Abstract:Many species of wildlife occur along roads. Most rodents spend their entire lives within the rights-of-way (ROWs); larger species are transients which feed within ROWs. Mowing affects abundance of rodents. Species preferring denser cover were more plentiful in un-mowed ROWs than in mowed-ROWs. Species preferring sparse cover were more abundant in mowed ROWs than in un-mowed ROWs. Rodent diversity was greater in less-disturbed habitats (old fields). The types of vegetation occurring in an area influence rodent diversity and abundance.
