When wetlands are lost, amphibians, fish and many species of birds are at high risk in many areas in the United States. Wetlands can store water during floods which slows the release and reduces erosion. Wetlands are sources of ground and surface water for domestic and agriculture needs. They can filter excess nutrients such as nitrates, chemical contaminants and remove sediments. Many of these functions are in place and are provided to the public at no additional cost.
Wetlands are places of aesthetic value for photography, nature walks and environmental education.
Wetlands can be seen at a number of places. They are often along rivers and streams and in urban settings such as parks. They can be found in the mountains in our national parks, wilderness areas and in state parks. Out on the plains of the Dakotas, prairie potholes provide habitat for over half of the waterfowl in North America. Locally, there will be an opportunity to visit several wetlands in South Platte Park, Cherry Creek State Park, and Two Ponds National Wildlife Refuge in Arvada, Colorado.
