The Olentangy River at the Wetlands Research Park is part of the local watershed of Columbus, Ohio. This river system creates habitat for many taxonomic groups including: birds, mammals, fish, macro-invertebrates, and plants. With a large body of water, many species of animal depend on this system for clean, quality water. The Wetland Research Park allows for the filtration of this water before it enters the Olentangy River, which can create an overall healthier system.
