Overview

Tall graminoid/emergent herbaceous wetlands occurring on saturated, mucky mineral soils that are seasonally inundated and permanently saturated

Deep emergent marshes generally form in broad, flat areas bordering low-energy rivers and streams or along pond and lake margins. 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. Water depth averages between 6 in. and 3 ft. Deep emergent marshes are associated with shrub swamps, and the two communities intergrade.

narrow-leaved cat-tail (Typha angustifolia) (The easiest way to tell narrow-leaved cattail from broad-leaved is to look for this green gap between the staminate and pistillate parts of the spike. There is a very short one in broad-leaved cattail, so that the staminate and pistillate parts are practically close together. The color of the ripe narrow-leaved spike is much like milk chocolate, while in broad-leaved it's more like dark chocolate.)
