Reported rates of soil organic carbon (SOC) accumulation in wetlands are markedly higher over recent versus longer timescales, caused by SOC losses through decomposition, paleoenvironmental changes, and increases sedimentation or biomass production. Explaining changes sequestration determining the time horizon which high sustained both critical for accurately measuring potential wetland conservation as a natural climate solution. Here, we present analyses on 4-m core from riverine-influenced...
Dinerstein et al. present a spatially explicit global framework for protected areas needed to reverse catastrophic biodiversity losses and stabilize climate. The Province of Ontario (Canada) stands out in this “Global Safety Net (GSN)” as critical jurisdiction meeting those goals, because both the large extent roadless lands high carbon storage terrestrial ecosystems. Simultaneously, pressure is increasing develop unmanaged Ontario, particularly Far North, resource extraction. Here, we...
Freshwater marshes are prevalent and important stores of carbon. They bury carbon in deeper soils, although reported rates accumulation significantly higher over recent (decadal) versus longer (centennial millennial) timescales. Intrinsic organic matter degradation, long-term climatic ecological changes, anthropogenic impacts on sediment fluxes production may have a role explaining this discrepancy, yet remain poorly understood for freshwater marshes. We collected 4-m core from...
Freshwater marsh restoration can be a viable natural climate solution; however, the extent to which soils bury and preserve organic carbon within policy‐relevant timescales remains highly uncertain. Here, we compare masses accumulation rates from an undrained reference marsh, passively restored freshwater (reflooded after 1954) chronosequence of actively marshes (<10 years in age) situated Lake Erie watersheds Long Point Biosphere Reserve Ontario, Canada. The site has sustained highest...
Peatland soils are of great interest for study and management because their high carbon contents known role in the global cycle. However, stocks have yet to be constrained many wetland ecosystems. Relative bogs, fens saline coastal ecosystems, less is about freshwater marsh despite prevalence, it not well understood how disturbance marshes may affect carbon-climate dynamics. To better understand potential net sinks, we review associated classified, synthesize available data on short-...
