“…SOC values for Chillimo and Jibat are comparable with the results reported for Gedo forests (Yohannes et al 2015;Birhane et al 2017). The result obtained from Chillimo forest fragments is comparatively similar to what has been reported (Demessie et al 2013;Tesfaye et al 2016;Han et al 2018).…”

Background: Deforestation and degradation are currently affecting the ecosystem services of forests. Among the ecosystem services affected by deforestation and degradation are the amount of soil organic carbon (SOC) and total nitrogen (TN) stored in forest soils which have greater impacts in global climate change. This study aimed at examining the amount of SOC and TN in the forest fragments which were separated from the continuous tracts of forests of Jibat and Chillimo through fragmentation processes over four decades. Methods: We have sampled soils from 15 forest fragments of Chillimo and Jibat in the central highlands of Ethiopia. The soil samples obtained in two separate soil depths (0-30 and 30-60 cm) were bulked, dried, and sieved for analysis. Results: Our results have shown that the two sites (Jibat and Chillimo forest fragments) differed in their SOC and TN contents. While the values for Jibat were found to be 29.89 Mg/ha of SOC and 2.84 Mg/ha for TN, it was 14. 06 Mg/ha of SOC and 1.40 Mg/ha for TN for Chillimo. When all forest fragment soil samples were bulked together, Jibat site had twice the value of SOC and TN than Chillimo. When disaggregated on the basis of each fragments, there existed differences in SOC (1.86 Mg/ha and 42.15 Mg/ha) and TN (0.24 Mg/ha and 4.23 Mg/ha) values. Among the forest fragments, fragment four (F 4) had the highest Relative Soil Improvement Index (RSII) value of 3826.82% and fragment fifteen (F 15) had the lowest RSII value (726.87%) which indicated that the former had a better quality of soil properties than the latter. Conclusion: SOC and TN differed across sampled fragments and sites. Variations in soil properties are the reflections of inherent soil parent material, aboveground vegetation, human interferences, and other physical factors. Such differences could be very important for identifying intervention measures for restoration and enhancing ecosystem services of those fragments.

“…However, high P stocks in basalt could be due to P inputs through leaf litterfall from high P concentrations in >1-year-old leaves in the basalt parent material. The C stocks of the forest floor in this study were within 3610-6390 kg C ha À1 of the Q. glauca stands on basalt reported by Han et al (2018).…”

“…The mean values of the aboveground C stocks were 110,027 kg C ha À1 for basalt and 73,071 kg C ha À1 for sandstone. Aboveground C stocks in basalt were slightly lower than the reported range (124,500-132,630 kg C ha À1 ) for Q. glauca stands in basalt in Jeju-do, Korea (Han et al 2018), whereas the values in sandstone were considerably lower than the range. However, the mean values (basalt: 958 kg N ha À1 , sandstone: 491 kg N ha À1 ) of the N stocks of the tree components were considerably higher than 226 kg N ha À1 for other coniferous forests in Korea (Kim 1999).…”

“…The Japanese blue oak (Quercus glauca Thunb.) is distributed in a broad range of sites in the subtropical forests of Korea (Han et al 2018;. Thus, this tree species was used to determine whether parent materials originating from different rock types could explain variations in the nutrient stocks of tree biomass, forest floor, and mineral soils.…”

Soil parent materials originating from different geologic settings represented broad differences in the forest nutrient environment, but few studies have been conducted on the relationships between soil parent materials and nutrient stocks in forest stands. This study was performed to compare the nutrient stocks of Japanese blue oak (Quercus glauca Thunb.) stands grown on forest soils inherited from two different parent materials, basalt and sandstone, in southern Korea. A total of 29 Japanese blue oak trees were destructively sampled (15 trees on basalt and 14 trees on sandstone) to compare the nutrient content of the tree components (stem wood, stem bark, branches, and leaves). Samples of the forest floor and a soil depth of 0-30 cm were collected to measure the nutrient stocks of the two parent materials. The mean nutrient concentrations of the tree components varied significantly between the basalt and sandstone parent materials. The mean carbon and potassium concentrations of stem wood were significantly higher in sandstone than in basalt, whereas the nitrogen concentration of stem wood and stem bark were lower in sandstone than in basalt (p < .05). A significantly higher carbon, nitrogen, potassium, and magnesium stocks of the forest floor were found in sandstone than in basalt. However, the soil carbon, nitrogen, calcium, and magnesium stocks at a depth of 0-30 cm were significantly higher in basalt than in sandstone. The results demonstrate that the aboveground nutrient concentration and belowground nutrient stocks of Japanese blue oak stands can be altered greatly by different parent materials.

“…In order to evaluate the ecological value of carbon cycle in Korea, researches have been done on natural forests, such as Quercus mongolica forest and Pinus densiflora forest in Mt. Worak, Quercus glauca forest, and Taxus cuspidata forest in Jeju Island (Won et al 2015;Jang et al 2017;Han et al 2018), and they did not attempt to evaluate the ecological value of the carbon cycle for urban forests.…”

Background: Standing biomass, litter production, rate of litter decomposition, amount of litter on forest floor, and amount of soil organic carbon distribution were investigated from March 2016 to November 2018 in order to evaluate the ecosystem value through organic carbon distribution in the Pinus densiflora forest at Namsan, Seoul Metropolitan City. Results: The amount of organic carbon in the Pinus densiflora forest was 261.09 ton C ha −1 during the research period, and fixed organic carbon in plant through net photosynthesis was 3.2 ton C ha −1 year −1. The organic carbon in plant was 62.77 ton C ha −1 (24.04%), in litter on the forest floor was 3.65 ton C ha −1 (1.40%), and in soil was 194.67 ton C ha −1 (74.56%). The value of plant, litter on forest floor, and soil organic carbon distribution were each 6,277,000 won ha −1 , 365, 000 won ha −1 , and 19,467,000 won ha −1. The value per ton of fixed organic carbon in plant through net photosynthesis was 320,000 won ha −1 year −1 and the value of ecosystem services stored in carbon in the Namsan forest ecosystem was about 26.1 million won ha −1 for 3 years. Conclusions: The results of this study suggest that the pine forests of Namsan rapidly decompose leaves due to the high atmospheric temperature and accumulate a large amount of organic carbon in the soil to provide climate control regulatory service function.
