“…As many as 60% of the wetlands had at least one pesticide in amounts that exceeded Canadian guidelines for the protection of aquatic life. Lindane and triallate exceeded these guidelines most often (Donald et al 1999). (Donald et al 1999).…”

“…In a study in southern Saskatchewan, Donald et al (1999) found that in early July the average number of types of pesticides detected in wetlands ranged from 1.8 in areas with less than 21 mm of rain during the previous 15 days, to 3.2 in areas with more rainfall. High rainfall lead to greater erosion.…”

“…These wetlands also deliver numerous ecosystem services, including surface-water storage and flooddamage protection, ground-water recharge, and global cycling of nutrients (van der Kamp and Hayashi 1998;Tiner 2003;Smith et al 2011). Many of these wetlands are completely surrounded by upland and are highly vulnerable to land conversion, habitat fragmentation, water pollution, ground-water withdrawal, and drought (Donald et al 1999;Gleason et al 2003;Tiner 2003). Sediment accumulation can also threaten the viability and hydrologic functioning of many wetlands embedded within the agricultural landscapes of the Great Plains (Smith et al 2011;Burris and Skagen 2012;Daniel et al 2014).…”

Sediment Accumulation in Prairie Wetlands under a Changing Climate: the Relative Roles of Landscape and Precipitation

Sediment accumulation threatens the viability and hydrologic functioning of many naturally formed depressional wetlands across the interior regions of North America. These wetlands provide many ecosystem services and vital habitats for diverse plant and animal communities. Climate change may further impact sediment accumulation rates in the context of current land use patterns. We estimated sediment accretion in wetlands within a region renowned for its large populations of breeding waterfowl and migrant shorebirds and examined the relative roles of precipitation and land use context in the sedimentation process. We modeled rates of sediment accumulation from 1971 through 2100 using the Revised Universal Soil Loss Equation (RUSLE) with a sediment delivery ratio and the Unit Stream Power Erosion Deposition model (USPED). These models predicted that by 2100, 21-33 % of wetlands filled completely with sediment and 27-46 % filled by half with sediments; estimates are consistent with measured sediment accumulation rates in the region reported by empirical studies. Sediment accumulation rates were strongly influenced by size of the catchment, greater coverage of tilled landscape within the catchment, and steeper slopes. Conservation efforts that incorporate the relative risk of infilling of wetlands with sediments, thus emphasizing areas of high topographic relief and large watersheds, may benefit wetland-dependent biota.
