Roads are an indicator of anthropogenic activity causing ecosystem disturbances and often lead to habitat fragmentation, habitat loss, and habitat isolation. The Hallasan National Park(153.4$km^2$) on Jeju Island being distinguished for its unique geology, topography, and biota has also been designated as a core area of UNESCO Man and the Biosphere(MAB) Reserve. Although the high conservation value of this park has contributed to a rapid growth of tourists and road construction, landscape changes due to roads have not been examined yet. We used GIS systems to examine the fragmentation pattern caused by roads, in relation to its zonation, elevation, and vegetation. When a buffer was applied to roads(112m width for paved roads and 60m width for both legal and illegal trails), the park consisted of 100 fragments. The ten fragments generated after applying buffer to only paved roads and legal trails ranged from $0.002km^2$ to $38.2km^2$ with a mean of $14.2km^2$, and about 7% of both nature conservation zone and nature environment zone of the park were edge. Fragments in both east and west ends of the park and around the summit exhibited relatively high shape indices with means of 5.19(for 100 fragments) and 7.22(for 10 fragments). All five legal trails are connected to the pit crater of the mountain and vegetation changed from broadleaf forests and conifer forests to grasslands with elevation, consequently resulting in dramatic fragment size reduction in grasslands at high elevation, in particular above 1,400m, where endemic and alpine plants are abundant. These results show that in Hallasan National Park the risks of habitat deterioration and habitat loss due to fragmentation may be more severe in the nature conservation zone dominated by Baengnokdam than in the nature environment zone. Therefore, current road networks of the park appear to fall short of the goal of the national park for ecosystem conservation and protection. Considering that the entire Hallasan National Park also serves as a MAB core area, conservation efforts should focus, first of all, on park rezoning and road management to mitigate habitat fragmentation.

This study was carried out to propose the baseline data for in situ conservation by analyzing environmental and growth characteristics in Pedicularis hallaisanenesis habitats. P. hallaisanensis habitats, according to investigations, were located on the slope of southwest at an elevation of 1,400 m in Mt. Gayasan and on the slope of southeast at an elevation of 1,500 m in Mt. Hallasan. Pedicularishallaisanensis habitats. Also, habitats were found at the grassland with no upper vegetation. In the study sites, soil pH and soil organic matter were 4.9-6.5 and 4.4-8.1%, respectively. A total of 55 vascular plants taxa were identified in ten quadrats in two habitats, of which 25 were inhabited in Mt. Gayasan and 37 in Mt. Hallasan. Current status of P. hallaisanensis habitats were very vulnerable with the pressure of the vegetation constantly threatening the species' survival. Thus, concrete conservation plans including diverse factors as light intensity, temperature and genetic analysis to protect natural habitats should be set up as soon as possible.

This paper is concerned with the problem of international approval of national parks in Korea. Much of the solution of this problem is to be found in planning and law. Therefore the provisions for planning in the Korean. Natural Park Law and 20 national park plans were analyzed in comparison with International criterion. Then an gradual changing model of zoning plan were proposed in order to improve the zoning plan of national parks in Korea and applied to Hallasan National Park. These model can be applied to change the zoning plans of national parks in Korea for international approval.

This study was carried out to investigate the herpeto-fauna at Hallasan National Park. We conducted a survey at 1100 Resting places, Eoseungsaengak, Donnaeko, Eorimok, Yeongsil, Gwaneumsa and Seongpanak from April, 2006 to January, 2007. A series of four families and 5 species of amphibians and 4 families and 8 species of reptiles were observed. Amphiesma vibakari ruthveni, Takydromus wolteri, Scincella vandenburghi, Coluber spinalis and Hynobius quelpartensis which are rarely appearing inland but they were frequently observed by this survey. Also, we observed Sibynophis chinensis that only inhabits Jeju island with in Korea. Jeju island has both southern and northern boundary lines for amphibians and reptiles. Amphibians and reptiles in Jeju island have a different from those inland and valuable information for biogeograpy due to dissimilar climate and isolation from continental for a long time. It is not certain whether some amphibians and reptiles, Bufo gargarizans, Rana rugosa, R. plancyi, Elaphe rufodorsata and Takydromus amurensis, inhabit Jeju island, as recorded in previous literatures, so the research on current status of them has to be carried out immediately.

Hallasan National Park is facing dramatic increase of visitors since no entrance fee charge effected in January of 2007 and it has created a concern about appropriate use levels. The overall objective of this study is development of the carrying capacity indicators management program using indicator and standard based on visitor experience and resource protection (VERP) model. The result of delphi survey identified eight potential indicators of resource and experiential conditions, including quality of valley water, visitor counts, trail impacts, crowding etc. Also, Data were also gathered to help provide an empirical foundation for setting standards for these indicator variables. The carrying capacity indicators management program based on VERP model estimates sustainability of national park and analyze scientifically change about resources and visitor's behavior. Also, it systematically manage and use united data, it supports operation accomplishment respected rational decision.

Hiking trails in Mt Jiri, and Mt Halla, National Park have been examined in terms of their degrading factors. The trails are deteriorated by natural erosion processes as well as human trampling. Trail deterioration is classified into tread lowering, sidewall retreat, path widening and divergence based upon a place where erosional processes occur. Tread lowering and sidewall retreat is generally produced by natural erosion factors, whereas path widening and divergence is generated by human trampling. Rainwash is the most contributing process to tread lowering. By contrast, several processes such as rainwash, needle ice action, deflation, tree falling and animal activity play a major role in sidewall retreat according to physical conditions of a hiking trail. Path widening and divergence could be classified by a factor producing human trampling. There are lots of cases related to rainwash such as the tree root, gravel, and bedrock, exposed by a surface flow lowering a tread and the riser produced by tread scouring. A puddle of rainwater on a flat tread and a fallen tree of Abies koreana in a forest region are also major factors to cause path widening and divergence. A paved tread with stones encourages a hiker to walk out of a trail. Taking a shortcut also results in path widening and divergence without a factor giving a hiker inconvenience on a trail.
