Since 2002, at least 32 mountain lions (collared and uncollared) have been killed by vehicles on the many busy roads, highways, and freeways in the region (as of December 2022).Ĭlick on the links below to learn more about the more notable mountain lion deaths. Twenty-eight out of 29 mountain lions tested in the study have tested positive for one or more anticoagulant compounds and seven have died from anticoagulant rodenticide poisoning (as of December 2021). Researchers believe mountain lions are exposed through secondary or tertiary poisoning, meaning that they consume an animal that ate the bait, such as a ground squirrel, or an animal that ate an animal that consumed the bait, such as a coyote. ![]() Regarding mountain lion mortality, we’ve learned that anticoagulant rodenticide poisoning (rat poisons) is one of the leading causes of death. Two decades of studying mountain lions has provided researchers with a wealth of information. ![]()
