United States Wetlands Quiz: Quick Study Notes
Wetlands are critical ecosystems found throughout the United States, acting as natural water filters, flood control systems, and wildlife habitats. From the vast “River of Grass” in Florida to the mysterious cypress swamps of the Deep South, American wetlands are as diverse as they are vital.
Forested wetlands dominated by woody plants and trees, such as the Bald Cypress or Tupelo.
Wetlands frequently inundated with water and characterized by herbaceous plants like grasses, reeds, and sedges.
Acidic wetlands that accumulate peat and rely on precipitation for water, typically found in cooler northern climates.
Peat-forming wetlands that receive nutrients from groundwater, supporting a high diversity of plant life.
Key Takeaways
- The Everglades is technically a very wide, slow-moving river, often called the “River of Grass.”
- The primary difference between a swamp and a marsh is the presence of trees (swamps) vs. grasses (marshes).
- The Atchafalaya Basin in Louisiana is the largest river swamp in the United States.
- Mangroves are salt-tolerant trees found primarily in tropical coastal swamps like those in South Florida.

Where is the largest wetland in the United States?
The Everglades in Florida is the largest subtropical wilderness, but the Atchafalaya Basin in Louisiana is the nation’s largest river swamp.
Why are wetlands important to the environment?
Wetlands provide essential ecosystem services including water filtration, flood control, shoreline erosion protection, and habitat for diverse wildlife.
Where are mangrove swamps found in the US?
Mangrove swamps are primarily found in South Florida due to their need for tropical and subtropical climates. They protect coastlines from storm surges.
