HOW DOES EUTROPHICATION IMPACT AQUATIC VEGETATION IN BOTH RURAL AND URBAN SPRING-FED PONDS?
In the Ozarks region of Missouri and Arkansas, there are numerous springs that are commonly impounded to create ponds for agricultural and recreational use. Spring-fed ponds are often susceptible to eutrophication, which can have large impacts on their aquatic plant communities. High nutrient levels (nitrogen and phosphorous) can lead to high turbidity, low submerged plant abundance, and high abundance of nuisance vegetation. These problems lend themselves to difficulties in recreational activities, a decrease in the natural aesthetic, and greatly decrease water quality. Although rural and urban ponds have different sources of pollution, both can exhibit the same symptoms of low water quality. We surveyed 11 spring-fed ponds, 6 rural and 5 urban, to compare plant communities and water quality. We expected to find higher plant diversity in rural ponds and lower diversity in ponds with higher nutrient concentrations. As expected, we found a pattern of higher species diversity in rural ponds. However, the ponds with the highest nutrient concentrations also had the highest species diversity. We suspect that other factors may be contributing to the difference in species diversity, such as physical characteristics like surface area and depth.
