In honor of National Invasive Species Awareness Week, Sarah Marsh Janish discusses the recent focus on nutria in California. Although this semi-aquatic mammal is not new to California, the surge in population and range across the state is of some concern, especially to those of us who work in the habitats they prefer to inhabit.

Report Nutria: "Suspected observations or potential signs of nutria in California should be photographed and immediately reported to CDFW ONLINE, by email to Invasives@wildlife.ca.gov, or by calling (866) 440-9530."
