As a serials of researches for the restoration model of evergreen broad-leaved forests, the restoration strategies of the case study areas were proposed. Restoration type of vegetation were classified into an improvement type and a reconstruction type and a reconstruction type for Wando(Island). Improvement type of restoration was suggested for Mokdo(Island). Quercus acuta community, Q. salicina community, Neolitsea sericea community, Castanopsis cuspidata var. sieboldii community, Machilus thunbergii community, Cinnamomum japonicum community, etc. were suggested as a restoration goal of vegetation for Sando(Island). Machlus thunvergii community was suggested as a restoration goal of vegetation for Mokdo(Island). Also the species restoration olan of the Wando(Island) was prepared for Quercus salicina of Fagaceae and Ostrya japonica of Betulaceae those which the natural distribution and population size were very limited. There was no species which needed for species restoration urgently at Mokdo(Island).

Forest vegetation of Choksangsan area in the Deogyusan National Park is classified into mountain forest vegetation. Mountain forest vegetation is subdivided into deciduous broad-leaved forest, valley forest, coniferous forest, afforestation and other vegetation. Including 103 communities of mountain forest vegetation and 8 communities of other vegetation, the total of 111 communities were researched; the mountain forest vegetation classified by physiognomy classification are 36 communities deciduous broad-leaved forest, 26 communities of valley forest, 10 communities of coniferous forests, 31 plantation and 8 other vegetation. As for the distribution rate for surveyed main communities, Quercus mongolica, Quercus variabilis communities account for 65.96 percent of deciduous broad-leaved forest, Fraxinus mandshurica community takes up 22.50 percent of mountain valley forest, Pinus densiflora community holds 63.27 percent of mountain coniferous forest holds. In conclusion, minority species consisting of Quercus mongolica, Fraxinus mandshurica, Quercus serrata, Pinus densiflora, and Quercus variabilis are distributed as dominant species of the uppermost part in a forest vegetation of Choksangsan in Deogyusan National Park. In addition, because of vegetation succession and climate factors, numerous colonies formed by the two species are expected to be replaced by Quercus mongolica, Carpinus laxiflora and Fraxinus mandshurica which are climax species in the area.

The purpose of this study was to find out how different types of land use around green belts affect temperature decrease effects. For this, temperatures within and outside of green belts were measured. Based on the collected data, the study analyzed the land cover status and temperatures within green belts, temperature decrease effects and the range of effects around green belts, and the correlation between trees and temperature decrease effects by way of regression analysis. As a result, areas of the high temperature within green belts were formed on paved surfaces, whereas areas of low temperature were formed around forests or water surfaces. In addition, deviation was bigger in the highest temperature than the lowest one for areas of Leeward around green belts, but in general, there was a tendency that temperature became low near to green belts. As for the relation between land cover rate and temperature, what was effective to temperature decrease included forests, pasture and water surfaces. On the other hand, the effects of temperature decrease varied depending on increase or decrease of land cover rates. As for the influence of the different land use types around green belts on temperature decrease effects, the Shakuzi Park showed relatively stronger effects than the Ageomaruyama Park.

This study was carried out to examine and compare the changes of inhabitation of soil microarthropoda after forest fire between different types of forest; i.e. the coniferous forest (Mt. Chocdae) and the broad-leaved forest (Samsinbong in Mt. Chiri). The individuals of soil microarthropoda found at the burned and unburned areas of Samsinbong and Mt. Chocdae were 12 orders in 5 classes, and individuals of Insecta and Arachnida 98% of them. In respect of classification groups, Collembola order was high at the burned and unburned areas of coniferous forest, while Acari order was high at the broad-leaved area. When classified by soil depth, the total number of soil microarthropoda individuals inhabiting at Samsinbong, the broad-leaved forest, was 25,342 and 37,350 at 1~5cm depth of burned and unburned areas respectively, while at 5~10cm depth the number turned out 9,722 and 15,906. Soil microarthropoda individuals of unburned area was 1.6 times higher than for the burned area. At the coniferous forest, the number marked 31,665 and 51,431, respectively for 1~5cm depth of burned and unburned area, and 10,189 and 13,202 for 5~10cm depth. Here also, the number for the unburned area was examined to be 1.4 times higher than for the burned area.

Currently, the natural monument system of Korea for naming and designation of natural monuments is based on "Chosun Natural Monument Conservation Acts for Treasure, Ancient Landmark, and Natural Beauty" enacted in 1934 during Japanese colonization period. The framework of natural monument system is still in effect, which is pointed out as a problem. The Dangsan forests and Bibo forests are Korean traditional cultural resources representing countryside of Korea. Cultural Heritage Administration follows and relies on the 'Limsu of Chosun' (1938), a report written by a Japanese, for naming and classification of natural monuments. A Dangsan forest at Yesong-ri was named "Yesong-ri evergreen forest" in 1938. They followed the naming system of "evergeen forest" until today. The objective of this study is to review the issues and problems of 'Limsu of Chosun' and natural monument naming system begun during Japanese occupation period, and suggest an alternative to the current situation where naming natural monument accordingly without discretion. Eighteen dangsan forests bibo forests were selected for examination and analysis. The names of the dangsan forests bibo forests were evaluated to find out whether various aspects of the forests are reflected in the name. The study suggests that many forests and old trees designated as natural monument should be named as "~Dangsan forest", "~Dangsan forest Bibo forest", or "~Dangsan tree" with consistency accordingly. The new names will bring a momentum to overcome the limitation of natural monument naming system continued since Japanese occupation period, and also enhance the value of Dangsan forests and Bibo forests as Korean traditional and cultural landscapes.

This study investigated the effect of forest type changes in Daegu, the hottest city in Korea, on the land surface temperature (LST). The LST change by forest type was analyzed by 2scene of Landsat TM image from 1990 to 2007. The land cover types were classified into 4 types; forest areas, urban areas, cultivated areas and other areas, and water areas. The forest areas were further classified into the coniferous tree areas and the broadleaf tree areas. The result of the statistical analysis of the LST change according to the forest type showed that the LST increased when the forest was changed to the urban area. The LST increased by about $0.6^{\circ}C$ when a broadleaf tree area was changed to an urban area and about $0.2^{\circ}C$ when a coniferous tree area was changed to an urban area. This was the temperature change as the result of the simple type change for 17 years. The temperature change was larger when considering both cases of the forest type being retained and changed. The LST increased by $2.3^{\circ}C$ more when the broadleaf tree areas were changed to the urban areas than when broadleaf trees were maintained. The LST increased by $1.9^{\circ}C$ more when the coniferous tree areas were changed to the urban areas than when the coniferous tree areas were maintained. The LST increased by $0.4^{\circ}C$ more when the broadleaf tree areas were destroyed than when the coniferous tree areas were destroyed. The results confirmed that the protection of broadleaf trees in urban forests was more effective for mitigating climate change.

This study was conducted to comprehend the breeding bird community of thirteen urban forests ranged in size from $0.63{\~}37.0$ ha and compare the species richness of streetscapes such as wooded streets, street trees, and green patches. In urban forests, among thirty-one species observed, two species of Pica pica and Parus major were observed in all study areas, but five species of Phoenicuros auroreus, Pericrocotus divaricatus, Eurystomus orientalis, Emberiza elegans, and Cettia squameiceps were observed only one areas. Number of species was high at urban forests of Manchon, Bonri and Chimsan parks distributed in peripheral area of city, that was low at urban forests Jungri, Igoksaengsu and Sinam parks located in the center area of city. We observed the nests at wooded streets and green patches, did not find at street trees. Number of species and density were significantly high at wooded streets than at street trees. Number of species was highly correlated with the area of forests, and srecies richness of bush-nesting guild was low. As the area of urban forests increase, species richness of bush-nesting and -foraging guild showed the relative low rate of increase than other nesting guild. Our results indicate that bush-nesting and -foraging guild of birds was not being provided with their good habitat at urban forests in Daegu city Among streetscapes, birds preferred to u9e the wooded streets and green patch as habitat and pathway in urban ecosystem.

This study carried out a phytosociological research by Z.-M. school's method describing vegetation structure and management solution about nutmeg tree's(Torreya nucifera ) forests. The nutmeg tree's forests have developed intervale and hills in warm-temperate evergreen broad-leaved forests zone. The nutmeg tree's forests composed 50 familly, 80 genus, 88 species divided two syntaxa(typical sub-community, Arachniodes aristata sub-community) by species composition and correspond to habitat condition. The nutmeg tree's forests show a uniform forest's structure which composed 3~4 layer of sub-tree and shrub. And it was worthy of special mention which characterized diagnostic species of Camellietea japonicae in the warm-temperate evergreen broad-leaved forests. In case of forests floor, were a high rate in order of Ophiopogon japonicus, Polystichum tripteron, Arisaema ringens. And Oplismenus undulatifolius which represent mantle communities as well. This indicates that the nutmeg tree's forests are exposed by humman effects sustainedly. The nutmeg tree's young trees appeared a high rate at half shade and shade. The vigorous tree species have to spacing cutting instead of the heavy thinning that consist in with a shout of declining astructur and function of the forest ecosystem for maintaining a nutmeg tree's forests. And we suggest for the density regulation of the sub-tree and shrub. In conclusion, need to the continuous monitoring about the vegetation structure and management solution for the sustainable nutmeg tree's forests.
