Kissimmee Prairie Preserve State Park protects the largest remaining tract of the unique Florida dry prairie ecosystem, one of the biologically richest grasslands in the world. Its 54,000 acres contain a mosaic of dry prairie, wet prairie, marshes, sloughs, cabbage palm and oak hammocks, flood plain—no less than 14 distinct natural communities —which support a vast and diverse array of flora and fauna, including a number of endangered or threatened species. It is one of the last places to find the Florida Grasshopper Sparrow, "perhaps the most endangered bird in the continental United States." This is the land made famous by author Patrick Smith in A Land Remembered.
