Map of study locations, barberry patches, and approximate positions of plots. The three detailed location maps are illustrated at the same spatial scale. Plot positions were randomly selected within 5 m of the barberry patch perimeters and away from idiosyncratic habitat features (such as downed tree crowns). Points show the approximate positions within 6 m, because the overstory canopy or topographic features or both reduced the accuracy of global positioning systems.
