Comparing Methods of Estimating Fecal-Pellet-Group Density in Woodlots of the Midwestern United States

Abstract Fecal-pellet surveys provide density estimates of pellet groups, which offer a quick and reliable index population densities for white-tailed deer Odocoileus virginianus other wildlife species. Comparisons differing fecal-pellet survey methodologies have previously shown that they vary in the precision. However, researchers made these comparisons outside United States regions with lower densities. In this study, we compared pellet-group precision from line transects, quadrat sampling, strip transects. At each site, three observers surveyed simultaneously being responsible one method. Like studies, found method produced similar density, but sampling most precise estimates. Furthermore, all methods suggested central region Indiana had both highest These results suggest more homogenous distribution groups areas higher densities, may increase methods. Our be effective estimating within woodlots U.S. Midwest, This study not only improves management Midwest provides guidelines studies to potentially advance conservation
