The study aimed to improve water quality in Sacramento Valley wetlands impacted by waterfowl droppings. Researchers used a model to simulate wetland conditions and bird behavior, finding that water availability and temperature affect nitrogen removal. Waterfowl populations influence water quality, with more birds leading to higher nitrogen levels. Increasing temperature decreases bird populations, resulting in lower nitrogen concentrations. The model can help understand how wetland management affects water balance, quality, and vegetation, showing the importance of managing water resources for healthy wetlands.
