Document Summary
Describe main ecosystem services provided by wetland soils. Formation of the redox, or gleying is key factors. Mainly organic material where decomposition has slowed to depalatalization. Wet conditions prevent decomposition, but when you add a lot of oxygen it will decompose and carbon will be released. Wetland loss in the prairies estimated to about 70% due primarily to agriculture. In recent years, ooding had been increasingly problematic. Redistribution of snow and snowmelt runo within hummocky landscapes. These don"t create streams because we don"t get enough precipitation to create these drainage systems. Low conductivity till translates into minimal deep recharge. Once the water is below the biological activity and rooting zone, there is nothing to create the macropores, it has much lower hydraulic conductivity. Ppr is single more important breeding ground for many waterfowl species in north america. Migration habitat for water fowl that breeds in boreal forest and arctic.
