  • Suncheonman-Bay and its surrounding areas play important roles as habitats for migratory birds. However, sustainable management of these areas is difficult because of the development pressure of private lands. Therefore, the areas surrounding Suncheonman-Bay must be classified as additional protected areas; for this, it is necessary to gather concrete and objective evidence and ensure protected area management. Further, compensation measures must be considered when acquiring a private property as an additional protected area. In this study, we distinguish protected areas, such as core, buffer, and transition areas, within a private area by using data from the Winter Waterbird Census of Korea and MARXAN software, a spatial conservation prioritization tool. We applied ecosystem services to apply Payment for Ecosystem services (PES) as compensation measures. Watershed conservation (supply), climate control (regulation), supporting habitats (support), and recreation (culture) etc. were evaluated by calculating the economic value of these ecosystem services. Eastern, western, and northern forests and rice fields of Suncheonman-Bay were shown to have a number of core areas for the preservation of endangered species. The ecosystem service value of the additional protected areas was estimated at 17.5 million KRW/ha/year. We believe that our study result could be used to establish protected areas to preserve major habitats, as well as include areas adjacent to such major habitats that play a vital role in endangered species conservation. In addition, through this study, we highlight the need for an objective basis to establish protected areas.

  • This study analyzed the relationship between environmental factors and the temporal changes of the bird populations during the every January from 1999 to 2016 (18 years) in Donglim reservoir. 'Winter Waterbird Census of Korea' data by National Institute of Biological Resources were used for the bird population data, and principal component analysis and cluster analysis were used to analyze the changes of annual population. The average temperature of January and the average storage rate of the reservoir were used as environmental factors. According to the results of the study, the population changes in the study area can be explained by the increase and decrease of two water bird groups and a mountain bird group. The average temperature of the years when the population of water bird groups increased was more than $1.4^{\circ}C$ in comparison with the year when mountain birds increased. On the other hand, the influence of the water content was not clear. The visiting of Baikal Teal affected by temperature was a factor affecting the other group of water bird and a mountain bird group. The results of this study suggest that the temperature change affects the global spatial distribution of birds and the migration of large population species such as Baikal Teal affects species composition and populations of birds at local scale. Therefore, understanding of environmental changes at large scale and spatial distribution of species and flock contributes to understand the temporal variation of the bird population at regional or local scales.
