Life of famous California mountain lion sheds light on the dangers humans pose to wildlife, and points to a better way forward.
In December of 2022 the famed Los Angeles mountain lion P-22 was euthanized, following a storied life of urban danger, carnage and mayhem. Much can be said of him; Notably the admiration and pride he inspired in Angelinos and native people who could identify with his will to survive true to his nature, in a world that essentially denies that. Laid to rest in a private tribal ceremony, this mountain lion has become an elder, a teacher, a cautionary tale. Here’s more on the remarkable life of a celebrity mountain lion.
It is known that P-22 survived at least one collision with a motor vehicle. He suffered illnesses related to constant proximity to humans and their chemical counterparts. Rodenticides played a role in his illnesses. The first- and second-generation types of anti-coagulant poisons commonly used today sicken and kill many non-target predators and carrion eaters, including raptors and pets.
P-22 was repeatedly poisoned by rodenticides that sickened him, leading to secondary infections such as mange. See this list of commonly sold rat poisons that you should try to avoid, because of the danger to non-target species!
Audubon Society and the Bio Integral Resource Center‘s Guide: Protecting Raptors from Rodenticides (Common Sense Pest Control Quarterly Special Issue 2011, Published January 2013) offers important insights on how we can take measures and enlist nature’s help to safely reduce rodent populations. It is important to establish an integrated approach, utilizing all available least toxic methods. Innovations such as birth control are being developed to control rats. An example of Biological Control is when we encourage our friends of the forest to feast on rodents by providing improved habitat such as perches and nest boxes. Combining and coordinating multiple approaches is the key to effective Integrated Pest Management.
While a lot is mentioned of secondary poisonings such as occurred with P-22 who suffered years of sub-lethal effects from eating poisoned prey, primary poisonings also exact a cost to non-target species. Primary poisonings occur when an animal directly ingests poison baits. They are designed for palatability, so pets and many other non-target animals can easily be poisoned if allowed access. Non-target species may include woodmice, field voles, bank voles and even insectivorous birds!
Much of this information comes from the BIRC publication: Protecting Raptors from Rodenticides which can be purchased from BIRC at this link: The Integrated Pest Management Specialists.
