Where Does it Grow?

Soft rush can be found in moist, sandy soil or the shallow fresh water of ponds and lakes, along streams, sloughs, and in marshes.

Pros and Cons of Soft Rush

Waterfowl, game birds, and song birds will consume seeds of soft rush (and other rushes). 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.
