Wild bees are considered main pollinators, but their diversity is rapidly declining worldwide. Consequently, there is a need to create and manage open habitats preferred by wild bees. However, in Korea, it is difficult to provide suitable habitats as approximately 63% of the land is covered by forests. This study was conducted to investigate the distribution of wild bees in open habitats within forests in which natural grasslands and artificially created clearcut areas were compared. In the spring of 2024, from April to May, wild bees were sampled for two weeks using pan traps in the academic forest of Kangwon National University, located in Chuncheon. Two types of habitats were selected: one was a natural grassland with minimal human disturbance, and the other was a clearcut area that was harvested in 2022 and has since developed into an open habitat. A total of 39 species with 4,183 individuals in the grassland and 51 species with 1,453 individuals in the clearcut area were collected and identified. The number of individuals was significantly higher in the grassland compared to the clearcut area, but there was no difference in species richness. Individual-based rarefaction curves predicted a higher number of species in the clearcut area for the same number of individuals. Non-metric multidimensional scaling and analysis of similarities showed that the species composition was significantly different between the grassland and clearcut area. This suggests that grasslands function as stable habitats, while clearcut areas serve as habitats where various species are being introduced due to forestry.
