According to a new study released by University of Waterloo (Ontario, CA) professor Nandita Basu, small wetlands seem to be more efficient at reducing nutrient loading. His team reviewed 600 studies worldwide of wetlands rivers and reservoirs. They concluded that smaller wetlands are more effective as “nutrient sinks” because they have more soil that filters less water.
These findings are particularly important for Wisconsin because too much nitrogen and phosphorus cause the algae blooms that poison our lakes.
The way you manage runoff from your land affects the land and waters that are downhill. Small wetland restorations high in the watershed make a big difference. Restoration contractors and consultants can help you figure out the best practices to manage nutrient runoff.
Wetland restoration can be complicated. Moving soil and many other activities in wetlands require the right licenses and permits. Look for a professional who is trained in wetland ecology and has a proven track record doing wetland projects. Make sure to ask for and check out their references.
The Wisconsin Wetlands Association is a great first stop to find information about out wetlands. They not only have general information about wetlands, they provide really good resources for private landowners. The Wisconsin DNR has an online Wetland Restoration Handbook that has chapters to walk you through the entire restoration process.
Wisconsin’s wetlands are so much more than cattails. You will be amazed at how easy it is to fall in love with your swamp.
