Prior to settlement, Monroe County was densely forested, with bayous, sloughs, and swamps crossing the land. Seeking to take advantage of the area's fertile soils, settlers cleared the land to better suit row crops. Although some swampland has been preserved in the conservation areas like the Cache River NWR and White River NWR, and some former farmland has undergone reforestation, the majority (52 percent) of the county remains in cultivation. Another large land use in Monroe County is the Cache River NWR and White River NWR, owned by the United States Fish and Wildlife Service.
