한국 산양(Naemorhedus caudatus)의 서식지적합성 평가 및 카메라트래핑 검증에 관한 연구 = HSI-based Habitat Suitability Assessment and Validation Using Camera Traps for the Long-tailed Goral (Naemorhedus caudatus) in Korea

다국어 초록 (Multilingual Abstract)

This study quantitatively evaluated the Habitat Suitability Index (HSI) of Goral(Naemorhedus caudatus), a class I endangered wild life, in the Hongcheon-gun area of Gangwon State, and verified the predictive ability of the model through an Camera Trapping. 8 habitat variables were selected, including altitude, slope, slope, slope, cliff and rock formation, water system distance, vegetation type, road distance, and artificial interference distance, and the Suitability Index (SI) of each variable was standardized to 0 1 by reflecting previous studies and field ecological knowledge. The input data was pretreated with a resolution of 30 m and then counted as a 100 × 100 m evaluation grid (Total 1,200) and spatial analysis using ArcGIS 10.8 was performed. As a result of the analysis, the most fitted section of the study area was 27.4 % and the fitted section was 43.3 %, and about 70.7 % of the total was evaluated as an area suitable for Goral habitats. However, because covering resources such as cliffs and rock formation were unevenly distributed, the habitat tended to be concentrated in some core patches. As a result of verifying the Trail Camera, the Goral was confirmed at 22 (41.5%) out of the total 53 installation points, and 88% of the appearances were recorded in the above-fit section of the HSI, showing a high degree of agreement with the actual distribution. Seasonal appearances were concentrated in spring, summer, and autumn (March November), suggesting the possibility that this area may perform the function of a moving corridor between nearby populations. In terms of conservation, areas where cover resources are concentrated, such as cliffs and steep valleys, are core habitats and need to be protected first, and coniferous right-handed forests should expand food resources through the conversion of mixed filial piety forests and the restoration of lower vegetation. In addition, it is required to secure a 300 600 m buffer zone and create ecological passages around roads and buildings. In conclusion, the HSI model of this study presented a scientific basis that can be used for future habitat restoration, ecological axis connection, and data-based species conservation policies by quantitatively explaining the spatial quality and distribution of mountain goat habitats and verifying them with field data.
