Mud Snails Spread to Southern California

Though no one is sure of the eventual impact of mud snail infestations, environmentalists are rightly concerned about their impact on rare and endangered species. That’s why scientists are alarmed about their recent appearance in isolated streams in southern California. “Environmental groups learned last week that the creatures were found during winter bug surveys of Malibu Creek, Las Virgenes Creek, Lindero Canyon Creek and Medea Creek. Malibu Creek is home to two endangered species: the southern steelhead trout and the red-legged frog, which eat insects that could be displaced by the snails.” From the Associated Press.
