Ruth Herzberg and John Pearson work, respectively, for the Forest and Prairies Division at the State Forest Nursery in Ames and for the Parks, Recreation and Preserves Division, Iowa Department of Natural Resources, in Des Moines.
The Iowa state preserves system was created in 1965; a decade later, thirty preserves had been dedicated, including "six native prairies, a native White Pine stand, the state's only Sphagnum bog, a Balsam Fir stand, some of the oldest exposed rock outcrops in the world, an ancient fort, a fen, several Indian mound groups and a historical cemetery." This new guide to all ninety Iowa state preserves -- biological, geological, archaeological, historical, and scenic -- describes the state's most treasured prairies and forests, quartzite outcrops and ice caves, and Indian mounds and wetlands as well as such historic sites as Fort Atkinson and Montauk.
