Pros and Cons of Arrowhead

The tubers of arrowheads are prized foods by ducks, geese, muskrats, and nutria. Seeds are sometimes consumed by ducks. Submerged portions of all aquatic plants provide habitats for many micro and macro invertebrates. These invertebrates in turn are used as food by fish and other wildlife species (e.g. amphibians, reptiles, ducks, etc.). After aquatic plants die, their decomposition by bacteria and fungi provides food (called “detritus”) for many aquatic invertebrates.
