Having the Seorak mountain National Park as an object of study, this research grasps the problems of the present environmental observatories through the awareness investigations of visitors towards the function of environmental observatories made by the evironmental education. In order to achieve this, a questionaire has been conducted for 26 days, starting from the 25th October 2002, directed towards 100 visitors to the Seorak mountain National Park about the maps and degree of satisfaction of the usage ofthe environment observatory and explanation program. The results of the analysis show that general satisfaction on the environmental observatories are valued very negatively. This informs us that the present environmental observatories under the environment education are not fullfilling entirely their functions. Supporting itself upon the basis of the visitors' questionaire, this research has attempted the resolution of the present problems having as an object of study the scenery and cultural resources present in the Seorak mountain National Park, and proposing an entertaining environmental education of the environment observatory's constitution.

One new species of cellular slime molds, Dictyostelium caudabasis sp. nov. Shim et chang, is isolated from soils in the Quercus mongolica forest of Seorak monutain, South Korea. D. caudabasis is charaterized by small sorophores, scarecely phototrophic, irregularly or sparsely branches, capitate-simple or capitate-compound and sometimes obtuse-simple tips, and conical and sometimes clavate bases. Spore are elliptical, $6.52~4.82{\times}3.40~2.83{\mu}m(avg.\;5.72{times}3.17{\mu}m$), L/W index 1.70-1.92(avg. 1.80) without polar grnules.

This study was carried out to investigate occurrence and distribution of cellular slime molds by vegetation in Mt. Seorak. Eleven species were isolated from surface soil samples as follows: P. violaceum, P. candidum, P. purpureum, D. brefeldianum, D. minutum, D. delicatm, D. crassicaule, D. macrocephalum, D. firmibasis, D. polycephalum and D. implicatum. The dorminant species was D. brefeldinum. D. delicatum, D. implicatum, D. polycephalum and P. candidum of them were isolated rarely in Korea. It can be thought that these results were caused by characteristics of forest zone and geographical condition which Mt. Seorak is located at east side of central areas of Korea.

To conduct ethnobotanical study that grow wild in biosphere reserves or are traded in nearby traditional markets, we collected and analyzed traditional knowledge information on vascular plants that live in Mt. Seorak and Mt. Halla. As a result, the ethnobotanical plants investigated in Mt. Seorak consisted of 102 families and 489 taxa. The ethnobotanical plants investigated in Mt. Halla consisted of 118 families and 374 taxa. Both ethnobotanical plants from Mt. Seorak and Mt. Halla were most widely used for oriental medicine and treatment, and leaves were the most used organ. Differences in diversity by family of ethnobotanical plants inhabiting Mt. Seorak and Mt. Halla showed significant differences only in other use. The ethnobotanical plants traded at the traditional market near Mt. Seorak consists of 59 species in 34 families and 56 genera. The ethnobotanical plants traded at the traditional market near Mt. Halla consists of 102 species in 49 families and 94 genera. All ethnobotanical plants traded in traditional markets were most often used for oriental medicine and treatment, and stems were used most often in the traditional market near Mt. Seorak, and leaves were used most often in the traditional market near Mt. Halla.

There are marked differences in climate condition between east-facing slopes and west-facing slopes in Mt. Seorak (1,708 m). This study was conducted to find out the differences of benthic macroinvertebrate communities between both slopes of Mt. Seorak. Quantitative (Surber net; $30cm{\times}30cm$, mesh: 1mm) and qualitative (Hand net; mesh: 1mm) samplings ware carried out seasonally in each site which had 100-meter-high difference from November 2010 to November 2011. Most of the survey sites showed sound environmental conditions because they were located in the protection area of the national park. The benthic macroinvertebrates collected from all survey sites were composed of 158 species, 62 families, 17 orders, 7 classes and 5 phyla. DCA (Detrended Correspondence Analysis) ordination based on the abundance of benthic mactoinvertebrates showed that altitude was a major factor governing the structure of benthic macroinvertebrate community. There was no significant difference of the communities between both slopes.

The purpose of this research is reconstruction of annual precipitation based on Tree-ring series at Seorak mountain and examine its effectiveness. To do so we performed nonlinear time series characteristics test of Tree-ring series and reconstructed annual precipitation of Gangneung from 1687 to 1911 using Artificial neural network and Nonlinear autoregressive exogeneous input (NARX) model which reflects stochastic properties. As a result, Tree-ring series at Seorak Mountain shows nonlinear time series property and reconstructed annual precipitation series drawn from NARX is similar in statistical characteristics of observed annual time series.

The purpose of this study was to understand the factors influencing the decline and the patterns of changes in Abies nephrolepis populations on Mt. Seorak. We installed permanent quadrats in the areas of the Gwittagicheongbong (peak), Gwanmoneungseon (ridge), and the Seorak Falls and have monitored the community structure, population dynamics, radial growth, and vitality in the quadrats since 2009. Excluding the Seorak Falls, the three research sites showed a three-layer structure in which the low-tree layer forms the canopy. Major tree species were Khingan fir, Korean arborvitae, Mongolian oak, Erman's birch, and Korean maple. The significance of Khingan fir in Seorak Falls decreased from 45.3% in 2009 to 36.8% in 2018. The number of shoots ($DBH{\geq}5cm$) was highest at 1,800 individuals/ha and 1,700 individuals/ha at the Gwittagicheongbong 2 and the Gwanmoneungseon, respectively. The mortality rates over the past 10 years were very high, at 38.3% and 35.3%, respectively, in the Gwittagicheongbong 1 and Seorak Falls. The most stable inverse J-shaped distribution in the Gwittagicheongbong 1 area was shown in the size-frequency distribution of the Khingan fir populations. The average annual ring growth of the Khingan fir was 0.96 ~ 1.73 mm/year, and the ring growth tended to decrease in the areas of Gwittagicheongbong 1, Gwanmoneungseon, and Seorak Falls, where the vitality was low. If the monitoring process continues, it will be possible to obtain basic data for the conservation and management of subalpine vegetation.

The structure and dynamics of Korean red pine stands established in the riparian zone were studied in the Tsang stream in Mt. Seorak National Park, in east-central Korea. Pine stands were classified into four successional stages, the initial, establishing, competitive, and stabilizing stages, based on the age distribution of a dominant tree, Pinus densiflora, the vegetation stratification, and the microtopography of the riverine environment. The stages usually corresponded to disturbance frequencies, depending on the horizontal and vertical distances from the watercourse. Stands of the initial and establishing stages lacked tree or subtree layers, or both. As stands progressed through the developmental stages, soil particle size became finer and moisture retention capacity was improved. The stand ordination reflected the developmental stage, and the species ordination differentiated species specializing in relatively dry and wet habitats. The results of the analysis of vegetation dynamics provided ecological information which will be useful for understanding the developmental processes of vegetation established in riparian zones. Species diversity indices usually increased across developmental stages, following the typical pattern for successional processes. We discuss the importance and necessity of riparian vegetation in Korea, where most riparian forests have disappeared due to excessive human land use.
