The purpose of this study was to investigate and evaluate the state of School Forest Movement by the School Forest Committee of the ‘Forest for Life’, and to provide schools and social communities with alternative, for activation through foreign and domestic case studies. School Forest Movement is very important and has great effect on many aspects, such as the improvement of school environment, the expansion of environmental education in school, the enhancement of local membership and increasing participation of school community. School Forest Movement has expanded from 10 schools in 1999 for pilot implementation to 20 in 2000. Now, it Is broadly recognized that the movement should be expended nationally A few problems were observed through pilot implementation. School community has little consensus away member and hardly participates in the movement, and the process is often underestimated, comparing to the result. For activation of School Forest Movement, school community should be cooperate to local community. Especially, the stepwise execution of School Forest Movement should be well organized and School Forest Movement should be changed into a process-oriented movement for more participation of school community including students, teachers, parents and.

School forests, an important part of the urban forest, has diverse functions and plays an important role in artificial environment. It has three main functions: educational for children, ecological for nature, and cultural for residents. In spite of its diverse functions and roles, the actual conditions and achievements of school forests have not been correctly evaluated, resulting in institutional inertia. To improve these problems, this study was synthetically conducted by the post occupancy evaluation of users(residents, teachers and students) at school forests. This study can be summarized as follows: 1. The cognition and satisfaction level of school forests supported by private organizations was higher than those by local governments. Therefore, the establishment of a post management system of private organizations is more effective than the simple financial support of local governments. 2. The frequency of use of school forests by residents was higher than that of teachers. Their purposes were mainly to rest or walk However, teachers used school forests for nature observation and education. 3. In a survey of teachers about a reform measure and problems of school forests, the necessity of a post management system and financial security were significant requests. In addition, steady publicity and education, participant program, and incentives for teachers should be considered. This study is meaningful to systematically develop and activate the school forest movement. The integrated approach to the school forest movement reflects opinions of related users and is expected to become a useful foundation in studying about the improvement of city environments.

This study, with teachers form elementary schools in Chungju-si as its subjects, has investigated influence of school forest on satisfaction with school greenspace and environmental education. It has reached the following conclusions. As for recognition of and satisfaction of school greenspace there were meaningful differences between teachers form school forest model schools and ones from common schools, which was thought to be due to positive effects of school forest movement. It appeared that environmental education was carried out through audio-visual materials once a week in most schools. On the other hand, as for class places, 'classroom in parallel with outdoor class' and 'classroom education' appeared to be carried out most frequently in the case of school forest model schools, and 'classroom education' in the case of common schools. However, considering the fact that 'field learning' the most important element in environmental education, appeared to be carried out least frequently in both of the groups, which suggests that we should improve it for future through introduction of various field-experience learning programs. As a result of the survey of satisfaction with environmental education, some meaningful differences were recognized between school forest schools and common schools, and 'presence or absence of field learning spaces' was the most frequently answered reason for 'satisfied' and 'unsatisfied'. Thus, 'schools' and related institutions' enthusiastic efforts are needed for providing field-experience spaces where children can directly access to and explore into nature.

Transport of colored papers and decomposition of leaf litter of Quercus mongolica, Acer pseudo-sieboldianum, and Kalopanax pictus were investigated on three patches differentiated by aspect and understory in a temperate hardwood forest. Two patches are represented by dwarf bamboo (Patch SS) and herbaceous plants (Patch S), respectively, Iying on a south-west-facing slope. The other patch (Patch N) is located on a northeastfacing slope with herbaceous plants. Colored papers were placed on the patches to understand the pattern of litter movement on the ground. Papers were move dispersed in Patch S than in the other two patches. Some of the colored papers placed in Patch S moved upward. The results suggest that the litter movement is affected by aspect and that the leaf litter is retained by dwarf bamboo in Patch SS. Decay constant of Q. mongolica was significantly (p＜0.05) lower than those of K. pictus and A. pseudo-sieboldianum. Decay rates of Q. mongolica were significantly different between Patches N and S and between Patches SS and S (p＜0.05). On the other hand, decay rates of the other species were not significantly different among the three patches. The results suggest that aspect and understory exert an influence on redistribution and decomposition of leaf litter and that the effects could be different among the plant species.

With rapid economic growth, the urban environment has created a problem of human physical and mental illness. In order to solve these problems, urban forests have emerged as a way to mitigate the environmental risks through improving the polluted environment of the city and improve the quality of life. As the urban forests have expanded, the school forests movement has also been taking an important place recently. The study focused on the performance of school forests by comparing the perceptions among teachers and students about their functions. The questionnaire was composed of 4 questions concerning human matters, 10 questions for space recognition, 4 questions for thermal environment, 2 questions for health promotion, and 20 total questions for composition of survey items. The reliability of the school forest function, number of tree planting areas and quantities, the harmony of the planting, and the satisfaction of the school forest were analyzed in the questionnaire conducted by the school members. Although it does not recognize school forests, it has a positive response to the green space that is built outdoors. It is considered that outdoor education and environmental education are sufficient in school forests and green spaces. The results showed that the outdoor green space was more satisfactory when compared with the general school. Teachers and students' preferences were similar to 'seasonal changes' and' trees of various colors and shapes'. The reliability analysis between each item shows that the coefficient for cronbach's ${\alpha}$ was .700 to .834. The purpose of this study is to identify the perception of forest function among school forest members and to utilize them as a basic data in the future.

As populations inhabiting in natural ecosystem are fragmented by artificial barriers and habitats are destructed by development, extinction possibility of species is getting higher. It is necessary to design and to manage conservation areas and corridors considering animals' movement and migration for sustainable species diversity in present circumstances. 'Least-cost modeling' is one commonly employed approach in which dispersal costs are assigned to distinct habitat types and the last-costly dispersal paths among habitat patches are calculated using a geographical information system (GIS). This study aims to design ecological corridor using least-cost path method and to apply it to a regional ecological network considering movability of medium-large size mammals. This study was carried out over the metropolitan area, which has been deforested by rapid urbanization. Nevertheless there is connected with Gangwon province, Baekdudaegan mountain range and DMZ, considered where many forest species can migrate to this region. This study employs such an approach to develop least-cost path models for medium-large size mammals, have inhabited for this entire region. Considering those species, two forest areas as a source of species supply and forest areas more than 1,000ha are selected as focal forest areas. Movement and migration paths from species supply sources to focal forest areas are calculated by applying landscape permeability theory using land cover map, road density map and land slope map. Results showed least-cost paths from species supply sources to focal forest areas on two species. Wildcat and roe deer are different in some least-cost paths caused by their landscape permeability but paths show generally same specifics. The result of considering regional distribution of expected movement and migration paths to regional ecological network, low altitude mountains of western metropolitan area are evaluated important area for species connectivity. In national or regional levels ecological connectivity is essential to promote species diversity and to preserve integrated ecosystem. This study concludes that developing least-cost models from similar empirical data could significantly improve the utility of these tools.

Effects of forest thinning on community level properties have not been understood yet in Korea. We investigated regeneration patterns and trajectories after a disturbance by applying a chronosequence approach. Light availability, litter and woody debris cover, and species composition were determined for twenty 50 m line-transect samples representing a disturbance duration gradient (within 11 years). Environmental factors such as light availability and coverage of woody debris and litter changed abruptly after thinning and then returned to the pre-disturbance state. Although species richness was gained at shrub and ground layer in a limited way in both forests, cover of various functional types revealed diversity in their responses. Notably, Alnus firma stands exhibited a larger increment of cover in woody plants. Ordination analysis revealed different regeneration trajectories between natural and planted stands. Based on ordination analysis, rehabilitated stands showed movement to alternative states compared with natural ones, reflecting lower resilience to perturbation (i.e., lower stability). Our results suggest that community resilience to artificial thinning depends on properties of the dominant species. But to get more explanatory ecological information, longer-term static observations are required.

The purpose of this study is to survey and analyze the environmental awareness and attitude of elementary school students, adapting the CHEAKS(Children's Environmental Attitude and Knowledge Scale) for Korean elementary students, which is the valid-tested tools for children's environmental awareness and altitude. The subjects are 580 students from 6 elementary schools. The differences of the environmental attitude are surveyed and analyzed by environmental education activities, such as environmental activities in school and “the school forest movement”, and environmental awareness and concern. The results are as followings: First, the subjects replied that the environmental problems are very serious, such as atmospheric pollution(37.6%), water pollution(22.2%) and food waste(16.3%), but they are relatively optimistic of the future environment. Second, the verbal commitment subdomain and the affect domain are evaluated higher than the actual commitment subdomain, and the environmental issues of water, energy and recycling are considered more importantly than other issues such as environmental generals, pollutions and animals. Third, the grade and the sex have little effect on the environmental attitude, but the environmental education activities have great positive effect, such as the experience of environmental camping, the education of saving resources, waste separation and the experience of raising plants and flowers. Fourth, the students with high awareness and concern about the environmental problems have high environmental attitude. Especially, the awareness and concern on the flowers and plants have very strong correlation with environmental attitude, regardless of the subdomains. Finally, the students from the school participating “the school forest movement” have relatively positive environmental attitude. Particularly, the participation of students and the positive approach of the school have positively great influence on the students' environmental attitude in all of 3 subdomains and 6 environmental issues.

Riparian zone occupies not more than 5% of the total watershed area and can be considered in between the terrestrial and aquatic ecology as that does not fall under both of them. Unlike to common terrestrial plant that can e seen on other land, the riparian vegetation that exist in riparian zone can be classified into various groups because of their peculiar living form. The recognition of importance of terrestrial environment has considered the importance of natural river due to which even today, the movement throughout the world to retrograde the river development is taking place customarily. In this research, noticing the actual condition of the river management reality, the original capacity of river landscaping of Han river has been quantified grasping the actual condition of riparian vegetation from distribution area surveying and analysis. The objective of the research is to find out the river retrogression and maintenance methods based on the ecological environmental quality around the river by maintaining the river plants having high natural capacity and river planning method based on the harmony between conservation of river environment and use of riparian zone.
