Impact DescriptionNutria (Myocastor coypus) burrows can break through levees that serve to divide rice fields and regulate the water level for small field units. Breaches in these field levees caused by Nutria (Myocastor coypus) result in the water being lost from a unit below the level necessary for good weed control and proper growth of rice. This type of levee damage leads to reduced rice yields, delayed or uneven growth of the crop, or even complete loss.
NotesThis type of damage to water control levees can also impact the growth of sugar cane production.
