A prairie is an area of land covered by grasses, flowers, and other non-woody vegetation. It is a flat or gently rolling landscape found primarily in the central regions of North America. Prairies are important ecosystems that support a variety of plant and animal species.
A marsh is a type of wetland. Other types of wetlands include swamps, bogs, fens, forested wetlands, and others. A marsh is almost always inundated, or full of water. There is usually some open water present. Vegetation such as grasses, reeds, and forbs dominate the marsh landscape. This contrasts with swamps that are generally deeper and have more trees.
A flat area of land at low elevation covered with grasses is typically referred to as a "plain." Plains can vary in size and are common landscapes found in various parts of the world. They are characterized by their relatively flat topography and abundant grass vegetation.
