Approximate location of camera station transects (colored lines capped with circles) in relation to recreational trails (white lines) in the Cowling Arboretum at Carleton College, Northfield, Minnesota, USA, 2014-2015. Transect symbols have been elongated for visibility and are not to scale. The farthest camera station on each transect was always at least 64 m from any other trail or transect. Cameras and bait were only stationed along one transect at a time. Inset map shows the location of the Arboretum (star) in relation to Minnesota’s major vegetative zones: conifer-hardwood zone (dark gray), deciduous forest-woodland zone (medium gray), and prairie zone (light gray).
