Nathalie's Wetland Biome

Location
Wetlands are found all over the world: along the coast, in lowland areas, or along rivers, lakes, and streams. The largest wetland in the world is in Brazil. In the United States, the largest wetland is the Florida Everglades. Every continent on the planet has a wetland area.

CLIMATE
Wetlands are found in different climates. Tidal wetlands are both in cold coast areas and some are in tropical areas. Inland northern wetlands are filled by melting snow in the Spring and Summer months, and some are created by beaver dams.
Plants
Plants and animals usually grow and work together to make a healthy habitat. One wetland area that I like is freshwater streams and lakes in North America. This wetland has marshes and rivers fed by melting mountain snow. The plants that grow here are grassy meadows, pine forests, birch, willows, cottonwoods, and many shrubs, berries, and wildflowers.
Animals
The beaver's natural habitat is the North American wetland. It has long teeth that do not ever stop growing so they are perfect for cutting down trees. Beavers work hard all day chewing down trees to build river dams with the logs. Beavers make their den (called a lodge) under the dam. Other animals that live in this wetland are salmon, wolves and bears.
INTRODUCTION
fun facts
Scientists call beavers engineers because they dig canals, build dams, and build lodges. They divert water and create ponds. When beavers make a new pond, plants and trees start to grow there. This means more animals move in.

A beaver lodge is a strong and safe home for the beaver family. Sometimes they are over 10 feet tall! The only way to get into a beaver lodge is to swim under the water and find a doorway under the dam. This keeps the beaver pups safe from predators like bears and wolves because they can't find the doorway to get in.
conclusion
Wetlands are the areas between water and land. Some wetlands are covered with water when the tide comes in and out, like tide pools and marshes. Other wetlands are always under water, like swamps and bogs. Wetlands grow plants that are used to living in large amounts of water. Animals that live in wetlands are also used to living with a lot of water and with changes in tide. Some wetlands have salt water, some have freshwater, and some have a mix of freshwater and seawater, called 'brackish' water.

Wetlands are an important part of our Earth's ecosystems because of the special plants and animals that live there. Wetlands are always changing. Sometimes they dry up, re-fill, grow, and move all the time so it is hard for scientists to make a map of all of them.
