Have you ever heard of Paynes Prairie(大草原)？ It is one of the most important natural and historical areas in Florida. Paynes Prairie is located near Gainesville. It is large, 21,000 acres. This protected land is called a reserve, which is managed by the Florida Park Service.

The Paynes Prairie basin was formed when limestone(石灰石）broke down and the ground settled. It is covered by wet prairie plants. There are areas of open water. During brief periods it was flooded enough to be considered a lake. Except for that, the basin has changed little through time.

Man has lived on Paynes Prairie a very long time. He lived there as far back as 10,000 B.C.. At one time, the Seminoles lived there. The prairie is thought to have been named after King Payne, a Seminole chief. During the late 1600s, the largest farm where cattle are fed in Florida was on Paynes.

William Bartram who lived 200 years ago visited Paynes Praire in 1774. Bartram was the first person who described nature through personal experiences as well as scientific observations. At that time he called Paynes Prairie the “great Alachua Savannah". Most of the animal life, which Bartram described, is still here. A large number of animals live here in winter. The variety of animals is increased by the presence of pine flat woods, wetlands and ponds.

The Paynes Prairie Reserve State Park is open all year round. The Florida Park Service works hard so that the park will appear as it did in the past. It offers many opportunities for entertainment. In the park you can camp and picnic. You can hike and bike. You can boat and fish. You can ride on horses. And you can see Florida as it was in the early days.
