Stop 2: Pothole Wetland The pothole wetland located on the Loblolly Marsh Wetland Preserve is a rare example of what used to be quite common across Indiana and other midwestern states. Some people estimate that between 60 and 98 percent of wetlands that were here in 1850 have now been destroyed. Most of these destroyed wetlands were pothole wetlands. Erosion became a problem for the land surrounding the destroyed wetlands. As farming increased, layers of minerals in the soil began to collect in places like the Loblolly Marsh. A thick layer of soil rich in minerals now rests on top of the traditional organic top layer.
Why shouldn't we destroy wetlands?
