Use of Remote Cameras in Riparian Areas: Challenges and Solutions.

Remote photography has become a popular tool in wildlife research. The technique is especially valuable in monitoring elusive, free-ranging carnivores, which often are difficult to detect. We used remote cameras and video cameras manufactured by Trailmaster to monitor river otters (Lontra canadensis) at latrines in Pennsylvania and Maryland from October 2002 to July 2004. Remote cameras previously have not been used to study river otters or other animals in riparian areas. We offer new solutions to many of the general problems encountered while using remote cameras, and to the previously undocumented difficulties that arise while using the devices in riparian areas. The techniques presented here will enable future researchers using remote cameras to increase the quality of data obtained.
