Over the last several decades, beaver (Castor canadensis) populations have rapidly increased across Ohio. SW Ohio is characterized by a highly fragmented landscape that is interspersed with agricultural fields, forests, and urban centers. Agricultural runoff and subsequent eutrophication is a major concern within the state. Beavers may potentially be utilized as a best management practice and beneficially engineer stream environments as a low-cost solution to mediate agricultural runoff impacts and increase habitat heterogeneity. Throughout the United States targeted beaver reintroductions are aiming to improve stream and riparian condition. However, few studies have examined where beaver build dams within agriculturally dominated Midwestern landscapes. In order to better predict where beavers are likely to build dams, I will survey public lands within the Great Miami River Watershed and determine the site characteristics of beaver dams. I expect to build a logistic regression model for predicting likely sites of beaver dams using the site characteristics of existing beaver dams.
