Overview

 

Grass, sedge, and /or rush-dominated wetlands on mucky mineral soils that are seasonally inundated and permanently saturated. Shallow emergent marshes occur in similar settings to deep emergent marshes, i.e., in broad, flat areas

bordering low-energy rivers and streams, often in backwater sloughs, or along pond and lake margins. Unlike deep emergent marshes, shallow marshes commonly occur in abandoned beaver flowages, and in some states they are named “Abandoned beaver meadows” or “beaver flowage communities.” The soils are a mixture of organic and mineral components. There is typically a layer of well-decomposed organic muck at the surface overlying mineral soil. There is standing or running water during the growing season and throughout much of the year, but water depth is less than deep emergent marshes and averages less than 6 in.
