Abstract: Aquatic ecosystems play a vital role in ecosystem balance, yet their health can be compromised by overgrowth of certain surface plant species like duckweed, watermeal, and filamentous algae. Understanding the factors contributing to such overgrowth is crucial for effective conservation strategies. This study aimed to investigate the relationship between nutrient levels and the presence of duckweed, watermeal, and filamentous algae in ponds at the Cincinnati Nature Center. Building on existing research linking high nutrient levels to excessive aquatic plant growth, our specific goal was to compare nutrient concentrations in three ponds exhibiting different plant compositions. Water samples were collected from multiple locations within the three ponds over four weeks and analyzed for phosphates, nitrates, and ammonium. Statistical analyses revealed significant differences in nutrient levels among the ponds. The findings indicate higher nutrient concentrations in ponds with duckweed and watermeal and filamentous algae compared to those without, supporting the hypothesis of a direct correlation between nutrient levels and the presence of these specific surface plants. Despite limitations such as sample size and environmental variability, this study provides valuable insights for conservation efforts. Future research could explore seasonal variations in nutrient levels and the influence of submerged aquatic plants on duckweed growth. Ultimately, this interdisciplinary approach contributes to broader understandings of ecosystem dynamics, guiding management strategies for sustainable environmental stewardship.
