Everglades

The Everglades is a big, wet land.

It is a field of grass in Florida. The water moves very slowly. It flows from a big lake.

This water moves toward the sea. The ground is made of rock. This rock holds water like a sponge. This helps the plants grow.

It is a very special place for nature.

The Everglades is a large area of flooded grasslands. It is in southern Florida.

This place is a special system of water. It starts near Orlando at the Kissimmee River. The river flows into Lake Okeechobee. This lake is very big but also very shallow.

During the wet season, water leaves the lake. It forms a slow river. This water flows south over a limestone shelf. The water ends at Florida Bay.

The ground is made of limestone. This is a type of rock. Many layers of shells and sand made this rock. Some parts of the rock are porous. This means they have tiny holes. These holes act like a sponge. The rock stores water during the dry season. This helps the plants and animals.

Much of the land has changed over time. People built canals and farms. Now, many groups work to fix the water. They want to help the Everglades stay healthy.

The Everglades is a huge region of flooded grasslands in southern Florida. It is a very special natural system that covers much of the southern part of the state.

This area is important because it helps manage water for many living things. The water moves through a large drainage basin, which is a group of lands that drain into one place. It is part of a large group of tropical lands called the Neotropical realm. Understanding how this water moves helps us see why the region is so unique.

The water follows a very specific path to reach the ocean. It begins near Orlando at the Kissimmee River. This river flows into a massive but shallow body of water called Lake Okeechobee.

During the wet season, water leaves the lake and forms a slow-moving river. This water flows southward across a limestone shelf. Finally, the water reaches Florida Bay at the very bottom of the state.

People have lived in this part of Florida for a very long time. Humans have been in the southern peninsula for 15,000 years.

Before Europeans arrived, the Calusa and Tequesta tribes lived there. Later, the Seminole people created a new culture in the region. They moved into the Everglades during the Seminole Wars in the early 1800s. They even resisted being moved away by the United States Army.

Over the last hundred years, the land has changed a lot. In 1848, people first suggested draining the land for farms. By 1882, work on this actually began.

During the 1900s, many canals were built to help the local economy grow. In 1947, Congress created the Central and Southern Florida Flood Control Project. This project used levees and water control devices to manage the flow. Today, about 50 percent of the original Everglades has been turned into cities or farms.

Nature is also built on a foundation of old rock. The ground is made of layers of limestone, sand, and shells. This rock was formed millions of years ago when Florida was part of a supercontinent called Gondwana.

Some types of limestone, like the Miami Limestone, are very porous. This means they have tiny holes that act like a sponge to hold water. This stored water is very important during the dry season. This rock also helps provide fresh water to the people living in Miami.

The Everglades is a massive natural region of flooded grasslands located in southern Florida. It functions as a large drainage basin within the Neotropical realm. This system is vital because it manages the movement of water across a vast landscape. The region is defined by its unique hydrology and complex geological foundation. Understanding the Everglades requires looking at how water, rock, and history intersect.

The movement of water through this system follows a specific, slow-moving path. It begins near Orlando with the Kissimmee River. This river discharges into Lake Okeechobee, which is a very large but shallow lake. During the wet season, water spills out of the lake to form a wide, slow-moving river. This water flows southward across a limestone shelf toward Florida Bay. This natural flow creates the marshland environment seen today.

Geology plays a massive role in how the Everglades functions. The region sits atop layers of porous limestone, which is rock filled with tiny holes. This rock was formed through millions of years of shifting sea levels and sediment buildup. About 300 million years ago, the crust under Florida was part of the supercontinent Gondwana. As North America merged with Africa, the Florida Platform became a shallow marine environment. Over time, layers of calcium carbonate, sand, and shells compressed into limestone.

Several distinct geologic formations shape the southern Florida landscape. The Tamiami Formation consists of highly permeable sands and quartz. Below Lake Okeechobee lies the Caloosahatchee Formation, which is composed of sandy shell marl and clay. The Fort Thompson Formation is made of dense, hard limestone and sand. Near metropolitan areas, the Anastasia Formation contains shelly limestone and coquina. The Miami Limestone is particularly important because it is highly porous. This limestone stores water during the dry season and influences which plants can grow.

Human history in this region spans at least 15,000 years. Long before European colonization, the Calusa and Tequesta tribes inhabited the area. During the early 19th century, the Seminole people moved into the Everglades during the Seminole Wars. They assimilated other groups and created a new culture while resisting removal by the U.S. Army. In the 1800s, migrants proposed draining the land for plantations. By the mid-20th century, massive engineering projects changed the landscape forever.

In the 20th century, human development significantly altered the ecosystem. Many canals were built to spur the South Florida economy and support land development. In 1947, Congress formed the Central and Southern Florida Flood Control Project. This project utilized levees and water control devices to manage flooding. As the Miami metropolitan area grew, Everglades water was diverted to supply cities. Consequently, about 50 percent of the original Everglades has been lost to urban or agricultural use. Much of this land is now used for sugarcane farming.

Today, conservation efforts focus on restoring the natural balance of the region. In the 1970s, environmental groups began paying closer attention to the ecosystem. The Everglades was eventually designated as a Wetland Area of Global Importance by UNESCO. In 2000, Congress approved the Comprehensive Everglades Restoration Plan. This was considered the most expensive and comprehensive restoration attempt in history. Efforts include removing canals to allow rivers like the Kissimmee to flow naturally again.

The health of the Everglades is directly connected to the quality of life in South Florida. Poor water quality in Lake Okeechobee can impact urban areas. Furthermore, the Everglades helps replenish the Biscayne Aquifer. This aquifer is a primary source of fresh water for the Miami metropolitan area. By protecting the wetlands, people also protect their own water supply. The struggle to balance development with sustainability remains a major challenge for the region.
