Pros and Cons of Yellow Water Lily

Deer occasionally consume the leaves of yellow water lilies; while ducks consume the seeds and roots, as do muskrats, nutria, and other rodents. 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.
