This study was carried out to investigate members' affiliation motive to Forest Management Cooperative which is the main managemental body of the private forests and management problems of the organization to find out a solution of the problems and set active promotion plan. The questionnaire about the management of the cooperatives was done by interviewing the members at Seoha Inboh Forest Management Cooperative in Ulsan-gun, Kyongsangnam-do and Sechong Forest Management Cooperative in Chinan-gun, Chollabuk-do from July to August in 1993. Twenty interviewees were selected in the order of their business quantity on the forest from the members who reside in their villages. Integrated matters such as were members' affiliation motive, benefit after their affiliation, management system, incorporation of the organization and other issues concerning to managemental plans questioned. During the survey period, other data about management of the cooperatives were collected from the related organizations and opinions of every president of nine cooperatives in the investigated regions. The majority of the members agreed that the cooperative is an independent forest organization and evaluated the Training and Extension Service Center high. However, their participations in the cooperative such as forest technical training and cooperative forest management were low since they have not earned any income from their forest management.

This study attempts to analyze the relationship between forest volume and age based on 5th NFI data and spectral characteristics of satellite imagery using ASTER sensor in Korea. Forest stand volume and age had the negative correlation with the spectral reflectance in all of the band (Blue, Green, Red, SWIR). With increasing of stand volume and age, spectral reflectance decrease. The spectral reflectance of band1 showed the highest correlation between stand volume and spectral reflectance among the VNIR wavelength. The spectral reflectance band 1, 2 (visible wavelength) and stand age have high correlation compared to other bands. The correlation coefficients between forest volume and vegetation indices have low relationship. This result indicates that the reflectance of blue band may be important factor to improve the potential of optical remote sensing data to estimate forest volume and age.

Site index is the essential tool for forest management to estimate the productivity of forest land Generally, site index equation is developed and used by relationship between stand age and dominant tree heights. However, there is a limit to use the site index equation in the application of variable ages, environmental influence, and estimation of site index for unstocked land. Therefore, it was attempted to develop a new site index equations based on various environmental factors including site and topographical variables. This study was conducted to develop regional site index equations based on the relationship between site index and soil factors for Pinus densiflora. Environmental factors that obtained from GIS application, were selected by stepwise-regression. Site index Equation was estimated by multiple regression from selected factors. Four environmental factors were selected in the final site index equations by stepwise regression. It was observed that coefficients of determination for site index equations were ranged from 0.34 which seem to be relatively low but good enough for estimation of forest stand productivity. The site index equations developed in this study were also verified to be useful by three evaluation statistics such as model's estimation bias, model's precision and mean square error type of measure.

Private forestland in Korea occupies about 48 percent of the total land area. But, the ownership size is too small to expect self-supporting management of forestowners. In order to improve individual management of the small-sized forest through the to the state of self-support, a cooperative forest management has been demanded, enlargement of the size of the management units by combining the different individual management units. The cooperative management of the private forest is to combine forestry production factors such as forestland, labor-power, and capitals according to the agreement. For the cooperative forest management, a proper plan should be established and well-trained working-crew should be produced. In addition, forestry facilities should be provided and operated jointly. Though the cooperative forest management by owners is considered to be favorable theoretically, it is difficult for forestowners including many nonresidents to organize the forest management cooperatives without outside help. Therefore, intensive pulblication and extension programmes are required and a financial support by the government should be followed.

The Yangsan Forest Management Station (YFMS) of Korean German Forest Management Project (KGFMP), working with the 6 legal villages of Uljugun, Kyongnam, led the forest owners in the area to organize the Forest Management Cooperative (FMC) voluntairily for improvement of private forest management and fostered it as a model from May 1975 to Apr. 1984. YFMS sent out FMC a forest manager as a forestry expert carrying out the leading extension program at the equal position with forest owners and gave FMC financial, administrative and technical assitances. During the 6 years from 1977 to 1982, 4 FMC were founded and are being operated democratically. 228 forest owners have taken the membership of their own free will and the forestland of the members covers 2,567 ha equivalent to 57% of the total private forest in the area. During the period the total area of the planting and tending is 4,185 ha, this means that a member executed 3.1 ha of forest operations per year in average, showing the high willingness on forest operations. In addition the joint works have resulted in the joint properties equivalent to 27 million Won and it will be an important foundation for operation of FMC which is a forest owners's cooperative organization for improvement of private forest management in this area. The total expenditure spent for the fostering of FMC amounted to 497,587 thousand Won and 58% of them were charged from KGFMP funds, 27% from the forest owners and 15% from public funds. The expenditure for investment was 273,104 thousand Won and 59% of the sum were appropriated as subsidies at the national level. The forest owners charged 43% of that and this means that each member invested approximately 100 thousand Won to his forestland per year in average. For the extension program 169,503 thousand Won were spent and it can be explained that 5,885 Won were spent per ha a year. The organization of FMC operated autonomously in a democratic way and the horizontal and leading extension system, which aspects the human rights, were very much effective in fostering the cooperative organization of forest owners for improvement of private forest management.

The object of this study is to identify the factors that is making and promoting cooperation for the unified forest fire administration, and then introduce cooperation process and cooperation manual for an effective forest management. For this purpose, the case studies were carried about "The East Coastal Forest Fire Administration Center" and "The Forest Fire Administration Center in Mt. Jiri Area" to have obtained excellent results by cooperation among administrative districts, and cooperative factors were extracted through analyzing each steps. That is, cooperation steps were divided into 4 steps of Initiation, Planning, Implementation, Benefiting, and in-depth interview and questionnaires were carried for extracting cooperation factors by each step for the unified cooperative forest management system. And with AHP analysis, essential four factors were extracted by each step based on priority order. Finally with the base of the essential 4 factors by each step, the cooperation process and manual appliable to forestry cooperation project were developed. This will be a guideline in order to achieve successful forest administrations through the cooperation among local administrative governments.

This research was carried out to understand the actual condition of Forest Management Agency System, Cooperative Forest Program and People's Forest Program with Public Participation and to boost the program. To carry out a quantitative survey among selected 5 Regional Forest Service and 27 National Forest Office, we investigated the activity-awareness concepts of officers on Importance, Performance, and problems of program. As a results, the difference of understanding on National Forest Management System involved with the results of agreement achieved. Also most serious problem of Forest Management Agency System were the shortage of participation will and the limitation of security benefit. The prime reason for the program problem is lack of investment in People's Forest Program. The final results on survey of National Forest Management System with the Importance and Performance as followed. It indicated that I(Keep Up Good Work) have 5 Factors, II(Concentrate Here) have 2 Factors, III(Low Priority) have 6 Factors, and IV(Possible Overkill) have 2 Factors. Base on above investigation, we finally suggest that new organization exclusive responsible for the improvement of management and encouragement of Build Transfer Operate.

In the United States, forest administration is a constantly changing complex of policies, programs, and management regulations. Forest administration is the product of a brief but tumultuous history during which much of the forests which once covered half the land were coutover for farms, industry, and cities. In the last 15 years, forest administration has been increasingly dominated by concerns for maintaining an ecological balance. Current forest administration is deeply rooted in the American traditions of decentralized federalism and free enterprise, yet combines state socialism and private capitalism. The major elements of U.S. forest administration consist of : 1) programs and policies on taxation, professional education and research, and "cooperative forestry", 2) state controls on forest practices for privately owned lands, and of federal policies and regulations for the management of federal lands. The federal Forest Service has played a lead role in developing and implementing national forest policies and programs. Since the end of World War II, the national forests managed by the Forest Service for multiple use have provided and ever growing fraction of domestic timber needs. In the coming decades, cultural and social trends may force a change in management policy on federal land, reducing the importance of timber harvesting in relation to amenity values.

The purpose of this study is to provide the basic information for the early enforcement and extension of the improvement project of management scale of private forest land by understanding the characteristics of forest owners, who have an influence on the participation of the project as one of the private forest management vitalization plans. To achieve this goal, a questionnaire survey targeting 373 forest owners was conducted and analyzed by Binary-Logistic Regression. The variables for binary-logistic regression included gender, age, academic ability, occupation, income, residence, purpose of forest ownership, and status of cooperative membership. As a result of the analysis, 267 forest owners (71.6%) of total 373 forest owners have the intention to participate in the scaling project for private forest management. The rest of forest owners (106 forest owners, 28.4%) would not be willing to participate in the project. As a result of binary-logistic regression, the most important variables, which have an impact on the participation of private forest management scale improvement project, are age, job and forest own purpose.

Total 183 private forest owners in Chungnam-Do were surveyed in order to analyse the attitudes toward cooperative forest management and to find out the relationship of the attitudes with such socio-economic variables as owners' socio-economic status(SES), age and educational level. Major findings of the study are summarized as follows:- 1. Only 17.5 percent of the owners regards the cooperative management as a desirable alternative for the management of private forests. Significant difference of their attitudes is recognized only among the classes of the educational level. 2. About one-third of the owners wishes to participate to a cooperative, if established. The owners' intention of participating is positively related to the degree of S.E.S. and educational level, but negatively associated with that of age variable, and the differences among the classes of all variables are significant at the 0.01 or 0.05 levels. 3. More than half of the owners desires to have limited cooperatives, in which the members themselves manage their forest land with some management aspects being handled by the cooperative such as procurement of seedlings, protection measures, and marketing. The difference of responses among the classes of educational level is significant at the 0.01 level. 4. The owners, who agree with the idea of voluntary membership in the cooperative, are about 45 percent of the total. Significant difference is found only among the classes of the S.E.S. variable. 5. Nearly 60 percent of the owners wants to have self-help cooperative organizations. Significant difference of responses is recognized only among the classes of the age variable.
