Office of International Affairs - Program Topics

In a 1916 letter from Interior Secretary Franklin K. Lane to first NPS Director Stephan Mather, the Service was directed to maintain contacts with national park authorities in other nations and to stay informed on their developments in order to identify areas for improvements in the U.S. National Park System.
Since that time, the National Park Service International Program has continued to promote and facilitate collaboration in perserving and understanding natural and cultural heritage throughout the world.
Sharing expertise with visiting park and conservation professionals, in addition to the National Park Service’s overseas technical missions, demonstrates the full-range commitment of the Park Service in its contributions to global environmental conservation.

The United States established Yellowstone as a national park in 1872 and initiated the worldwide movement to protect such areas as national treasures. One hundred years later, during the Nixon administration, the United States proposed the World Heritage Convention to the international community and was the first nation to ratify it. The World Heritage Convention, the most widely accepted international conservation treaty in human history, is the American national park idea being carried out worldwide. |
