Cattails
The scientific name for cattail is Typha; the common cattail is called Typha Latifolia. Cattails are found in North America, Europe, Africa, Asia, and Australia.
Cattails are well suited for survival in swamps. They do not do well on dry land, nor submurged in water, but they flourish in waterlogged soils. They have specialized air channels that allow them to live in oxygen-lacking soil, and air can go through their leaves into the roots. Cattails die if they are not in waterlogged soil, but their seeds are drought-resistant, so they are able to reproduce even in the event of a drought.
Cattails are producers in wetlands; they make their own food. They are edible, to both animals and humans. Muskrats and geese, along with many insects, eat cattails. Native Americans also ate cattails, and built furniture out of their leaves. Typically, cattails are seen as nuisances, but they provide many benefits to wetlands, by filtering runoff, preventing erosion, and providing nesting areas for animals.
