This region is far from the coast but still can have storms. The tornadoes that touch down, created from cool and warm air, tear apart buildings and habitats. Throwing them every where picking up animals and creating a barren land. Floods can also be a major problem , they carry chemicals into streams and drown plants and animals. Wildfires usually started by people has control burns , but can be started by others that get out of control burning everything. But wildfires also do some good ,they bring nutrients back into the soil making better for the plants that come back.
