Gabon is also noted for efforts to preserve the natural environment. In 2002, President Omar Bongo Ondimba designated roughly 10% of the nation's territory to be part of its national park system (with 13 parks in total), one of the largest proportions of nature parkland in the world. The National Agency for National Parks manages Gabon's national park system. Gabon had a 2018 Forest Landscape Integrity Index mean score of 9.07/10, ranking it 9th globally out of 172 countries.
