We assessed the effects of landscape structure on Anaxyrus fowleri (Fowler's Toad) site occupancy using 14 years of call survey data collected from 250 sites in Virginia and Maryland, and landscape variables derived from the National Wetlands Inventory, U.S. Census Bureau, National Land Cover Databases, and U.S. Department of Agriculture. We also conducted a time series analysis on A. fowleri occupancy rates using call survey data collected throughout Virginia and Maryland. We found A. fowleri site occupancy to be negatively affected by deciduous forest, hay crops, development and agricultural pesticides, and we identified a negative interannual trend in occupancy rates between 1999 and 2012.
