Total forest growing stock and growing stock per ha in Korea are $470\times10^6m^3\;and\;73m^3$, respectively. Those figures mean that forest growing stock was increased 4.7 times more during last 30 years. The annual production of forest biomass comes from forest tending executed by Korea Forest Service was estimated about $1.07\times10^6m^3$ M/T, which was equivalent to $0.45\%$ of total imported crude oil of Korea at 2002. The production is expected to increase and reach up to $1.9\times10^6 M/T$ till 2008. The analysis of economic feasibility showed that the production cost of wood chip(134,786Won/T) was about 30,389 Won/T higher than heat value of wood chip, 104,397 Won/T estimated from that of kerosene. For the promotion of forest bioenergy utilization, more efforts need to be given for the education and public relations to induce publicity a willingness-to-pay for the environment friendly fuels under the good understanding for the use of bioenergy. In addition, we need to provide a community-based biomass utilization program by region to allocate the role of each participant and to increase the profitability of bioenergy.

It is important to understand the patterns of forest fire in terms of effective prevention and suppression activities. In this study, the monthly forest fire occurrences and their burned areas were investigated to enhance the understanding of the patterns of forest fire in Korea. The statistics of forest fires in Korea, 1970 through 2005, built by Korea Forest Service was analyzed by using time series analysis technique to fit ARIMA models proposed by Box-Jenkins. The monthly differences in forest fire characteristics were clearly distinguished, with 59% of total forest fire occurrences and 72% of total burned area being in March and April. ARIMA(1, 0, 1) was the best fitted model to both the fire accurrences and the burned area time series. The fire time series have a strong relation to the fire occurrences and the burned area of 1 month and 12 months before.

This study examined the attitudes of the Korean forest policy interest groups toward the new environmental paradigm and resources management paradigm which were emerged in western societies. The 1st survey was conducted for five interest groups (forest owners, timber industries, members of the Korean Alpine Club, members of the Korean Natural Parks Association, forestry experts) in 1995, and the 2nd survey was conducted in 2006 for three interest groups (forest owners, members of the Forest for Life, members of the Baekdudaegan Preservation Society). The survey results show that there are significant differences in attitudes and beliefs toward the new environmental and resources management paradigms among groups. The environmental conservation groups such as the members of the Alpine Club, Nature Parks Association, Forest for Life, Baekdudaegan Preservation Society favor the NEP and NRMP more than those of traditional forestry related groups such as forest owners and timber industries. But, there are no significant attitudinal changes among forestry related groups. This research provides valuable insights into understanding the attitudinal positions of the interest groups toward forest resources management and policy formulation in Korea.

There has been a conflict over the use of private forest in Mt. Jiri National Park among the stakeholders. Therefore, the purpose of this study is to define each stakeholders' recognition difference about value and conflict of Mt. Jiri National Park and find the possibility of creating agreement point for solving conflict. For the purpose, the study performs factor analysis on the value of national park and conflict factor and abbreviates them to 4 factors respectively. The study classifies and compares the recognition difference among the stakeholders with t-test and Duncan multiple comparison. The result of this study is that village residents, Korea Forest Service and local autonomy share the same recognition about the value of national park but National Park has different recognition. Regarding the conflict, National Park, Korea Forest Service and local autonomy share the same recognition but village residents have different recognition. Regarding the organization of conference as a direction to solve conflict and its reason, all of the stakeholders share the same recognition. It is necessary to adopt clear standard for the use of forest and apply the different execution of regulation to each area.

In order to organize a new checklist for endemic vascular plants of the Korean Peninsula, 358 taxa of the Korea Forest Service and 375 taxa of the National Institute of Biological Resources were reviewed. In addition, the names of previously published endemic plants above the rank of variety were checked up to 2016. From the two lists, a total of 444 taxa were identified. Among them, 289 taxa were common on the two lists, but 69 and 86 taxa were listed only by the Korea Forest Service and by the National Institute of Biological Resources, respectively. Taxonomic documents including journal papers and dissertations were examined with regard to the 444 taxa. In some cases, opinions of Korean experts in this field were also reflected. From the results, 312 taxa in total were recognized as plants endemic to the Korean Peninsula, while 132 taxa could not be included on the endemic list. On the other hand, 48 taxa, none of which existed on the two lists, were newly listed. In conclusion, the new checklist of vascular plants endemic to Korea was confirmed, with a total of 360 taxa consisting of 64 families, 172 genera, 297 species, 4 subspecies, 51 varieties and 8 hybrids. The new common name Halla-seol-aeng-cho is given to Primula farinosa L. subsp. modesta (Bisset & S. Moore) Pax var. hannasanensis (T. Yamaz.) T. Yamaz. Sillaphyton Pimenov (Deok-u-gi-reum-na-mul-sok) is newly identified as a genus endemic to Korea. However, Pentactina Nakai could not be included on the list of Korean vascular endemic genera.

Global attention to the greenhouse gas emissions from deforestation and forest degradation is increasing. There is a growing recognition of reducing emission from deforestation and forest degradation plus (REDD+) as an effective way to reduce greenhouse gas emissions in the forestry sector. The Republic of Korea is implementing REDD+ pilot projects in four Southeast Asian countries as part of its efforts to reduce greenhouse gas emissions. This study evaluates countries with the potential to become priority partner countries for Korea's REDD+ programs, using the following five criteria: The first criterion is that a country should include the forest sector and REDD+ in its national plan for reducing greenhouse gas (GHG) emissions. The second and third criteria refer to an average forest coverage rate of over 44% and a forest change rate of over - 0.1%, among the countries with forest cover of more than 10 million ha. The fourth criterion is that the country should meet the Forest Reference Emission Level requirements, one of the four elements of the Warsaw REDD+ Framework. The fifth criterion is that the country should have bilateral relations with the Republic of Korea in forestry while at the same time be a partner country for cooperation on climate change as well as a REDD+ pilot country. Based on our evaluation, we conclude that the first priority countries are Indonesia, Cambodia, and Myanmar. The second priority countries include Brazil, Ecuador, and Peru. Finally, the third priority countries are Columbia, Congo, and Mozambique. This study suggests that for the selection of priority partner countries, Korean REDD+ programs should center on existing REDD+ pilot countries.

The prototype of forest fire management system on Web was studied. In the architecture of this system, one of the most important concerns is to handle load upcoming to Web Server so that it provides Web service without any delay or failure. In order to solve this problem, the agent is designed on dispatcher in a Web server cluster and implemented to distribute load dynamically by considering the information related to load coming to the Web Server such as the number of connection to the Map Server. The proposed forest fire management system has user-friendly interface with the GIS mapping functionality by selecting Map Objects Internet Map Server (MO IMS) as Map Server and is implemented using Java as programming language.

The Japanese larch (Larix kaempferi [Lamb.] Carriere) is a major timber species in Korea. However, studies on bucking rates and merchantable logs of this species are insufficient in South Korea. To bridge these gaps, in this study, the bucking rate of Japanese larch (Larix kaempferi [Lamb.] Carriere) was computed and the number of long logs and merchantable log volumes were analyzed. Sample trees were bucked according to the log grade for trading, and collected from a forest field in Gangwon Province. The bucking rate of all Japanese larch logs was >89%. The highly profitable 2-4 logs of 3.6 m length from trees with ≤30 cm diameter at breast height (DBH) and 5-6 logs with ≥34 cm DBH were produced. The bucking rate of long logs was >84%; thus, Japanese larch was found to be suitable for the supply of high-grade timber. Additionally, to follow reasonable wood supply plans, merchantable volume tables were offered based on 3.6 m-long number of logs and small-end diameter classes. Understanding the proportion of merchantable log volumes, bucking rates, and the number of long and short logs has large-scale applications in practical forestry.
