The most common types of wetlands are marshes, swamps, bogs, and floodplains. Marshes are dominated by grasses and other low-growing plants that can tolerate periodic inundation from flooding. Swamps are similar to marshes but typically have a higher concentration of trees and shrubs. Bogs are characterized by acidic soils and spongy vegetation. Floodplains are areas where water flows across the land, often forming temporary lakes or ponds.
