Ben En National Park was established under Decision No. 33/CT dated 27th of January in 1992 of the Chairman of the Council of Ministers of Vietnam (now Prime Minister). In the past the forests around Lake Song Muc were subject to economic exploitation. To protect the rich biodiversity in 1986 the area was converted to Ben En Nature Reserve. The Ministry of Agriculture and Rural Development (MARD) finally gave Ben En the status of a national park. Since 2008 Ben En is under management of Forest Protection Department Thanh Hoa.
