“…Halla. The high OM contents may be attributed to the low annual temperatures and large numbers of annual cloudy days in the natural habitats of A. koreana due to high altitudes [ 55 ] as temperature and moisture strongly affect microbial biomass and soil OM mineralization [ 56 , 57 ]. The OM contents in Mt.…”

“…The quantity and quality of soil OM are very closely linked to soil nitrogen [ 62–64 ]. Since OM is one of the primary sources of forest soil TN [ 65 ], areas with high OM contents have been found to have relatively high TN [ 18 , 55 ]. Furthermore, higher TN contents ranging from 0.38% to 1.50% were recorded in all our study sites and these values were higher than the average TN content (0.19%) of typical Korean forest soils [ 53 ].…”

A rapid decline of Abies koreana has been reported in most of the natural alpine habitats in Korea. It is generally accepted that this phenomenon is due to climate change even though no clear conclusions have been drawn. Most research has focused on abiotic environmental factors, but studies on the relationships between A. koreana and soil fungal microbiomes are scarce. In this study, the rhizoplane and rhizosphere fungal communities in the alive and dead Korean fir trees from its three major natural habitats including Mt. Deogyu, Mt. Halla, and Mt. Jiri in Korea were investigated to identify specific soil fungal groups closely associated with A. koreana . Soil fungal diversity in each study site was significantly different from another based on the beta diversity calculations. Heat tree analysis at the genus level showed that Clavulina , Beauveria , and Tomentella were most abundant in the healthy trees probably by forming ectomycorrhizae with Korean fir growth and controlling pests and diseases. However, Calocera , Dacrymyces , Gyoerffyella , Hydnotrya , Microdochium , Hyaloscypha , Mycosymbioces , and Podospora were abundant in the dead trees. Our findings suggested that Clavulina , Beauveria , and Tomentella are the major players that could be considered in future reforestation programs to establish ectomycorrhizal networks and promote growth. These genera may have played a significant role in the survival and growth of A. koreana in its natural habitats. In particular, the genus Gyoerffyella may account for the death of the seedlings. Our work presented exploratory research on the specific fungal taxa associated with the status of A. koreana .
