Thank you, Mr. Chair, and my thanks to our witnesses today. It's very interesting once again.
Dr. Guyn, you responded in one of your questions that the restoration of wetlands in some cases can be relatively easy. You said that in some cases earth plugs are all it takes. When you say it's relatively easy to do, what kinds of timeframes would be required for a functional wetland? It may not be completely restored, but it would be starting to contribute to the work that a wetland can do.
