Nutria Pose New Threat To Wildlife, Water In Central California

California has a new water problem, but it's not drought, and it's not endangered fish. Instead it's a roughly 20-pound creature that's described as an "invasive swamp rodent" called the nutria. It's already causing problems in Merced County wetlands and state officials worry the pesky and prolific rodent could further destroy already fragile ecosystems in the Sacramento-San Joaquin River delta and threaten the state's network of canals and levees. Journalist Ryan Sabalow of the Sacramento Bee joined this on Valley Edition to talk about what's being done to address the threat posed by this invasive species in Merced County.
