“…In this study, a positive correlation was found between the density and mortality rate of the Korean fir. This is consistent with Kim et al [23], who reported changes in the distribution of the Korean fir on Mt. Halla between 2006 and 2015.…”

“…Previous studies have employed a variety of methods to investigate the distribution of the Korean fir, e.g., by utilizing aerial photographs or satellite images to map the stands of Korean fir [20][21][22], or calculating the areas above a certain crown density [23,24] (Table 10). In this study, it was possible to identify that the individual Korean firs and an area of 928.8 ha consisting of 60 × 60 m square grid cells, each containing at least 36 individual live trees, was identified as the distribution area of Korean fir.…”

“…Methods used in previous studies involved identifying the boundaries of the Korean fir stands and calculating the total area of these stands [20,21]. Several factors may affect the calculation of the distribution area, e.g., excluding an area in which small stands or individual trees were sporadically distributed from the distribution area, or, including an area in which no Korean firs were distributed in a large-scale stand [23]. In contrast, calculating the distribution area based on crown density (>10%) (e.g., References [23,24]) is considered a more objective method.…”

“…Given that the mortality and density of the Korean fir on Mt. Halla varies depending on the aspect of the land on which the trees are growing, as reported in previous studies [9,21,23,25], a comprehensive analysis of the entirety of the Mt. Halla region is warranted, so as to identify the overall distribution of the Korean fir on the mountain.…”

“…Previous studies dealing with the spatial distribution of the Korean fir have been conducted selectively in specific study areas with high-density, extensive, pure stands of Korean fir [17][18][19]. As a complement to this, recent studies have utilized aerial photographs or satellite images to examine the changing patterns in the distribution of the Korean fir [20][21][22][23][24].…”

Research Highlights: Technology advances have allowed for a new approach to research the decline of the Korean fir (Abies koreana E.H.Wilson). This study provides insights into the exact causes leading to this decline. Background and Objectives: Various factors could lead to the decline of fir trees around Mt. Halla, Korea, but these have not yet been verified. Here, the Korean fir across Mt. Halla were classified as dead or living and mapped using high-resolution orthorectified aerial images and three-dimensional (3D) stereoplotting. Materials and Methods: Aerial photographs were used to map spatial distribution and analyze the distribution patterns and mortality of the Korean fir. The electronic stereoplotting program (Geo3Di-PRO) enabled the creation of 3D images from aerial photographs. General, altitudinal, and topographical distribution was assessed. Results: Their accumulated percent mortality rate (APMR) showed positive correlations with altitude and tree density, a negative correlation with terrain slope, and no consistent correlation with solar radiation. The results indicate that increases in the density of Korean firs are related to decreased growth in areas at high altitude, on gentle slopes, and with high solar radiation. Consistent positive correlations between density and APMR indicate that fir mortality can be attributed to environmental deterioration and the establishment of unfavorable growth conditions. Areas with high APMR and density had gentle slopes, thus high soil moisture, or relatively high annual precipitation owing to high altitude. Conclusion: Fir mortality on Mt. Halla can be attributed to long-term persistently high rainfall and subsequent excess soil moisture.

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 .
