Live traps for beavers (Castor canadensis and C. fiber) will be more important as leg-hold and killer traps become outlawed. But live traps are potentially dangerous to personnel because the safety mechanism permits the trap to shut prematurely. To make these traps safer, we redesigned the safety mechanism so that the handler does not have to reach inside the trap to set it. We separated the (internal) trigger mechanism from the safety mechanism. We installed a safety mechanism on the outside of the trap. The new mechanism is described. We have used it in the field for 6 years and experienced no accidents.
