Some wetland issues, such as the effects of agricultural toxins on wetlands, have never been subject to extensive study. These toxins are traced from their release into the ecosystem up through the food chain. Researchers are then able to identify any vulnerabilities to toxins in soil, air, water, vegetation and wildlife. The tracking of agricultural toxins includes extensive study of regional wildlife and its interaction with the wetland environment. This has led to improved knowledge of wildlife and waterfowl nesting and breeding patterns, and greater understanding of the impact of prairie farming practices on wetland soil.
Prairie potholes are also an important resource for urban centers.
Wetlands absorb and filter pollutants that would otherwise contaminate the lakes, rivers, reservoirs and aquifers that prairie residents depend on for water supplies. The wetlands also act as a sponge during spring runoff or heavy summer rain, reducing the danger of flooding in populated areas. They provide erosion control and play an important role in recycling nutrients on agricultural land. Researchers are encouraged by the level of interest they have seen in the last couple of years. A number of school groups and local residents have explored the area to find out more about wetlands.
