A concern around the turn of the 20th century was that many woodworking facilities in Indiana would be forced to close due to dwindling timber supplies. This wood was used by furniture makers and shipbuilders such as the Howard Shipyards. The timber industry was a major part of southern Indiana's agricultural income, but thousands of acres had been deforested. In response to the problem, the state of Indiana decided to establish a series of state forests to ensure the continued existence of timber for woodworking facilities, and to allow Indiana to maintain its ability to export hardwood. The Indiana General Assembly in 1901 created the Indiana State Board of Forestry. In May 1903, the Indiana state government purchased of forest in the north of Clark County, noted for its knob features, for use as Indiana's first state forest, at a cost of US$16,000. Seedlings were planted at Clark State Forest, many of which were to be later moved to other parts of the state. This practice allowed more productive use of the land within the forest, and facilitated the teaching of the art of forestry. Charles C. Deam, a botanist who in 1909 became Indiana's state forester, was in charge of making the state forest an experimental laboratory for 20th-century forest care. Between the opening of the forest, and 1935, over 150 different tree types were tested, many of which survive yet. During the Great Depression, the Works Progress Administration chose to make Clark State Forest a training center for the Civilian Conservation Corps, and also made it Indiana's largest CCC cantonment in November 1933. They created artificial lakes within Clark State Forest, and built many bridges, to aid in water conservation, provide beauty spots within the forest, and teach forestry skills to members of the Civilian Conservation Corps. The state forest's proximity to the Jeffersonville Quartermaster Depot was key in the decision to focus so much attention on it.
Features
Having grown from its original, Clark State Forest now covers, with many roads and paths. The area also includes of horse trails, ranging from "easy" to "rugged". The existence of these horse trails is one reason why nearby Charlestown State Park did not include them in its development plans. Hunting is allowed, except in those areas designated specifically for more popular recreational activities. Species of wildlife of interest to hunters include deer, foxes, ruffed grouse, squirrels, wild turkeys, raccoons and woodcocks. All the campsites are by design primitive, and the only other areas in the forest that are allowed for camping are off the Knobstone Trail. Other recreational pursuits for visitors include hiking, biking, fishing and picnicking. All of these human activities are however of secondary importance to the primary function of the state forest, which is timber management. Both native and non-native tree saplings are grown within the forest. Trees officially allowed to be sold for lumber within the state forest are between 70 and 100 years old. Often, the chosen trees are felled to provide an area for native deer to live in the open, and to give smaller animals a brush area for their subsistence. Included in some protected areas are the White Oak and the Chestnut Oak/Virginia Pine Nature Preserves. Other species of tree include black oak, black walnut, pignut hickory, sugar maples, and tulip trees. North of the Schlamm Lake is a fish hatchery. The lakes of Clark State Forest include:
