생활권 멧돼지 분포 및 서식 특성 연구

Abstract

The social and economic problems caused by wild boars are caused by various and complex factors such as habitat fragmentation and habitat reduction due to rapid industrialization and urbanization, imbalance of forest ecosystems due to the absence of top predators in the habitat, lack of coordination ability, and vigorous fertility. do. This study aims at Seosan-si, Chungcheongnam-do, where the damage of wild boars is increasing rapidly and rescue activities such as capture groups are actively and systematically conducted. It was carried out to build the DB and derive the possible distribution. did. The GIS DB of the affected area was established and the basic status analysis was performed for selection of possible habitat distribution sites. Habitat environment analysis uses a numerical topographic map (1:5,000) and QGIS to analyze the land cover status, forest location map, and analyze and superimpose habitat distribution in agricultural areas and grasslands near forests. possible was written. The damage to wild boars in Seosan-si has increased rapidly in the last 4∼5 years and is gradually spreading to other towns and villages and other cities and counties in the city. Existing catching activities in Seosan City average 150∼200 individuals per year. The birth rate of wild boars is about 6∼7, of which 4∼5 survive. The radius of activity is around 10km from the habitat, and the proper management density is 5∼6 individuals per km2. Continuous catching activities of 100∼150 or more individuals are required.
