Wetland Biome

Fun Fact:

Animal diversity in the wetland biome is greater than in any other biome type.

Wetland biomes are the perfect place for a variety of plants and animals to thrive due to the climate, food availability, and shelter provided. Amphibians and reptiles do particularly well in this environment. Some reptiles, such as turtles, need wetlands because they either live in water for much of their lives or largely rely on water for their survival. Wetlands support a variety of animals that provide plentiful food sources for reptiles. Snakes spend time around rivers and wetlands where there are food sources such as frogs and bird eggs.


Other species that populate the wetland biome are birds. Wetlands are an important habitat for birds that are breeding, nesting, and rearing young, and some bird species, stop to feed in wetlands along their migration route. The value of a wetland to a specific bird species is dependent upon the presence of surface water and the duration and timing of flooding, for example great egrets may nest in trees above water for protection from predators. The geographic location of a wetland also determines how and when birds will use it.


Alligators and crocodiles are the largest animals found in the wetland biome. The type of water found will strongly affect the types of life that survive there. When salt is present in the water, you might find shrimp and shellfish which are some of the smallest wetland animals.

Wetland Biomes

Did you know:

Wetland biomes appear on every continent, except Antarctica.


Wetlands are locatedĀ all over the world, including almost every terrestrial biome from deserts to alpine tundra and all seven continents–except Antarctica. Thriving in many types of climates, wetlands vary in size and can be found both inland and along coasts. The climatic conditions also contribute to the type of wetlands that succeed in certain areas, such as flooded woodlands or watery grasslands.


Wetlands can be found in various locations within the United States, as the map above displays. While the majority of North America’s wetlands are located in the southeast region, other wetlands are also abundant in several northern states, along the east coast, throughout the Mississippi river system, and scatteredĀ in the west.

Wetlands hold a critical significance to each climatic location inhabited worldwide.
