What Distinguishes a Bog From a Marsh?

Bogs and marshes are both types of wetlands. Wetlands are typically inhabited by waterfowl, and over the years have typically been shrouded in mystery. Throughout history, they've been associated with magic and the occult. Geographically, wetlands are distinguished by the water table being close to or above ground level. With much water available, wetlands are usually teeming with life.

Marshes
- Marshes are wetlands characterized by the presence of grasses. They are treeless. Marshes are most easily found across the United States and Canada. These marshes are some of the most important natural habitats for waterfowl, such as ducks, geese and swans.
Bogs
- Bogs are characterized by the presence of poorly-drained peat. Peat moss is also usually abundant. Bogs are often harvested for both peat and the accompanying moss. Respectively, they're used as fuel and soil conditioner. The presence of peat actually makes bogs hostile to the growth of microbial life.
Landscape and Geography
- The landscape and geography of a wetland can give away its type. Bogs are common in Canada and Ireland, but are somewhat rare across the United States. Also, marshes are treeless while bogs usually include various species of conifer such as spruces.
Wildlife
- Marshes and bogs also can be differentiated by the presence of various waterfowl. The water in bogs is generally covered with sphagnum, or dead plant matter. This can be off-putting to many waterfowl. Bogs sport much wildlife in the way of reptiles and insects.
