Impact DescriptionNutria (Myocastor coypus) readily eat cattails (Typhn latifolia) shoots and roots. Typically, they "clear cut" stems in a small area rather than feed on stems over a wider area. Giant cutgrass (zizaniopsis milacea), white-water lily (Nymphaea elegans), and pickerel weed (Pontederia cordata) were consumed in Normangee lake, Madison county.
