 Some 40% of the area of Toro Negro State Forest is located in Ponce's Barrio Anón.When created in 1935 as part of the Caribbean National Forest, the Toro Negro Forest Reserve was managed by the United States government, first via the Puerto Rico Reconstruction Administration of the Department of the Interior (1935–1942) and later through the Forest Service of the Department of Agriculture (1942–1970).Then, in 1970, the Federal Government exchanged with the Government of the Commonwealth of Puerto Rico the Toro Negro section of the Caribbean National Forest for some forested lands belonging to the Commonwealth and located adjacent to the much larger federal lands at Luquillo National Forest resulting in the creation at Luquillo of the current El Yunque National Forest.
