 In 1970, the Government of Puerto Rico's Departmento de Recursos Naturales y Ambientales (DRNA) opened the Toro Negro Forest Reserve as a Commonwealth state forest and renamed it "Bosque Estatal de Toro Negro" (Toro Negro State Forest).In 1876, Spanish King Alfonso XII of Spain issued the first proclamation for the creation of forest reserves in Puerto Rico.The land where Toro Negro sits was originally used for coffee plantations until the 1930s when a program of reforestation was commenced.
