  • Marine activities are becoming more diverse and extensive due to recent social developments, exceeding the environmental capacity of the marine ecosystem. The resilience, resistance, and constancy of marine ecosystems are being damaged or degraded. This prevents the ecosystem from functioning properly, leading to a decline in ecosystem services and value. As a means of returning the damaged ecosystem to health, more and more people are interested in restoration. At a time when restoration projects are gradually expanding, various problems that may arise when implementing the Sea Area Utilization Consultation and Impact Assessment for restoration projects need to be checked, in addition to confirming the direction to be pursued. Therefore, in this study terms related to restoration from research papers and reports were summarized, and the status of the Sea Area Utilization Consultation related to restoration projects and the status of the restoration project were reviewed. In addition, problems with Sea Area Utilization Consultations were considered through a case study to ensure the successful execution of restoration projects. Based on this, we intend to present improvement measures for Sea Area Utilization Consultations and Impact Assessments for restoration projects. This will provide effective information for future policies and plans.

Ecological Monitoring on Changes in Microclimate, Vegetation and Soil Properties after 2 Years in Restoration Project Sites Linking the Ridgeline of Baekdudaegan (백두대간 생태축 복원사업 2년 후 산림미기상, 식생 및 토양특성 변화 모니터링)

  • The Korea Forest Service(KFS) has been initiating restoration activities of ridgeline in damaged and fragmented areas of Baekdudaegan since 2011. Completed project in Ihwaryeong, Yuksimnyeong & Beoljae(2012; 2013) were selected as sites for this study. The changes in microclimate condition, vegetation composition and soil properties between project sites and adjacent stands were compared to evaluate the effect of restoration at early stage(after 2years). Pinus densiflora was planted mainly for these restoration sites, however Robinia pseudoacacia and Alnus sibirica invaded the area two years after the restoration activities. Ihwaryeong showed the most changes in understory vegetation among the study sites. Exotic species, such as Ambrosia artemisiifolia, Oenothera odorata, Erigeron annuus, and Coreopsis tinctoria invaded Ihwaryeong, and the dominance have invaded currently. It resulted from the poor survival rate of trees and high difference in microclimate wherein there's an increased temperature and decreased humidity in both restored sites and adjacent stands. In addition, it is also caused by poor soil chemical property, especially pH and organic matter content due to lack of humus layer and its accumulation, compared to adjacent forest soil in restored sites. Significant difference on chemical soil property was observed between restored sites and adjacent forest but no significant difference was observed after two years of restoration. Ecological monitoring is needed to understand the ecological changes after restoration and to establish a long-term management strategy.
