Abstract

Aquatic macrophytes are macroscopic aquatic plants that play an important role in the health of aquatic ecosystems. Not only do macrophytes provide vital structural support in aquatic ecosystems (1), but they also contribute toward food production, nutrient regeneration, and habitat for a wide range of organisms. Because of their roles in aquatic ecosystem health, aquatic macrophytes can be utilized as indicators of stream health (2). In fact, aquatic macrophytes may be indicative of a variety of ecosystem stressors including nutrient runoff, changes in hydrologic regime, and exotic species invasion (3, 4). Therefore, species richness of aquatic macrophytes, their composition, and density have all been incorporated into different macrophyte indicators (5, 6). As such, bioindicators estimate the pollutants affecting the biota in an ecosystem and are purely qualitative in nature.
