A national nature reserve, in French réserve naturelle nationale, (RNN) is a protected area that is part of natural reserves of France (RNF) and whose status is defined by the law on local democracy of February 27, 2002.
It is a tool for the long-term protection of spaces, species or geological objects.
[3] In 1961, the first RNN created is Lake Luitel in Isère.
[2] The Law n° 57-740 of July 1, 1957 amended the Law of May 2, 1930 by adding an article 8 bis allowing the classification of a site as a "nature reserve".
[5] Afterwards, the law on local democracy of February 27, 2002 redefined their status[6] by distinguishing between: National nature reserves are classified by ministerial decree or by decree in the Council of State.
