“…This is consistent with previous findings for spruce and pine forests, with global forest data (Paré and Cleve, 1993;Zhou and Dean, 2004;Ordoñez et al, 2009). In other studies, soil, climate, landscape, and space together explained 61% of the variation in above-ground biomass in rain forest and 69.2% in spruce forest (Cao et al, 2019;Santiago-García et al, 2019). Our results also indicated that above-ground species of tree is important for above-ground and soil organic C stocks, explaining 30% and 10% of variation, respectively.…”

Plant-soil interactions are a major determinant of changes in forest ecosystem processes and functioning. We conducted a trait-based study to quantify the contribution of plant traits and soil properties to above-and below-ground ecosystem properties in temperate forest in the Indian Himalayas. Nine plant traits (leaf area, specific leaf area, leaf water content, leaf dry matter content, leaf carbon (C), nitrogen (N), phosphorus (P), leaf C/N, and leaf N/P) and eight soil properties (pH, moisture, available N, P, potassium (K), total C, N, P) were selected for determination of their contribution to major ecosystem processes (above-ground biomass C, soil organic C, soil microbial biomass C, N, and P, and soil respiration) in temperate forest. Among the plant traits studied, leaf C, N, P, and leaf N/P ratio proved to be the main contributors to above-ground biomass, explaining 20-27% of variation. Leaf N, P, and leaf N/P were the main contributors to below-ground soil organic C, soil microbial biomass C, N, and P, and soil respiration (explaining 33% of variation). Together, the soil properties pH, available P, total N and C explained 60% of variation in above-ground biomass, while pH and total C explained 56% of variation in soil organic C. Other soil properties (available P, total C and N) also explained much of the variation in soil microbial biomass C (52%) and N (67%), while soil pH explained some of variation in soil microbial biomass N (14%). Available P, total N, and pH explained soil microbial biomass P (81%), while soil respiration was only explained by soil total C (70%). Thus leaf traits and soil characteristics make a significant contribution to explaining variations in above-and below-ground ecosystem processes and functioning in temperate forest in the Indian Himalayas. Consequently, tree species for afforestation, restoration, and commercial forestry should be carefully selected, as they can influence the climate change mitigation potential of forest in terms of C stocks in biomass and soils.

Variations in plant functional traits might reveal the adaptation strategies of vegetation under changing environment. However, few studies have focused on the variation of dominant plant functional traits in changing soil water content in marsh wetland of the arid regions. In this study, functional traits were investigated in the dominant species Phragmites australis growing at distinct soil water contents in marshes of the arid middle-lower reaches of the Shule River Basin in Northwest China. Three soil water gradients (33.38 ± 1.40, 15.97 ± 1.99 and 10.22 ± 1.61%) were identified from three marsh sites. Results showed that leaf thickness, specific leaf area, maximum height and leaf phosphorous content in P. australis were significantly varied from the high soil water to low soil water in arid marshes. Soil water content driven variations in functional traits of P. australis, mainly by its effect on soil salinity and available nitrogen, affected the functional traits of P. australis. In conclusion, in marshes of arid regions, P. australis adapted well to resource-poor habitats through the coordinated combination of multiple functional traits i.e., low specific leaf area, leaf nitrogen content and leaf phosphorous content, high leaf dry matter content and leaf thickness, which reflected that P. australis had conservative strategy. © 2021 Friends Science Publishers

“…Vegetation patches can reduce the removal of litter, and the resulting accumulation of litter results in a concurrent accumulation of soil organic carbon (21). Nevertheless, the rapid growth of vegetation may lead to the depletion of soil nutrients through the action of soil microorganisms and root uptake, resulting in the deterioration of soil quality, or even the conversion of carbon sinks into carbon sources (22). Cao et al (22) found that the amount of litter decreases with stand age, thus reducing the amount of nutrients released into the soil.…”

Cao et al (22) found that the amount of litter decreases with stand age, thus reducing the amount of nutrients released into the soil. Therefore, an accurate and reliable assessment of soil carbon storage during the later stage of vegetation restoration is required to facilitate rational planning of future plantation management (23).…”

Emerging consensus is that land-use change resulting through the “Grain for Green” project has had a significant impacted on soil organic carbon (SOC), thereby probably enhancing the carbon sequestration capacity of terrestrial ecosystems. However, it remains largely unknown whether a watershed acts as a source or sink of soil carbon during the later period of ecological restoration. This study comprehensively investigated the changes of SOC stock in 2005, 2010, and 2017 along different land-use types. It was aimed to evaluate the dynamics to SOC storage capacity over different vegetation restoration maturity in the Shanghuang Watershed, China. The results showed that restoration increased the accumulation of organic carbon pools in the early stage. Significant increases in SOC stock were observed in shrubland and grassland in comparison to that in other land uses, and these two land-use types represented the optimal combination for ecological restoration in the basin. The SOC stock did not increase indefinitely during the long-term vegetation restoration process, but rather first increased rapidly with vegetation planting and reached a peak, following which it declined slightly. Therefore, pure vegetation restoration cannot maintain a permanent soil carbon sink, some measures to maintain the stability of carbon and to prolong soil C persistence are essential to take.
