Overcoming Barriers To Aquatic Plant Restoration: Addressing Gaps In Species Identification And Planting Techniques In The Intermountain West, Kate A. Sinnott

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Aquatic ecosystems provide many critical and economically valuable benefits, including drinking water, food, recreational opportunities, and water supply for irrigation and agriculture. However, the health of these systems has been severely impacted by human activities such as pollution, land conversion, and introductions of harmful species. Restoring native aquatic plants can help reverse this damage and reestablish benefits, though it is not a common practice. With an objective to increase capacity for aquatic plant restoration in the Intermountain West, I identified and addressed two major barriers: 1) a lack of confidence in aquatic species identification among wetland professionals, and 2) underdeveloped …

Nutrient Uptake And Water Quality In Great Salt Lake Wetland Impoundments, Rachel L. Buck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Great Salt Lake (GSL) is the largest inland body of water on the Pacific flyway, a major pathway for migratory birds in the Americas that extends from Alaska to Patagonia. The lake is surrounded by approximately 360,000 acres of wetlands, providing critical food, shelter, cover, nesting areas, and protection to between 4–6 million birds that visit each year. Impounded wetlands were created as part of the GSL ecosystem to support waterfowl habitat. These large, shallow, submergent wetlands are diked to control water levels to sustain aquatic plants which are an important food source. Besides providing critical habitat, these impoundments …

Understanding Wetlands And Irrigation In The Little Snake River Basin, Wyoming, Lindsey Washkoviak

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Little Snake River Basin (LSRB) is a managed basin in South-central Wyoming located within the Colorado River watershed facing severe water shortages. There is increased pressure on water resource managers and agricultural producers to adopt water efficiency practices that could negatively affect wetland resources. However, studies have begun to quantify the importance of irrigation for recharging groundwater, maintaining late season instream flows, and maintaining and creating wetlands that provide wildlife habitat and ecosystem services.

In the LSRB there are 11,636 acres of wetlands; 56% of which overlap with irrigation. Conversion to more efficient irrigation could reduce water availability to …
