In this study, we analyzed the characteristics of microclimate in three types of coniferous forest stand in mountainous areas of Korea, categorized as Pinus densiflora Siebold & Zucc. (PD), Pinus koraiensis Siebold & Zucc. (PK), and Larix kaempferi (Lamb.) Carrière (LK). Climate data were obtained using a HOBO data logger installed in each forest stand, and meteorological factors were compared between forest land and nonforest land (weather stations) from July 2015 to May 2017. The differences in daily mean temperature, daily mean maximum temperature, daily mean minimum temperature, and daily mean relative humidity between three study sites and weather stations were significant, except for the daily mean temperature difference at the PD site. The meteorological differences between forest areas and weather stations reflect different forest characteristics such as forest type and tree density. The results also indicate that, even if the same tree species is planted in a forest area, the effects of the microclimate can vary depending on the environmental characteristics of the forest stand such as elevation, slope, and latitude.
