Preserves are meant to remain for centuries to come. Allocation to alternative purposes is nearly impossible. These parcels are not subject to the state's condemnation statutes. Preserves Five categories of preserves exist in Iowa. Many designated areas qualify for preserve status in more than one category.
Natural Preserves demonstrate Iowa's outstanding biological features.
Some are excellent examples of the prairies and forests that once dominated the state. Others hold plants and animals now rare in Iowa. Dry bluff tops in the Turin Loess Hills form one of the few suitable habitats for one of Iowa's endangered species, the plains pocket mouse. This preserve also marks the northern terminus of many plants typical of the Ozark Plateau. Geological Preserves illustrate Iowa's ancient past.
