Anthropogenic alteration of wild areas impacts native wildlife through habitat loss and fragmentation. Habitat fragmentation divides natural areas into smaller patches with less connectivity, homogeneity, and quality compared to the original larger patch.  We examined the effects of an artificial corridor created as a right-of-way for power lines that bisects a wooded area on the campus of Georgia Gwinnett College (GGC) in Lawrenceville, GA. The power line cut differs from the wooded areas on either side in plant diversity and ground and canopy cover. We examined the effects of this corridor on the diversity and movement of mammals by comparing the three habitat types using Sherman small mammal traps and trail cameras. Small mammals were captured and marked once a season for a year. Baited trail cameras were monitored for one month. Although diversity was low, habitats differed in the types of mammals visiting and the time spent there. No small mammals were found to cross the power line cut and move from one wooded area to the other. Therefore, we conclude that this artificial corridor impacts the diversity and movement of mammals in this landscape.
