Michigan native plants evolved with fire as a result of most of the state burning every 5-10 years in resettlement times. Fire returns nutrients to the soil, allows for more solar radiation to reach the ground which quickens spring green up, and can kill non native plants that did not evolved with fire. See this two minute video https://youtu.be/lKl4IibVDCg on a residential prescribed burn on a quarter acre lot. Three rain gardens, a couple perennial beds, and a buffalo grass lawn.
