What are the Everglades?

The Everglades are subtropical marshes in south Florida, southeast of the United States. Their area exceeds 7000 km². In places the cutting grass is sometimes 4 m high. Elsewhere, there are salt marshes and mangroves. Before the seminole Indians took refuge there around 1840, no one lived in this region. Partly drained for use in agriculture, the region is now a national park where you can see turtles, alligators and many species of birds.
