Dr. Greg Pauly, Curator of Herpetology at the Natural History Museum of Los Angeles County, will discuss the ecological consequences of people using rat poisons. Prior research has shown that exposure to rat poisons can be a major conservation concern in raptors and mammals that may prey upon or scavenge poisoned rodents. Dr. Pauly will present results of recent research showing that multiple snake species are also being unintentionally poisoned, highlighting that use of rat poisons can harm the native species that would otherwise be helping to control rodent populations.
