AUTHORS: Jay Vecchiet, Richard B. King – Northern Illinois University

ABSTRACT: Agencies across the United States rely on data driven management practices. Whether or not those practices are successful can be ambiguous because variables other than management also shape population and community responses. Here, we test whether the effects of preserve size, preserve land cover, surrounding land cover, habitat quality, and management history have a detectable effect on species richness. We focus on amphibians and reptiles in grassland-dominated preserves in northern Illinois.  Species lists were compiled for 15 preserves ranging in size from 7 ha to 1460 ha. Habitat quality and land cover (open water, wetland, grassland, wooded, agriculture) of all preserves were analyzed using ArcMap 10.4.1. Preserves were also classified by age, prior land use, and intensity of management actions (seeding, prescribed fire, chemical and mechanical controls). Across preserves, a total of 31 amphibian and reptile species were documented, including 8 frogs and toads, 2 salamanders, 2 lizards, 6 turtles, and 13 snakes. Of these, 7 are considered Endangered, Threatened, or Species in Greatest Conservation Need in Illinois. As management is carried out, there are obvious positive effects on the environment (soil composition, plant communities, water quality), but demonstrating a positive effect on organisms with cryptic life histories, such as amphibians and reptiles, is challenging.
