The center has evaluated a variety of lethal and nonlethal predator-control methods in an effort to find a strategy that is cost effective and practical for other producers. The most promising strategy tested was selective removal of only sheep-killing coyotes by use of the livestock protection collar, a tool that was banned in California by Proposition 4, a November 1998 ballot initiative.
