Welcome to UNI's Biological Preserves

The University of Northern Iowa Biological Preserves System is an 88-acre complex of diverse natural and reconstructed habitats. With the adoption of Clay Prairie in the 1960’s, the Biological Preserves Program was initiated in 1970 after the appointment of a committee within the Department of Biology to develop, manage, and regulate the use of the system. Welcoming visitors in all seasons, the system includes 5.8 miles of regularly maintained trails winding through diverse landscapes and ecosystems including; mixed grass prairie, tall grass prairie, lowland forest, and upland forest.
