Over time, this erosion results in a cavity underneath the pavement. Sinkholes are often observed as an area that has a sudden and often significant drop in elevation, sometimes resulting in a complete open cavity that may pose significant liability risk.

With respect to agronomic attributes of lands undergoing grassland conversion, corn/soy production is expanding onto marginal lands characterized by high erosion risk and vulnerability to drought. Grassland conversion is also concentrated in close proximity to wetlands, posing a threat to waterfowl breeding in the Prairie Pothole Region.
