Urban forest area in South Korea has been increased up to 20.8% of national land as of 2007 by the mergence of municipalities and counties. The rate of park and green tract among urban forest averages out to about 4% nationally but the Capital, Seoul, almost 105% level, not easy to split the two. Park and green has positive management system because of its infrastructure attribute and relevant security obligation standard while urban forest left alone with no such concerns. The most important reason of the negligence comes from institutional inertia although it is possible to be managed functionally by forest laws as like forests of park, landscape, wind and noise protection, and timber product. As a results, it reaches below than 92.64% of the national average level of the timber stockpile especially in the metropolitan areas and loses broad acres rapidly due to the easy conversion system to the urban land usage. Therefore, there must be required some alternative methodologies to conserve and foster it. The paper proposes the four urban forest management types and their control methods. The four types divide into conservation, foster, development, and reservation ones. Also it suggests the five furtherance tract types with the combination among the four earlier types, optionally having one of the six aim climaxes and recommends the standardization of operation design. The total green quantity index of urban forest also suggested by the weight method according to location and DBH class. The case study of the suggested model was executed on the Daejon Metropolitan area and its index calculated as 110.4% level compared with the acreage.

This study aims to examine the existing law-protected trees in the city of Daejeon and find out the way of creating urban small parks by utilizing them. To do this, this study reviewed previous research papers and scholastic writings, and surveyed present conditions and usage patterns of the 135 law-protected trees in the city of Daejeon.The result shows that the sites of 114 law-protected trees are possible to create as urban small parks and the sites of 42 trees, among them, have proper location and condition through the result of an evaluating sheet. To create urban small parks using the law-protected tree, considerations are as follows. First, the age, the origin, the tale, the cultural heritage, and so on should be carefully investigated through the scholastic research and survey. Second, systematical management system should be organized to maintain ecological sustainability. Third, each protected tree belongs to the community and the consciousness of citizens should be elevated to have a strong affection to them by educating and informing as a cultural heritage and a community symbol.
