Abstract: 

Between chaparral and grassland vegetation communities is an area called the bare zone where plants fail to thrive. The leading hypothesis explaining the bare zone phenomenon is the intensive granivory of small mammals and birds who preferentially forage near the shrub line because of the protection it affords from predators. In this study I sought to address which animals forage most intensively in the bare zone and the distance they will venture from the chaparral to obtain food. I accomplished this through the use of baited, sooted tracking trays in which I was able to record the kind of granivores which visit the zone and their foraging behavior. While the dominant animal could not be identified, my results showed that there is a significant influence of the porixmity of chaparral on animal activity.
