Small Vertebrate Underpass Study

In 2012, the small animal connectivity study began as part of Connectivity Monitoring Strategic Plan (CMSP) developed by the San Diego Monitoring and Management Program (SDMMP). There were three main objectives in this study. First, to determine which groups of small vertebrates are currently using or avoiding these wildlife underpasses and understand how these behaviors may be predicted by life history characteristics. Secondly, to investigate the effectiveness of adding cover structures to underpasses as a way to enhance small vertebrate use of underpasses. Third, to evaluate the extent to which larger vertebrates often used as focus species in connectivity studies in the region act as indicators of use by small vertebrate species.
