Marsh, Swamp, Wetland, Bog- What’s The Difference?

Famous Swamps Around The WorldHere in Louisiana we know wetlands. As a matter of fact, the Atchafalaya Basin, which is a combination of wetlands and river delta areas where the Atchafalaya River and the Gulf of Mexico converge, is the nation’s largest river swamp, containing almost one million acres of the nation’s most significant bottomland hardwoods, swamps, bayous and backwater lakes. Have you ever wondered if there is a difference between marshes, swamps and bogs?


Marshes are usually defined as nutrient-rich wetlands which support a variety of reeds and grasses. These areas are consistently flooded with water. Many marshes are freshwater, and exist in areas with poor drainage—along streambeds, lakes, and ponds. Since soil is consistently wet from flooding, marshes are extremely nutrient-rich, and can support a wide variety of plant and animal life. Marshes can also be tidal, according to experts. Saltwater marshes are saturated every time the tide comes in from the ocean. There are some marshes that are fed by groundwater.  They also get saturated from rain water.  Marshes are typically not as deep as swamps.


A swamp is a place where the plants that make up the area covered in water are primarily woody plants or trees. Woody plants may include trees such as the cypress, cedar, or mangrove. Swamps can also be dominated by shrubs such as the buttonbush. Swamps are fed by groundwater or surface water.


Bogs are characterized by their poor soil and high peat content. That’s why they usually do not support large plants.  A bog is created over hundreds or thousands of years. It forms when plants decays in a lake and fill it. This creates layers and layers of peat. Bogs are freshwater, and in spite of the large amounts of decaying plant matter, they are very poor in nutrients because of the slow rate of decay. Most of the plant life around a bog are fungi, mosses, and small shrubs. Many carnivorous plants including pitcher plant and sundew, grow in bogs because of the low nutrient levels in the soil.
