This study compares the effect of path width on the gradient of plant species composition change with distance away from a grassland path. I examined two wide and two narrow paths at Jasper Ridge Biological Preserve and compared the magnitude of the gradient of species change away from the path. I hypothesized that wide paths, with presumably higher traffic than narrow paths, would have a more striking gradient of species change than narrow paths. The results support this hypothesis. Wider paths create a greater gradient in surrounding species' abundances than do smaller paths by a factor of almost 18.
