What Are Tree Islands?
Tree islands are small forests that sit on land just dry enough for them to take root. But, there’s more to it than that. Everglades tree islands are formed on land that is elevated just slightly, in some cases only by inches!
They can be made of tropical hardwood trees, ferns, cypress, and other topical plant species. Before the Everglades were drained in the 1920’s, the freshwater sheetflow went around the tree islands. As a result, many of them have an elongated, teardrop shape, with the rounded end pointed toward the water flow.
