Pariette Wetlands is the oasis of the Uinta Basin. It encompasses 9,033 acres, 2,529 of which are classified wetlands or riparian and is the largest BLM wetland development in Utah. The wetland contains diverse vegetation and wildlife in an arid climate. The site was developed in 1972 to improve waterfowl production and provide seasonal habitat for other species including ring-necked pheasant, mourning dove, sandhill and whooping cranes, and peregrine falcon. A wide variety of raptors including the bald eagle, harrier, and prairie falcon also use the area. Elevated levels of selenium (Se) have been measured in the wetland and there is concern regarding the impact of Se on wildlife. Our research efforts will focus on Selenium (Se) biogeochemistry in the Pariette wetland. This will include measurements of total Se, as well as Se species in wetland soils, sediments, rhizosphere, pore waters, and the water column. Other parameters that influence Se biogeochemistry and Se uptake by plants will be measured. The ultimate goal of this study is to determine the processes responsible for regulating bioavailable Se within the wetland, so as to predict, prevent, and mitigate the potentially toxic build-up of bioavailable Se.
