“…The slope of the linear relationship could be considered the sequestration rate. Our results (Table 3) were numerically smaller than previously published data on WRP in North America (Euliss et al, 2006) and on restored wetlands but non‐WRP lands in the Platte River valley of central Nebraska (Meyer et al, 2008). This is likely because our study area was located in southern North America, where soil temperatures are much higher.…”

Wetlands have many valued ecological functions, yet the impact of the Wetlands Reserve Program (WRP) on soil change, such as carbon dynamics, still remains controversial. Soils from four WRP age classes (8, 12, 15, and 18 yr) and adjacent croplands in St. Landry Parish, Louisiana, USA were sampled by fixed depth (0–10, 10–20, 20–30, and 30–40 cm). Soil physiochemical properties such as bulk density (Db), pH, soil organic matter (SOM), total carbon (TC), total nitrogen (TN), and sand, silt, and clay content were analyzed. Results showed that returning cropland to wetland significantly increased porosity and lowered soil pH. Slight changes in soil texture from silty clay to clay were also noted, but may be a feature of soil spatial variability rather than differences imposed by land use. Linear relationships existed between 0 and 40 cm for content of SOM, TC, or TN and WRP age (P < 0.05), illustrating WRP could benefit carbon and nitrogen sequestration. Sequestration rates of SOM, TC, and TN were 0.305, 0.095, and 0.004 kg m−2 yr−1, respectively. Significant correlation relationships existed among most of these soil properties, suggesting human activities such as wetland restoration may trigger co‐dynamics of properties in the soil system. These findings highlight the potential of WRP in climate change mitigation, and give some suggestions for better soil management in this restoration program.

“…Such disturbances can undermine a wetland's ability to capture carbon, but critically, result in microbial breakdown, demineralization and ultimately release of significant amounts of carbon that had already been stored (Atwood et al., ; Lal et al, ; Page & Dalal, ; Pendleton et al., ). Conversion to agricultural land for cropping and grazing can lead to 80%–96% reduction in wetland soil organic carbon (Meyer, Baer, & Whiles, ; Sigua, Coleman, & Albano, ). By providing estimates on wetland carbon stocks, and wetland loss, we can use this information to estimate the carbon losses from wetland degradation.…”

Nontidal wetlands are estimated to contribute significantly to the soil carbon pool across the globe. However, our understanding of the occurrence and variability of carbon storage between wetland types and across regions represents a major impediment to the ability of nations to include wetlands in greenhouse gas inventories and carbon offset initiatives. We performed a large‐scale survey of nontidal wetland soil carbon stocks and accretion rates from the state of Victoria in south‐eastern Australia—a region spanning 237,000 km2 and containing >35,000 temperate, alpine, and semi‐arid wetlands. From an analysis of >1,600 samples across 103 wetlands, we found that alpine wetlands had the highest carbon stocks (290 ± 180 Mg Corg ha−1), while permanent open freshwater wetlands and saline wetlands had the lowest carbon stocks (110 ± 120 and 60 ± 50 Mg Corg ha−1, respectively). Permanent open freshwater sites sequestered on average three times more carbon per year over the last century than shallow freshwater marshes (2.50 ± 0.44 and 0.79 ± 0.45 Mg Corg ha−1 year−1, respectively). Using this data, we estimate that wetlands in Victoria have a soil carbon stock in the upper 1 m of 68 million tons of Corg, with an annual soil carbon sequestration rate of 3 million tons of CO2 eq. year−1—equivalent to the annual emissions of about 3% of the state's population. Since European settlement (~1834), drainage and loss of 260,530 ha of wetlands may have released between 20 and 75 million tons CO2 equivalents (based on 27%–90% of soil carbon converted to CO2). Overall, we show that despite substantial spatial variability within wetland types, some wetland types differ in their carbon stocks and sequestration rates. The duration of water inundation, plant community composition, and allochthonous carbon inputs likely play an important role in influencing variation in carbon storage.

“…In each plot, three 10×10 m soil sampling quadrates were randomly chosen. Within a sampling quadrate, five 0 to 10 cm depth soil cores were extracted using a 3.6-cm diameter auger and were composite into one sample as the surface soils experienced the most changes during the reforestation process (Meyer et al 2008). The soil core was extracted at a distance of 50 cm from trunk of the dominant tree in the quadrate as microbial community might vary with distance to trunk (Saetre and Bååth 2008).…”

Carbon metabolism of soil microbial communities of restored forests in Southern China

Purpose The structure and dynamics of carbon metabolic process of the soil microbial community in restored forests were dependent on the methods employed in reforestation and subsequent management. To find an appropriate method to restore degraded forests and to assess the ecological benefits of restorations, we studied community level physiological profiles of soil microbial communities in forests in Southern China that were restored by three different methods. Materials and methods Community level physiological profiles of soil microbial communities in restored introduced slash pine (Pinus elliottii) plantation, restored native Masson pine (Pinus massoniana) plantation, and natural secondary forest in Southern China were studied based on outcomes of the Biolog TM Ecoplates incubation. For each type of restored forest, 15 experimental plots were randomly selected in Southern China. In each plot, three composite samples of 0 to 10 cm depth were obtained from three subplots for the analyses. Results and discussion It was found that the soil microbial communities of three types of restored forests were capable of metabolizing all 31 preselected carbon substrates on Biolog TM Ecoplates. However, the soil microbial community of the natural secondary forest was more diverse in structure of carbon metabolism, and more efficient in utilizing the carbon substrates than those of the Masson pine and slash pine plantations that had to acclimate and adopt different biochemical pathways to metabolize some of the carbon substrates. Soil available N content, moisture content, organic C content, microbial biomass C content, pH, clay content, and Shannon-Wiener diversity index of tree layer were factors contributing to the carbon source utilization structure of the soil microbial communities for the three types of restored forests. Conclusions The soil microbial communities of all three types of restored forests would provide the same ecological services in metabolizing carbon sources in the forest soils. The microbial community of the natural secondary forest was consistently more efficient in carbon utilization than those of the Masson pine and slash pine plantation and often the Masson pine plantations were more efficient than that of the slash pine plantations. The natural secondary forest had a more diverse and stable soil microbial ecosystem and would be more adaptable to and respond more rapidly to environmental changes.
