The twenty eight taxa of rare and endangered plant species of Oesorak were investigated in the field, and the results were compiled according to the literature by Lee et al.(1996). Most of the populations of the investigated plants are located in the vicinity from the mountain trails which is the destruction pressures high. Also these plants are envisaged from the possible collections for both edible and medicinal purposes by local peoples, so the conservation strategies at the levels of habitat and species must be prepared. Taxuscaespitosa of Taxaceae has very few individuals and the status of the habitats envisaged serious problems from tramplings.

The flora of Oesorak in the Soraksan National Park including Chombongsan(Mountain) and Kwanmobong(Peak) were surveyed from February to August, 1996. These areas have very rich and diverse flora;620 taxa with 89 families, 321 genera, 526 species, 2 subspecies, 89 varieties and 3 forms in the Oesorak, 404 taxa with 251 genera, 350 species, 1 subspecies, 51 varieties and 2 forms in the Chombongsan(Mountain), 286 taxa with 206 genera, 233 species, 1 subspecies, 50 varieties and 2 forms in Kwanmobong(peak). The Oesorak had very distinct floristic characteristics such as the wild habitats of Asarum maculatum(Aristolochiaceae) and Ilex macropoda(Aquifoliaceae). In the phyorgeographical point of view, the six species such as Sapium japonicum (Euphorbiaceae), Euphorbia joldini(Euphorbiaceae), Ilex macropoda (Aquifoliaceae), Styrax japonica (Styracaceae), Carex sideros ticta (Cyperaceae) and Asarum maculatum (Aristolochiaceae) were naturalized into this region, while the 17 taxa such as Abies neprolepis(Pinaceae), Pinus pumila(Pinaceae), Thuja koraiensis(Cupressaceae), Allium senescens(Liliaceae), Lilium distichum(Liliaceae), Saxifraga punctata(Saxfragaceae), Rosa marretii(Rosaceae), Bupleurum euphorbioides(Umbelliferae), Androsace cortusaefolia (Primulaceae), Peducularis mandshurica(Scrophulariaceae) and Leontopodium coreanum (Compositae) were distrivuted to this region. The colonizing weedy species such as Ixris repens (Compositae) were distributed to this region. The colonizing weedy species losa(Labiatae) and Rosa rugosa(Rosaceae) were naturalized into ca. 900m at sea level mainly due to the sand soil from the seashore. Mountain roadbed is susceptible than other areas to the slippery road problems, due largely to snow and rain, particularly during winter. Sand soils from seashore are utilized to minimize this slip in traffic operation.

The annual increasing rate of visitors was 3 percent in Soraksan National Park form 1990 to 1997. Secenty nine percent of total visitors in Soraksan National Park has visited Oysorak district due to convenient access and facilities. Approximately, 6~17 percent of visitors passing through Sorakdong ticket office at Oysorak district has climbed up Taech'ongbong(peak), the others have visited Ulsanbawi, Pisondae and Madungnyong close at hand. Climbers from Osekyaksu to Taech'ongbong(peak)were more in autumn than in summer. Visiting pattern in Soraksan National Park showed differences by districts, seasons and days of the week.

설악산국립공원은 1965년에 천연보호구역, 1970년에 국립공원 제 5호, 1982년 유네스코에 의해 생물권보존지역으로 지정된 지역이다. 우리 나라 국립공원에서는 물론 다른 자연보존지역에서도 찾아볼 수 없는 중요성이 강조된 지역이나 연간 400만명의 이용객이 집중되기도 하는 지역이다. 우리 나라 국립공원은 본래 관광개발을 위해 지정된 동기를 갖고 있어 자연생태계 및 자연경관도 중요하지만 현실적으로는 합리적인 이용도 중요하다. 그러나 지금까지 국립공원은 자연보존에 대한 관리는 도외시 한 채 이용객 집중에 의해 발생되는 도로, 시설물, 건축물, 각종 오염에 대한 대책마련도 제대로 하지 못하여 국립공원하면 국민은 '등산이나 하고 값싼 음식점과 여인숙 수준의 숙박시설이 있는 관광지'정도로 인식하고 있다. 지난 30년간 압축고도성장을 해 온 우리 나라는 국토의 자연환경이 수없이 훼손되고 또한 옥외 레크레이션활동의 증가로 환경오염이 계속 증가되었다. 설악산국립공원도 예외는 아니어서 저앗ㅇ부와 등산로 주변생태계, 계곡생태계 등이 오염되어 식물, 포유동물, 물고기, 곤충 등에 영향이 나타나고 있지만 대피소, 휴게소, 숙박시설을 중심으로 한 오염행위는 계속 늘어만 가고 있다. 이제 설악산국립공원은 거의 위기상황에 도달된 느낌이다. 이런 시기에 환경생태학회 국립공원분과위원회 회원들은 `96년 외설악 지역, `97년 내설악지역을 2년 동안 각 분야에 걸쳐 조사를 수행하였다. 지난 12년간 외부의 지원도 없이 연구비를 자체 조달하여 힘들게 국립공원 연구를 진행하여 온 일환으로 설악산국립공원 조사를 2년 동안 수행한 것이다. 이번 조사는 `96년 가을 북한공비침투로 많은 지역에 대한 출입이 통제되어 외설악연구의 일부가 누락되었음을 첨언한다. 본 글에서는 2년 동안 본 회원들이 조사한 내용에 의해 설악산 국립공원의 현황을 분석하고 관리개선 방향을 제시하였다.

Herpetofauna in Soraksan National Park was carried out both Apr. 27, Apr. 28, 1996 and Aug. 19, Aug. 20, 1996. 6 stecies of 4 Families in Amphibian and 2 species of 2 Families in Reptilian were observed in this survey. It was observed relatively poor biota to other National Park that caused to excessive visitor and impacts by divelopments. Onychodactylus fischeri which was revealed Specific Endangered Animal assigned by Minister of Environmemt distributed abundantly along the Chohangnyong. So Chohangnyong should be conserved by prolonging the Year of Natural Rest.

Six trails of Naesorak(west Sorak) district of Soraksan National Park were selected to investigate the use impacts on environmental edterioration of trail according to the different amount of use. The entire width, and slope of trail as the trail condition surveyed at the total of 132 points were significantly varied with the amount of use. Major deterioration types of trail were rock-exposure, root-exposure, deepening and divergence in order of frequency. Deteriorated points were significantly different in trail conditions from non-deteriorated points, and these latter generally appeared at the lowed altituede than the former on each trail. Naesorak district still seemed to have poorer use-impacts than Oesarak(east sorak) district. The dominant species in upper layer of trail edge vegetation differed from trail to trail, but in shrub layer Lespedeza maximowiczii, lindera obutsiloba for valley trail and Rhododendron schlipenbavhii for slope trail. The species diversity and coverage of shrub layer in trail edge were the highest on the Ose'am trail and each trail was dissimilar in species composition of shrub layer of edge vegetation.

The population of Asarum maculatum of Aristolochiaceae was recorded for the first time in this region. In the view of phytogeograghy, the 18 taxa such as Pinus pumila of Pinaceae, Leontopodium coreanum of Compositae, Leontice micoryncha of Berberidaceae and Rhododendron aureum of Ericaceae, etc. were recorded as northern elements, while the taxa such as Asarum maculatum of Aristolochiaceae, Styrax japonica of Styracaceae and Carex siderosticta of Cyperaceae as southern elements.
