How has nutria changed the ecological balance of the food web since it was introduced?

Nutria, originally from South America, have significantly disrupted the ecological balance in the regions where they were introduced, particularly in wetlands. Their voracious feeding habits lead to the overgrazing of aquatic plants, which are crucial for stabilizing soil and providing habitat for various species. This reduction in vegetation not only diminishes habitat for native wildlife but also contributes to increased erosion and nutrient runoff, further degrading the ecosystem. As a result, the decline in plant diversity and the alteration of habitat structures have cascading effects throughout the food web.
