Typha is an iconic wetland plant found worldwide. Hybridization and anthropogenic disturbances have resulted in large increases abundance ecosystems throughout North America at a cost to native floral faunal biodiversity. As demonstrated by three regional case studies, capable of rapidly colonizing habitats forming monodominant vegetation stands due traits such as robust size, rapid growth rate, rhizomatic expansion. Increased nutrient inputs into wetlands altered hydrologic regimes are...
Inland waters are increasingly recognized as critical sites of methane emissions to the atmosphere, but biogeochemical reactions driving such fluxes less well understood. The Prairie Pothole Region (PPR) North America is one largest wetland complexes in world, containing millions small, shallow wetlands. sediment pore PPR wetlands contain some highest concentrations dissolved organic carbon (DOC) and sulfur species ever recorded terrestrial aquatic environments. Using a suite geochemical...
Natural methane (CH4) emissions from aquatic ecosystems may rise because of human-induced climate warming, although the magnitude increase is highly uncertain. Using an exceptionally large CH4 flux dataset (~19,000 chamber measurements) and remotely sensed information, we modeled plot- landscape-scale wetland Prairie Pothole Region (PPR), North America's largest complex. Plot-scale were driven by hydrology, temperature, vegetation, size. Historically, PPR largely dependent on total extent....
Implementation of the U.S. Department Agriculture (USDA) Conservation Reserve Program (CRP) and Wetlands (WRP) has resulted in restoration >2 million ha wetland grassland habitats Prairie Pothole Region (PPR). Restoration through these programs provides diverse ecosystem services to society, but few investigators have evaluated environmental benefits achieved by programs. We describe changes processes, functions, that occur when wetlands adjacent uplands on agricultural lands are restored...
Impacts of land use, specifically soil disturbance, are linked to reductions organic carbon (SOC) stocks. Correspondingly, ecosystem restoration is promoted sequester SOC mitigate anthropogenic greenhouse gas emissions, which exacerbating global climate change. Restored wetlands have relatively high potential compared other ecosystems, but accumulation rates variable, leads uncertainty in sequestration rates. To assess properties and freshwater mineral wetlands, we analyzed an extensive...
Executive Summary Concern over flooding along rivers in the Prairie Pothole Region has stimulated interest developing spatially distributed hydrologic models to simulate effects of wetland water storage on peak river flows. Such require spatial data volume and interception area existing restorable wetlands watershed interest. In most cases, information these model inputs is lacking because resolution topographic maps inadequate estimate areas wetlands. Consequently, studies have relied or...
The Williston Basin, which includes parts of Montana, North Dakota, and South Dakota in the United States provinces Manitoba Saskatchewan Canada, has been a leading domestic oil gas producing region for more than one-half century. Currently, there are renewed efforts to develop resources from deep geologic formations, spurred by advances recovery technologies economic incentives associated with price oil. Domestic production many benefits provides means fulfill part energy demands; however,...
Hydrologic margins of wetlands are narrow, transient zones between inundated and dry areas. As water levels fluctuate, the dynamic hydrology at may impact wetland greenhouse gas (GHG) fluxes that sensitive to soil saturation. The Prairie Pothole Region North America consists millions seasonally-ponded ideal for studying hydrologic transition states. Using a long-term GHG database with biweekly flux measurements from 88 seasonal wetlands, we categorized each sample event into wet (W→W),...
Abstract The enhancement of agricultural lands through the use artificial drainage systems is a common practice throughout United States, and recently this has expanded in Prairie Pothole Region. Many wetlands are afforded protection from direct effects regulation or legal agreements, setback distances typically used to provide buffer between systems. A field study was initiated assess potential for subsurface affect wetland surface-water characteristics reduction precipitation runoff,...
Wetlands deliver a suite of ecosystem services to society. Anthropogenic activities, such as wetland drainage, have resulted in considerable loss and degradation, diminishing the intrinsic value ecosystems worldwide. Protecting remaining wetlands restoring degraded are common management practices preserve reclaim benefits Accordingly, methods for monitoring assessing required evaluate their ecologic condition outcomes restoration activities. We used an established methodology conducting...
