. Some of the forest is reclaimed farmland, but much of it was never farmed because of the steepness of the terrain.

The State and the various Federal agencies actively cooperate in the management of the lands under their care, particularly in the use of fire to maintain goat prairie

, the first sawmill in Iowa was also located in Yellow River, which was built in the 1800's. About 150,000 board feet (350 m³) lumber of is annually harvested in the forest and processed by inmates at the minimum-security Luster Heights Prison Farm

. The prisoners do other work in the forest as well. The lumber produced at the sawmill is used for state-related projects and can be produced for private orders. The type of wood produced at the sawmill depends on the type of wood that grows in the forest (mainly oak and hickory).

Yellow River Fire Tower

The forest includes the Yellow River Fire Tower, the only fire tower standing in Iowa. The tower is an Aermotor LS40 model fire tower
sold to the Iowa Department of Natural Resources from the U.S. Forest Service. It was acquired in 1950 and rebuilt on the current site in 1962. Today it is in poor condition, most of the window sashes have been broken out, all the window glass is gone, some of the cab roofing is gone, and the wood on the stairs and in the cab has rotted away, most of this is due to vandalism. So for that and safety reasons, the tower was fenced in and is currently closed to the public.
