Abstract

Capture and transportation of wild rodents is needed to supply study animals for laboratory or enclosure studies and for translocation of threatened and endangered species. Stress of captured rodents must be minimized to maximize survival. Methods to limit stress include minimizing capture and transportation durations, providing sufficiently sized housing with adequate nesting materials and foods, and ensuring that animals are maintained in comfortable environmental conditions. We utilized these techniques to capture and transport California voles (Microtus californicus) and pocket gophers (Thomomys bottae) from California to Colorado to determine their rate of survival during this process. We captured pocket gophers through live-trapping; burrow excavation substantially reduced capture and holding times for voles. All 50 voles and 88 of 91 pocket gophers were still alive and in good condition 2 weeks postarrival. The techniques and materials described should provide a useful framework for other wild rodents as well.
