North American prairie wetlands are important non-forested land-based carbon storage sites.

چکیده
We evaluated the potential of prairie wetlands in North America as carbon sinks. Agricultural conversion has resulted in the average loss of 10.1 Mg ha(-1) of soil organic carbon on over 16 million ha of wetlands in this region. Wetland restoration has potential to sequester 378 Tg of organic carbon over a 10-year period. Wetlands can sequester over twice the organic carbon as no-till cropland on only about 17% of the total land area in the region. We estimate that wetland restoration has potential to offset 2.4% of the annual fossil CO(2) emission reported for North America in 1990.

A comparison of carbon and nitrogen stocks among land uses/covers in coastal Florida R. Chelsea Nagy, B. Graeme Lockaby,
Coastal areas are rapidly developing due to population growth and the appeal of coastlines. In order to gain insight into how land use/cover affects carbon (C) storage in a coastal context, we examined soil and vegetation C and soil nitrogen (N) across land uses near Apalachicola, FL. Forested wetlands had the greatest soil C and N storage, while natural pine forests and pine plantations had th...
متن کاملGreenhouse gas fluxes in southeastern U.S. coastal plain wetlands under contrasting land uses.
Whether through sea level rise or wetland restoration, agricultural soils in coastal areas will be inundated at increasing rates, renewing connections to sensitive surface waters and raising critical questions about environmental trade-offs. Wetland restoration is often implemented in agricultural catchments to improve water quality through nutrient removal. Yet flooding of soils can also incre...
متن کاملHistorical Trends in Rusty Blackbird Nonbreeding Habitat in Forested Wetlands
Rusty Blackbird (Euphagus carolinus) populations have declined perhaps 95% in the recent past, creating legitimate concern that the species may become endangered. During the nonbreeding period the species occurs predominantly in southern U.S. forested wetland habitats, with concentrations in the Mississippi Alluvial Valley and in the southeastern Coastal Plain of the Carolinas and Georgia. Both...
متن کاملTropical wetlands: A missing link in the global carbon cycle?
Tropical wetlands are not included in Earth system models, despite being an important source of methane (CH4) and contributing a large fraction of carbon dioxide (CO2) emissions from land use, land use change, and forestry in the tropics. This review identifies a remarkable lack of data on the carbon balance and gas fluxes from undisturbed tropical wetlands, which limits the ability of global c...
متن کاملInland wetlands mapping and vulnerability assessment using an integrated geographic information system and remote sensing techniques
The understanding of inland wetlands’ distribution and their level of vulnerability is important to enhance management and conservation efforts. The aim of the study was to map inland wetlands and assess their distribution pattern and vulnerability to natural and human disturbances such as climate change (temperature increase) and human activities by the year 2080. Inland wetland types i.e. for...
