Ecological History of Camp Mitigwa

Vegetation History


Iowa is arguably one of the most man-modified landscapes in the world. Of the original vegetation found in Iowa prior to European settlement, less than 10% is left. The rest has been converted for agricultural production. The hydrology of north-central Iowa has been modified to make the pothole wetland region one of the most agriculturally productive in the world.

Most of Camp Mitigwa's property is a forest ecosystem that appears much as it would have as far back as the climate has been the same in Iowa. The flat upland areas on Mitgiwa's west side would have been prairie prior to intensive settlement.
