Amphibian and Reptilian fauna in Chuwangsan National Park was carried out both Apr. 28, 1994 - Apr. 30, 1994 and Aug. 4, 1994-Aug. 5, 1994. 7 species in 5 Families in Amphibia and 7 species in 3 Families in Reptilia were observed in this survey. Rana dyhowskii in Amphibia and Rhabdophis tigrinus tigrinus in Reptilia were revealed dominant species in Chuwangsan National Park. The results in this survey would be use to baseline data significantly after the project of construction works in Chuwangsan National Park.

Visitors to Chuwangsan National Park were survayed from August 3 to 5 n 1994. During this time, 346 visitors were contacted. Of those individuals, 65% were males. 63% of respondents reported that they had gone as far as college. 48% were 20 years of age. 97% of the survey respondents had experience to visit other national parks. The largest percentage of respondents were reported that they visited Chuwangsan Nat'1 Park for enjoying natural landscape. In group type, 50% were traveling with their family and 36% with their friends. In activity characteristics, 51% were day-time visitors, and 18% mentioned carrying in their on food. Generally most respondents were very interested in the environmental problem in national parks. The majority of visitors perceived that the environment of Chuwangsan Nat'1 Park were good enough. In six types of normative violations, the major reasons of littering were unintentional violation and releaser-cue violation. Most respondents were not likely to intervene to stop other visitors' depreciative behavior (Bystander intervention behavior). In two dilemmas, the more likely the intention to obey a regulation the less likely the intention to disobey a regulation, and vice-versa.

The flora of the Chuwangsan National Park was surveyed. The field works was done for three times from February to October, 1994. The total number of vascular plants in this area were surveyed as 433 taxa ; 94 families, 260 genera, 365 species, 60 varieties, 2 subspecies, 5 formas, and 1 cultivars. The twenty seven taxa which were artificially planted could be found at the temple and abandoned cultivated areas. The population of Jeffersonia dubia Benth, one of the rare and endangered plants in Korea, were surveyed and mapped for an ecological monitorings in the future. Since this population is restrictly located in the vicinity of the mountain trails, the protection measures should be urgently needed in the future.

To investigate the structure and the conservation strategy of natural forest at Nature Conservation Area in Chuwangsan, 21 plots(20$\times$20m) set up with random sampling method. Two groups were classified by cluster analysis. High positive correlations was proved between Carpinus laxiflora and Fraxinus rynchophylla, Quercus serrata and Quercus variabilis, Lindera obtusiloba and Stephanandra incisa and High negative correlations was proved between Acer mono and Fraxinus sieboldana, Acer pseudo-sieboldianum and Quercus variabilis. Species diversity(H') of investigated area was calculated 1.1306~1.2688.

To investigate the structure and the conservation strategy of natural forest at Wangkoam and Kumunkwangi Area(400-700m) in Chuwangsan, 23 plots(20$\times$20m) set up with random sampling method. Two groups were classified by cluster analysis. High positive correlations was proved between Carpinus laxiflora and Tilia amurensis, Acer mono and Deutzia parviflora, Lespedeza maximowiczii and Sorbus alnifolia, and High negative correlations was proved between Prunus padus and Sorbus alnifolia, Acer mono and Fraxinus sieboldiana, Deutzia parviflora and Quercus variabilis. Species diversity(H') of investigated area was calculated 1.2167-1.3945.

The freshwater fish fauna of the Chuwangsan National Park as censused during June 1994 to December 1994 at 11 sampling sites to establish baseline data included 7 Korean endemic species and subspecies (Squalidus gracilis majimae, Squalidus multimaculatus, Cobitis longicorpus, Niwaella multifacisciata, Silurus microdorsalis, Liobagrus mediadiposalis and Odontobutks platycephala) belonging to 17 species in 6 families were collected in this region. Carassius auratus, Moroco oxycephalus, Zacco platypus, Wacco temmincdii, Misgurnus anguillicaudatus, Liobagrus mediadiposalis and Odontobutis platycephala were distributed at all of the regions on this sensus. Dominant species of thes region sere Moroco ozycephalus, Zacco temminckii and Odontobutis platyxephala.

Autumn visitors to Chuwangsan National Park was more than summer's. About 89% of total visitors used main trail but approximately 35% visited to the Third Falls. The entire width, bare width, maximum depth and slope of trail as the trail condition surveyed at the total of 103 points were significantly greater on the more heavily-used trail. Trail conditons of rock-exposed, root-exposed, deepening points as the deterioration types of trail were significantly different from those of non-deteriorated points. According to the topographic position of trail, severe difference of dominant trees in the edge vegetation was found and Lespedeza maximowiczii, Rhododendron yedoense and Fraxinus sieboldana were dominant in shrub layer of trail edge vegetation. The crown coverage, number of species and individuals of shrub layer in edge vegetation were generally higher than those in the other national parks with more heavily-used trail.

To investigate the plant community structure in Pinus densiflora forest of Chuwangsan National Park, twenty five plots were set up and surveryed. The classification by TWINSPAN and DCA ordination techniques were applied to the study area. The plant community were divided into five groups in twenty five plots by DCA and the dividing groups were Pinus densiflora-Quercus variabilis community(I), P. densiflora-Q. serrata community(II), P. densiflora-Fraxinus sieboldiana community(III), P. densiflora-F. sieboldiana-Q. spp. community(IV) and P. densiflora-mixed deciduous forest community(V). The successional trends of tree species by DCA ordination techniques and DBH class distribution analysis seems to be from P. densiflora through Q. mongolica, Q. serrata to Carpinus laxiflora in the canopy layer group. And in the subtree and shrub layer, it was expected that Lespedeza maximowiczii, L. cytobotrya, Rhododendron mucronulatumlongrightarrowStyrax obassia, Stephandra insisa, Zanthoxylum schinifolimlongrightarrowAcer pseudo-sieboldianum, Lindera obtusiloba. There was no difference between the stand scores of DCA and soil pH, and soil moisture.

To investigate the forest structure of Chuwang valley of Chuwangsan National Park, thirty plots were set up and surveyed. Importance values, DBH class distribution, species diversity indices, DCA Ordination, CCA ordiantion and TWINSPAN classification were used for vegetational structure analysis. Pinus densiflora Quercus serata, Q. mongolica, Q. variabilis were appeared to be dominant species in thirty plots. According to the analysis of classification by TWINSPAN, the thirty plots divided four groups. Groups were Q. mongolica-P. densiflora-Carpinus laxiflora community(I), P. densiflora-Q. variabilis community(II), Q. serrata-Q. variabilis community(III), broad-leaved mixed community(IV) Species diversity(H') of investigated area was calculated 1.17~l.32. The successional trend was seemed to be from P. densiflora to Q. spp. in the canopy layer.

This study was conducted to investigate bird community and to suggest a proper way how to manage and protect wildbirds in Chuwangsan National Park. The survey was carried out over two survey sections by the line transect method in spring, summer and autumn in 1994. Total number of observed birds were 42 species(33 species in spring, 32 species in summer, and 26 species in autumn), and the result was the same with the typical pattern of temperate bird communities. Total number of natural monument and rare birds were 7 species, which included Golden Eagle(Aquila chrysaetos), Chinese Sparrow Hawk(Accipter soloensis), Eagle Owl(Bubo bubo), etc. In breeding season, species richness was high in canopy nesting guild, and density(ea/ha) was high in hole nesting guild. Canopy foraging guild was dominated in spring and summer, ratio of bush(or ground) foraging guild was increased in autumn. Since the habitats of observed natural monuments and rare species were roughly overlapped with the nature preservation area, it is necessary to preserve the area completely and to investigate and protect these species continuously. For the protection of the bush(or ground) foraging guild, it needs to plant bushes around trails and to control users. Food plants, artificial food planting of bushs, and artificial nest are needed for the habituation of wildbirds, and as the damage of wild cats is increasing lately, it needs to control these cats.
