Succession is defined as variation in ecological communities caused by environmental changes. Environmental succession can be caused by rapid environmental changes, but in many cases, it is slowly caused by climate change or constant low-intensity disturbances. Odaesan National Park is a well-preserved forest located in the Taebaek mountain range in South Korea. The forest in this national park is progressing from a mixed-wood forest to a broad-leaved forest. In this study, microbial community composition was investigated using 454 sequencing of soil samples collected from 13 different locations in Odaesan National Park. We assessed whether microbial communities are affected by changes in environmental factors such as water content (WC), nutrient availability (total carbon (TC) and total nitrogen (TN) and pH caused by forest succession. WC, TC, TN and pH significantly differed between the successional stages of the forest. The WC, TC and TN of the forest soils tended to increase as succession progressed, while pH tended to decrease. In both successional stages, the bacterial genus Pseudolabrys was the most abundant, followed by Afipia and Bradyrhizobium. In addition, the fungal genus Saitozyma showed the highest abundance in the forest soils. Microbial community composition changed according to forest successional stage and soil properties (WC, TC, TN, and pH). Furthermore, network analysis of both bacterial and fungal taxa revealed strong relationships of the microbial community depending on the soil properties affected by forest succession.
