Quantification of carbon stock to understand two different forest management regimes in Kayar Khola watershed, Chitwan, Nepal

A Basin-Scale Estimation of Carbon Stocks of a Forest Ecosystem Characterized by Spatial Distribution and Contributive Features in the Liuxihe River Basin of Pearl River Delta

“…We randomly sampled three soil profiles in each 30 m × 30 m plot. The soil layers were grouped into six depth intervals: 5 (0-10), 15 (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20), 25 (20-30), 40 (30-50), 60 , and 85 (70-100) cm. First, each layer of the soil samples was sealed in plastic bags, brought back to the laboratory, air-dried, and sieved through a 0.15 mm mesh before performing the chemical analyses.…”

“…The soil samples for SOC contents (%) determination were taken from the soil profile at six depth levels: 5 (0-10), 15 (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20), 25 (20-30), 40 (30-50), 60 , and 85 (70-100) cm. The SBF had the highest SOC content (3.37%) at 5 cm depth out of all measured forest types (Figure 5a).…”

“…The results of this study, which provide baseline forest C stock data for ecosystem services and regional C flux research, are useful to support the basin-scale forest management and land use change. economic value, planted forests play an important role in C sequestration, both at a regional and global scale [16,17].Forest ecosystems store large amounts of biomass C and soil C, and many recent studies of C stocks have examined the climax communities of forests while the consideration of understory vegetation has been commonly neglected [18][19][20]. The composition of tree species must affect the forest canopy and the understory vegetation, and it could continue to affect soil properties [21,22].…”
