Pros and Cons of Long’s Sedge

Sedges are considered good wildlife plants. Sedges are grazed by muskrats, nutria, and rabbits; while the seeds are consumed by waterfowl and small birds. 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.
