“…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.…”

“…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.

“…Although the subalpine zone at Mt. Halla offers optimal conditions for conducting long-term ecological research to investigate effects of climate change on ecosystems (Song 2011), the Abies koreana forest is endemic to Korea, and a rare one; as such, studies on C budget are lacking.…”

Background: The Northern Hemisphere forest ecosystem is a major sink for atmospheric carbon dioxide, and the subalpine zone stores large amounts of carbon; however, their magnitude and distribution of stored carbon are still unclear. Results: To clarify the carbon distribution and carbon budget in the subalpine zone at volcanic Jeju Island, Korea, we report the C stock and changes therein owing to vegetation form, litter production, forest floor, and soil, and soil respiration between 2014 and 2016, for three subalpine forest ecosystems, namely, Abies koreana forest, Taxus cuspidata forest, and Juniperus chinensis var. sargentii forest. Organic carbon distribution of vegetation and NPP were bigger in the A. koreana forest than in the other two forests. However, the amount of soil organic carbon distribution was the highest in the J. chinensis var. sargentii forest. Compared to the amount of organic carbon distribution (AOCD) of aboveground vegetation (57.15 t C ha −1) on the subalpine-alpine forest in India, AOCD of vegetation in the subalpine forest in Mt. Halla was below 50%, but AOCD of soil in Mt. Halla was higher. We also compared our results of organic carbon budget in subalpine forest at volcanic island with data synthesized from subalpine forests in various countries. Conclusions: The subalpine forest is a carbon reservoir that stores a large amount of organic carbon in the forest soils and is expected to provide a high level of ecosystem services.

Background: In order to investigate organic carbon distribution, carbon budget, and cycling of the subalpine forest, we studied biomass, organic carbon distribution, litter production, forest floor litter, accumulated soil organic carbon, and soil respiration in Taxus cuspidata forest in Halla National Park from February 2012 to November 2013. Biomass was calculated by using allometric equation and the value was converted to CO 2 stocks. Results: The amount of plant organic carbon was 13.60 ton C ha
