A study focused on the population dynamics and food habits of yellow-bellied marmots (Marmota flaviventris) was investigated at Sierra Summit Ski Area, Lakeshore, CA, USA during the summers of 1993 and 1994. Live trapping of the yellow-bellied marmots was the preferred method of collecting data for this project and it was estimated that a minimum of 14 traps were needed to adequately cover the study site. However, there were a limited number of commercially-built wire traps available, thus the need to construct box traps made of plywood. Approximately 45 min was required to construct a wooden box trap. Yellow-bellied marmots were successfully captured in all 11 wooden box traps throughout the study period. Seventy-eight percent of the 117 captured marmots were caught in the wooden box traps. In addition, there was a statistically significant (chi-square, P < 0.05) difference in trap type success between the commercial wire traps and the wooden box traps. The wooden box traps higher capture rate may be due to trap preparation before baiting and the amount of cover provided by the trap.
