A unique wetland in northwest Iowa was turned into farmland. A conservation easement is reviving it.
A unique wetland in northwest Iowa was once drained, then heavily farmed for 70 years.
Now, it’s showing early signs of a return.
In the early 1990s, botanists at the Iowa Department of Natural Resources wanted to locate fens across the state. Regular wetlands are usually fed by surface water from rivers, streams and lakes, but a fen is a type of wetland fed by groundwater.
The botanists knew of three fens in northern Iowa, but they soon identified about 200 more around the state.
