World War II. Camp Claiborne was the largest
military installation in the United States and the third largest city in Louisiana. Today, part of the old camp is used as a
U.S. Air Force bombing range.

Other notable activities in the area include Cooter's Bog Special Interest Area, Drake's Creek Special Interest Area, Quiska Chitto Special Interest Area, and the Longleaf Scenic Area. Animals in the area include the
red-cockaded woodpecker (
Picoides borealis). The red-cockaded woodpecker, often referred to as the RCW, is one of the few birds endemic to the United States and many colonies are in the Vernon Unit. The RCW only nest in cavities of specific trees. Having extremely specific habitat requirements lost by mass deforestation caused large population declines and the extinction of numerous colonies in the 20th century. It was listed as a
Federal Endangered Species. All areas in this unit where RCW reside have been identified and are distinctly marked. The markings include a boundary of Department of Forestry Service signs and white paint markings on the boundary trees. Many of these habitats can be observed from the roadside of La-Forestry Rd. 410, known as Bailey Road, that runs from
Rosepine to
LA 10. The Louisiana Statewide Red-cockaded Woodpecker Safe Harbor Program is a partnership between the Louisiana Department of Wildlife and Fisheries and the
U.S. Fish and Wildlife Service to enlist the aid of non-federal property owners to help build and maintain adequate foraging habitat. The
wild turkey was a very important food animal to Native Americans, but it was eliminated from much of its range by the early 20th century. Large groups of these birds can be observed on or near LA-Forestry rds 430 (Marlow Road) and 431 (Drakes Fork Road) that is off LA 10 just west of Cravens. The Calcasieu's Vernon Unit is frequently used by neighboring
Fort Johnson for training and the military leases training access to many areas. Areas affected by military operations will be posted by Fort Johnson and Kisatchie. ==Caney Ranger District==
