text: Mantadia National Park is missing on the map.
  
  Mantadia National Park and Analamazoatra together form the Andasibe-Mantadia National Park, see https://en.wikipedia.org/wiki/Andasibe-Mantadia_National_Park
  
  However, Mantadia National Park alone still exists officially, according to http://www.parcs-madagascar.com/
  
  So I guess the best option is
  - add Mantadia National Park
  - set up a relation containing Mantadia National Park and Analamazoatra to form Andasibe-Mantadia National Park
