A swamp is a forested wetland. Swamps are special places where land and water meet. They are found all around the world and come in different sizes. The water in swamps can be fresh, a mix of fresh and salt water, or even full seawater.

Freshwater swamps usually form along big rivers or lakes. They need rain and flooding to keep the water levels right. Saltwater swamps grow along warm coastlines in tropical and subtropical areas. Some swamps have small dry areas called hammocks, covered with plants that can survive with their feet in water.

There are mainly two kinds of swamps: "true" swamp forests and "transitional" shrub swamps. In some parts of Canada, people use the word swamp to describe what scientists call a bog, fen, or muskeg. Some of the biggest swamps in the world are found near major rivers like the Amazon, the Mississippi, and the Congo.

Differences between marshes and swamps

Swamps and marshes are special wetlands near water. Marshes are areas often covered by water from rivers or streams, with soft plants growing in them. Swamps are places where the soil stays wet or has water on it, and they grow plants that can handle water, like shrubs, bushes, and trees.

Hydrology

Swamps have soil that stays wet, and water moves very slowly. This water comes from rain, underground sources, ocean tides, and flooding rivers. As the water moves through the swamp, it helps clean the water by trapping dirt and harmful chemicals. Plants in the swamp use some of these chemicals, which helps keep the water pure. Any extra chemicals sink to the bottom and get buried, keeping the swamp a healthy home for many plants and animals.

Values and ecosystem services

Swamps are very important for nature. They help stop flooding by soaking up extra water, which keeps nearby areas safe. The thick plants in swamps hold the soil in place so it doesn't wash away. Swamps give us fresh water and oxygen, and they are good homes for many animals.

People have not always valued swamps as much as fields or forests. In the past, some farmers drained swamps to make more space for crops. But swamps are important for fish. Many of the world's fish and shellfish depend on wetlands to live and grow.

Impacts and conservation

People have drained or filled swamps to make space for buildings and farms. This has caused many swamps to disappear. For example, Louisiana has lost a lot of wetlands, and Europe has lost nearly half of its wetlands.

Swamps are important because they help control floods, clean water, and give homes to many animals.

Today, many places work to protect and restore swamps. In the United States, laws were passed in the 1970s to help save these areas. One way to restore swamps is by closing drainage ditches and removing barriers that stop water from flowing. Conservationists also protect special areas like the swamps in northwest Indiana, such as those in the Indiana Dunes.

Notable examples

Swamps can be found on every continent except Antarctica. The biggest swamp in the world is the Amazon River floodplain. It is important because it has many different kinds of fish and trees.

In Africa, well-known swamp areas include the Sudd and the Okavango Delta. The Bangweulu Floodplains are the largest swamp in Africa. In Asia, there is a big swamp and river system called the Mesopotamian Marshes in southern Iraq. There are also large peat swamps in East Asia and Southeast Asia, especially along coastlines and river valleys. The Vasyugan Swamp in Siberia, part of the Russian Federation, is one of the world's largest swamps.

In North America, the Atchafalaya Swamp at the end of the Mississippi River is the largest swamp in the United States. Other famous swamps in the U.S. include parts of the Everglades, Okefenokee Swamp, and the Great Dismal Swamp. These swamps are important natural areas.

The world's largest wetlands include important swamp areas, such as those in the Amazon and Congo River basins. In colder places, the largest wetlands are often bogs.
