The International Coordination Council of the UNESCO Program “Man and Biosphere” (MAB) met for the first time in 1971, and the concept of Biosphere Reservation emerged in 1974. The program to create a world-wide network of biosphere reserves Was launched two years after the concept proposal. In 1995 the Seville Conference defined for the first time a strategy and developed a statutory framework that supports accepted principles by all states. In the same year, the UNESCO General Conference adopted the Seville Strategy and Framework. In 1932, 183 hectares of alpine hole in the Pietrosu Mare Peak area (2,303 meters) were declared scientific reserve, being the first such reservation in Romania. The importance of the area, but also its beauty, made the protected area later extended to 3,300 hectares. At present there are four scientific reserves in the Rodna Mountains National Park (Pietrosu Mare – 3,547.6 hectares, Piatra Rea – 291 hectares, Corongiş – 614.9 hectares and Bila-Lala – 1.318.2 hectares), plus six reserves (100 hectares), Izhaarele Mihăiesei (61 hectares), Valea Cormaia (50 hectares), Saca Massif (7,8 hectares), Cobăşel Cave (one hectare) and Natural Reserve Izvorul Bătrâna (0.5 hectare). . Over 2,300 hectares of the Rodna Mountains National Park are declared a strictly protected area because of protected areas of great scientific importance, including wild areas where human intervention was extremely low. It is forbidden to carry out any human activities, except for research, education and ecotourism, but also any activity of exploiting natural resources.
