ArticleThe change in forest productivity and stand-dynamics under climate change in East Asian temperate forests: A case study from South Korean forests
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The velocity and impact of climate change on forest appear to be site, environment, and tree species-specific.The primary objective of this research is to assess the changes in productivity of major temperate tree species in South Korea using terrestrial inventory and satellite remote sensing data. The area covered by each tree species was further categorized into either lowland forest (LLF) or high mountain forest (HMF) and investigated. We used the repeated Korean national forest inventory (NFI) data to calculate a stand-level annual increment (SAI). We then compared the SAI, a ground-based productivity measure, to MODIS net primary productivity (NPP) as a measure of productivity based on satellite imagery. In addition, the growth index of each increment core, which eliminated the effect of tree age on radial growth, was derived as an indicator of the variation of productivity by tree species over the past four decades. Based on these steps, we understand the species- and elevation-dependent dynamics. The secondary objective is to predict the forest dynamics under climate change using the Perfect Plasticity Approximation with Simple Biogeochemistry (PPA- SiBGC) model. The PPA-SiBGC is an analytically tractable model of forest dynamics, defined in terms of parameters for individual trees, including allometry, growth, and mortality. We estimated these parameters for the major species by using NFI and increment core data. We predicted forest dynamics using the following time-series metrics: Net ecosystem exchange, aboveground biomass, belowground biomass, C, soil respiration, and relative abundance. We then focus on comparing the impact of climate change on LLF and HMF. The results of our study can be used to develop climate-smart forest management strategies to ensure that both LLF and HMF continue to be resilient and continue to provide a wide range of ecosystem services in the Eastern Asian region.

DocumentType classification of damaged forest in the Island Areas, west coast of Korea and analysis on the charaterisitics of restoration sites
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The study aims to produce basic data which can be used in establishing a forest restoration plan in the island areas of the west coast of Korea. First, the damaged type of island area was determined based on the GIS data, and a field study was carried out on 110 of the extracted damaged areas for classified type of forest restoration sites with the Forest Restoration Guidelines of the Korea Forest Service. As a result of the analysis, the total number of islands on the west coast of Korea was 1,977 (254,258 ha), with 323 (248,258 ha) of manned islands and 1,654 (5,871 ha) of uninhabited islands. 11 damage types (590 locations) were extracted through video reading of 2,774 suspected deforestation cases (5,431 ha). The field survey was conducted on 110 locations on 44 islands which were reclassified into 14 damage types. Among the types of forest restoration target sites, the types of damage (12 places) that require restoration of the underlying environment are classified into three categories: facility sites, soil and stone ground, and landslide-damaged sites. it was found to be a man-made damages concentrated in private land with high development pressure, especially in Incheon and Jeollanam-do province by region. Vegetation restoration included 9 different types of damage (96 sites) and it was analyzed that Incheon Metropolitan City and Chungcheongnam-do province have a high rate of grassland and livestock grazing land and Jeollabuk-do province with high distribution of grassland and non-stocked forest land. And Jeollanam-do province had 8 types of damage, relatively more various types of damage confirmed compared to other areas. Habitat and species restoration are required for bird colonies and coastal wetland types (one site, respectively). Plants are dying due to fishery and neglected household waste and bird excrement, therefore it shall be considered from the habitat restoration point of view. The research results are expected to be used in extracting target sites for forest restoration plan and a criteria to find the target sites suitable for the characteristics of damaged areas.

DocumentSystem and characteristics of forest trail in South Korea
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.As an improvement in the national income and leisure time drives more people to visit the forest trail for the purpose of recreation. One of the representative characteristics of establishment of forest trail in South Korea is that it focuses on the Baekdudaegan, which is the ridgelines of Korean Peninsula and ranges from Mt. Baekdu to Mt. Jiri, and Jeongmaek which is the continuous ridgelines of Baekdudaegan over 100km. The Sangyeongpyo, which is a traditional classification system of Korean Peninsula, demonstrates the concepts of Baekdudaegan in Korean Peninsula and Jeongmaek. However, only South Korea section of Baekdudaegan is available to walk on due to the situation of Korean Peninsula despite that it ranges between the entire Korean Peninsula. The total length of forest trail placed on the South Korea section of Baekdudaegan and the 9 sections of Jeongmaek is 701 km and 2,154 km, respectively. ‘Forest cultural recreation Act’ defines the Korean forest trail as a walkway established on the forest for the activities such as hiking, tracking, leisure sports, visit or recreation, healing. In the past, the most of Korean forest trail provided the basic vertical hiking culture based on Baekdudaegan mountain system. However, as the increase in recreational activities and needs for different activities in forest trail raised recently, the use type of forest trail has ranged from enjoying the surrounding area of mountain to leisure sports, healing and enjoying the scenery. Based on the change in the use type of forest trail, in 2011, the Act specified the concepts of forest trail into 6 types such as trails for hiking, tracking, forest leisure sports, visit or recreation, healing. 10 thousand forest trails in total are currently established in Korea and their length sum up to 40 thousand km. 93.5% of these trails are for hiking and they occupy 81.8% of the total length of all forest trail in South Korea.
