DocumentAnalysis of tree taxa found in site of forest restoration projects in Korea
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The monitoring data conducted on 72 forest restoration sites in Korea that have implemented the projects from 2008 to 2020 has been analyzed to identify the trees that are mainly found in those sites. First, taxa with overlapping appearances by site were excluded and a list including growth types was developed. The frequency of appearances by taxon was identified by classifying 27 sites according to the forest landscape and ecosystem management area in order to prevent regional bias of the sites and the main tree species were identified through laws and references. The research has identified 225 taxa trees throughout the entire research sites. In terms of growth type, in the following order, deciduous 187 taxa (83.1%), evergreen 34 taxa (15.1%) and semi-evergreen 4 taxa (1.8%). Arboreal was 121 taxa (53.8%), shrub 77 taxa (34.2%) and vine 27 taxa (12.7%) in the said order. The frequency of appearance in the 27 sites is in descending order: Lespedeza bicolor Turcz., Rubus crataegifolius Bunge, Pinus densiflora Siebold & Zucc. etc. The main tree species were 59 taxa (26.2%) of native plants for forest restoration designated by the Korea Forest Service, 49 taxa (21.8%) of trees recommended for reforestation, and 12 taxa (5.3%) of temperate evergreen broadleaf trees. The study result would contribute to identifying the problems of the tree taxa appearing in the restoration sites and to select trees for the future restoration projects.

DocumentMid-term demographic dynamics in stem exclusion stage of beech forest in Ulleungdo Island, South Korea
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Long-term observation on forest development processes after various disturbances provides the baseline information such as management options including restoration. We examined changes in forest structure and function and patterns of demographic rates (2009-2019) in young beech forest in Ulleungdo Island, South Korea. Change in mean stem density revealed bell-shaped form and growth rate in mean above ground biomass decreased. By predominant stem density and biomass, beech population exhibited strong influence for whole community patterns. Size distributions of tree community revealed influences from maturity and restrained recruitment of trees. Demographic rates showed interesting patterns because recruitment (from 1.3 in to almost 0) and mortality rates (from 0 to 1.8) have abrupt turnover in 2015. Disturbance events from soil deposition originated by heavy rains after 2017 increased stochastic events of tree death (from 0 to 15%). Our results suggest that in stem exclusion stage there were dramatic turnover between stem recruitment and mortality. In addition, disturbance events have influenced to demographic rates by increasing stochastic tree motality. Keywords: Biodiversity conservation ID: 3622286 -
ArticleKorea-Indonesia peatland restoration cooperation: Challenges and opportunities to recover degraded peatland ecosystem in Londerang peat protected forest
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Indonesia harbors around 24 million hectares of peatland or approximately 23% of the world’s tropical peat ecosystem. Some of them can be found in Londerang Peat Protected Forest that belongs to Jambi Province which has suffered from the repeated forest and land fires that were recorded both in 2015 and 2019. Several concerns have arisen from this disaster, including the degradation of the peatland ecosystem and wide-ranging socio-economic issues at the regional, national, and international level, and raising concerns from the global society. In response to these issues and to strengthen the international cooperation between the Government of the Republic of Korea and the Republic of Indonesia, both parties established joint cooperation titled “Restoration of Burnt Peatland in Jambi”. The project was carried out through several activities. To maintain the groundwater table, the hydrological function is restored by constructing canal blocking and water table monitoring system. Revegetation is carried out by planting native peatland species with a high survival rate. Ten villages were revitalized in order to improve their socio-economic welfare by encouraging active participation from local communities. In addition, a peatland education center was built to raise public awareness about the significance of the peatland ecosystem. This paper aims to identify the challenges and opportunities of the Korea-Indonesia peatland restoration project in Jambi province. Qualitative descriptive approach was used along with literature study. The result showed that active participation and effective communication between all stakeholders played a huge role in the successful implementation of international forestry cooperation.
