Synopsis (short abstract) Oak mushroom is one of the most popular edible mushrooms in Asia, including Korea, China, and Japan. It has been grown by log cultivation method using oak tree species in Korea since the 1950s. However, the decades of reckless deforestation of oak trees for oak mushroom grow has recently led to the need for protection in Korea's forests to prevent oak resource depletion. As of 2019, there were 3,764 log cultivation farms in Korea and the total amount of oak mushroom log was 39 million. Average cultivation period is 3 years and 12 million oak logs are needed every year. According to a survey of shiitake growers, 87.3% of the respondents said that the most preferred species were Sawtooth oak(Quercus acutissima Carruth), and the most preferred diameter was 16 to 20cm, with 43%. The distribution status of oak trees across the country was found to be 1.44 million hectares with growing stock of 160 million m3, and the preferred Sawtooth oak was 91,370 hectares with growing stock of 10 million m3. When oak trees which are between 20 and 30cm in diameter at breast height are cut, they are the most effective use of resources, the available quantity for log cultivation was 8 to 11. However, if the diameter at breast height exceeds 30cm, the available quantity decreases. The number of Sawtooth oak trees that can be produced as logs for oak mushroom cultivation is 321 million, and the annual actual demand is 12 million, so the supply is sufficiently sustainable in the future. However, in the actual field, there are many restrictions on the use, such as the location accessibility, possibility of collecting felled trees, and possibility of using oak mushroom cultivation. It is expected to continuously produce Sawtooth oak logs for shiitake cultivation every 15 to 20 years due to its rapid growth compared to planted land, if the area where more thanv 1,200 oak trees are distributed per 1 hectares is harvested and then maintained through reproduction by sprout.

    Satellite remote sensing-based forest resources assessment methods for effective management and sustainable development of forests by generation of information on forests and trees outside forest cover

    Satellite based remote sensing methods have proved to be an effective and scientifically proven method for managing and conserving forest data and resources at periodic time intervals. The forest resources monitoring methods provide useful data to forest managers for sustainable forest management at different scale and forest management units. Over the years the scientific management of forest have been a subject globally discussed incorporating the role of environmentalist, conservationist and communities associated with the forest. It has been an unhidden fact that forests have suffered tremendous pressure in developing countries on the pretext of development. It is through effective monitoring and communication of forest information and knowledge that the concerned provincial governments are forced to take remedial measures for protecting the forests. Apart from the government owned forests, termed as Recorded Forest Areas(RFA) in India, Trees outside forests(TOF) are well acknowledged as an important component of forest resources. The ToF, which basically exist as block, linear and scattered plantations on earth are captured using LISS-III sensor of Indian Remote Sensing Satellite. For the national level scale mapping, all patches of area 1hectare and above are considered for estimation. For mapping of ToF patches of size between 0.1-1hectare, high resolution data from LISSIV sensor(5.8metres resolution) is analyzed. It has been now a well-established fact that trees outside RFAs, although in small proportion, contribute significantly to forest conservation and meeting the demand of people towards minor forest produce, firewood etc. The exercise on forest change detection using a hybrid method, is effective in identification of significant forest change. The assessment of forests and ToFs using satellite data and advance image processing tools may be helpful in effective management and long term sustainability of forests in developing countries.

    Lessons learned from the ASEAN-Korea green partnership in the restoration and sustainable management of degraded forest ecosystems for the Philippines

    This paper presents the lessons learned from the Republic of Korea financed ASEAN-KOREA Environmental Cooperation Project (AKECOP) about two decades of experience in creative collaboration in research and human resource development in the restoration and sustainable management of degraded forest ecosystems in the ASEAN region. The Philippines and nine other participating ASEAN member states (AMS) have learned valuable lessons from the various innovative collaboration strategies employed by the Project. Participatory project management was adopted to ensure project relevance, quality, reliability and equitability and maximum impact. Research and development in-country and cross-cultural collaborative modes were tried and found to be effective strategies in enhancing research outputs and in facilitating research process learning experiences. Cross country exchange visits to locally successful restoration sites were found to be effective schemes for information exchange and technology transfer. And needs-oriented short training programs and graduate studies at the MSc and PhD level were effective strategies in building a pool of high- level expertise in forest restoration and SFM. However, the most valuable lesson from the Project's experience in creative collaboration is that SUCCESS in smaller collaborative initiatives such as AKECO P can inspire the creation of larger institutional partnerships such as Asian Forest Cooperation Organization (AFoCO). As a way forward, the participating AMS have arrived at a consensus that AKECOP should continue to serve as a platform for regional collaboration in SFM considering its notable part achievements. In line with the ASEAN "GREEN VISION" and its journey towards regional integration, AKECOP is envisaged to re-align its innovative strategies to the changing needs and challenges in the sustainable management of a healthy and productive forest ecosystems in a new world order threatened by the scourge of the COVID 19 crisis.

    A study on tree species and crops of agroforestry according to ecological geographic map in North Korea

    This study was conducted to analyze the appropriate tree species and crops according to agroforestry target sites in North Korea based on ecological geography and site properties with the purpose of preparation of technical cooperation on agroforestry, one of the main agendas of the Inter-Korean Forest Cooperation Subcommittee. The agroforestry is one of the methods for forest restoration that satisfies both North Korea's fuel and food shortages and the restoration of deforested land and it began in 2003. To this end, the ecological geographic map (13 regions and 4 zones) of North Korea was made by using satellite images with North Korean journals. The target sites for agroforestry was classified according to 18 site conditions depending on 3 site characteristics (soil depth, relative location, slope), and divided as short-term and long-term target sites depend on agroforestry management period. And then, appropriate tree species and crops for agroforestry are selected according to them. By regions within the same zone, tree species and crops were mostly similar, but compared to each zone, they differed. This seems to be because the geographical climatic characteristics reflected in the ecological geographic map vary greatly from zone to zone. Through this, it is expected to provide information that can be more efficiently implemented through analysis of the target sites needed for application of agroforestry and needed for application of agroforestry management and the combination of suitable species and crops.
