$cm^2$ from 40cm depth, while the strength was over 25kgf/$cm^2$ from 25cm depth in larch stand. The result indicates that tree growth and water permeability in larch stand could be limited due to high soil strength. Larch stand was poor for soil pore space development to be offered to the water retention capacity, but water retention capacity of A horizon soil in sasa stand was high than that of other two stands. Therefore, establishment of sasa stand under larch stand could help to prevent landslides.

  • To investigate the restoration procedure on soil physical properties at the surface of visiting road affected by rest-year system. This study was carried out at visiting roads of stream of Chilsun in Jirisan. Mean soil strength in 20cm of soil depth was lower in the Rest-Year System areas (1.5-1.9 times in Site 2, 1.1-7.5 times in Site 3) than in the control (Site 1). Soil strength was recovered by the Rest-Year System in the national park. Mesopore rate (pF 2.7) in 0-15 cm of soil depth was higher in the Rest-Year System areas (1.2 times) than in the control. This indicates that mesopore rate is rapidly restoring in the Rest-Year System areas. Pore space rate in 0-7.5 cm of soil depth was higher in the Rest-Year System areas (23.2% in Site 2, 23.6% in Site 3) than in the control (22.4% in Site 1). Pore space rate in 7.5-15 cm of soil depth was also higher in the Rest-Year System areas (22.9% in Site 2 and Site 3) than in the control (18.9% in Site 1). Soil pore space was remediable by the Rest-Year System. Bulk density in 0-7.5 cm of soil depth was lower in the Rest-Year System areas (1.674g/$cm^3$ in Site 2, 1.668g/$cm^3$ in Site 3) than in the control (1.723g/$cm^3$ in Site 1). Bulk density in 7.5-15 cm of soil depth was lower in the Rest-Year System areas (1.785g/$cm^3$ in Site 2 and 1.721g/$cm^3$ in Site 3) than in the control (1.721g/$cm^3$ in Site 1). Soil bulk density was decreased in the Rest-Year System areas of the national park. Amount of soil erosion was lower in the Rest-Year System areas ($0.017m^3$/km/yr in site 2, $0.023m^3$/km/yr in site 3) than in the control ($0.054m^3$/km/yr in site 1).

  • 지리산국립공원 피아골과 대성골 지역의 산림군집구조의 동태를 장기간 모니터링하기 위하여 2001년에 고정조사구를 설치하여 2001년과 2006년에 식생조사를 한 결과는 다음과 같다. 피아골, 대성골 지역 산림의 우점종은 각각 서어나무와 신갈나무였으며, 피아골 지역의 산림이 대성골 지역보다 종다양도 지수가 더 높았다. 조사지역 주요수종의 직경급분포로 보아 안정된 식물군집 구조를 이루고 있으며, 곡간부에 위치한 피아골의 산림과 소능선 사면부에 위치한 대성골의 산림간 종구성은 매우 이질적이었다. 피아골지역 산림의 생장량은 지난 5년간 약 $6.4m^2/ha$ 감소하였으나 대성골지역은 약 $8.27m^2/ha$ 증가하였으며, 이는 노거수들의 고사에 따른 영향으로 보인다.

  • 본 연구는 고도에 따른 곤줄박이(Parus varius)의 산란생태의 차이를 파악하기 위해 지리산 지역에서 수행하였다. 고도가 다른 세 지역(약 300, 900, 1500m)에 인공새집을 설치한 후 알의 크기, 한배산란수, 첫 산란일을 조사하였다. 조사 결과 알의 크기는 고도에 따른 차이를 보이지 않았지만, 한배산란수는 고도가 높아짐에 따라 작게 나타났다. 또한 첫 산란일도 차이를 보이는 것으로 나타났다. 본 연구에서 나타난 한배산란수의 차이는 '개체 적응 가설'에 의한 결과로 판단하고 있다. 그리고 첫 산란일에 차이는 잎의 개엽 시기, 곤충의 분포형태와 밀접한 관련이 있는 것으로 판단된다.
