be found in the Final Environmental Impact Statement for Kisatchie, prepared by the Forest Service in 1999. Although forests dominate the landscape, scattered prairies can also be found. Natural prairies have been almost extirpated from Louisiana, mostly by clearing for agriculture. Less than one thousand acres of calcareous prairie may remain in the entire state, three pieces of which are associated with Kisatchie: the Kieffer prairie (769 acres), the historic Tancock Prairie (45 acres), and the historic Bartram Prairie (1,190 acres). The latter two are referred to as "historic" because they were mentioned in 1836 survey records; they have reverted to forest. So thoroughly have the prairies of North America been cleared that remnants such as these are likely to be of national significance. The restoration of a natural fire regimen is the most important priority for maintaining and enhancing these prairies. The forest consists of several large areas; and these are fragmented by private land ownership. The headquarters are in Pineville, but the Kisatchie National Forest has five ranger districts in the north-central area of the state: Calcasieu, Caney, Catahoula, Kisatchie and Winn. The forest lies in parts of seven parishes. In descending order of land area within the forest, they are Grant, Natchitoches, Winn, Rapides, Vernon, Claiborne, and Webster parishes. Calcasieu Ranger District The Calcasieu Ranger district is the southernmost district, located between Alexandria, Leesville and DeRidder. The District Office is located on LA 28 West, two miles (3 km) east of Gardner and ten miles (16 km) west of Alexandria, Louisiana. Wolf Rock Cave, the only known cave in Louisiana, is located just off Parish road 455 (locally known as Johnsonville road) in Vernon Parish. The 70 foot above ground cave is situated beside Bundick Creek and is a protected by two rock overhangs. The Palustris Experimental Forest is located within the Calcasieu Ranger District. The district comprises the Evangeline and Vernon units: Evangeline Unit This district features Kincaid Lake, Valentine Lake, and The Wild Azalea National Recreation Trail Other areas include the Kincaid Lake Day-Use Area, the Kincaid Lake Group-Use Area, the Valentine Lake Day-Use Areas, Valentine Lake Group-Use Area, the Bayou Boeuf Research Natural Area, and the Castor Creek Scenic Area.
