ResumoThe Province of Oxapampa – Pasco has four Protected Natural Areas; in three we are developing the project Floristic Diversity of the Natural Area Protected and Adjacent Areas in the Center and the South of Peru. The Natural Areas Protected that includes our project are: The National Park Yanachaga – Chemillen National Park (122.000 hectares), Protected Forest of San Matias San Carlos, (145.818 hectares) and the Yanesha Communal Reserve, (34.744,70 hectares). The study is located in an isolated mountainous chain and includes territories located in the eastern slopes of the Andes and comprises of the Amazon river basin; including five physiographic regions of the country with mountains, high and low forest. According to some authors the zone is within the Pleistocene Refuge PachiteaUcayali. In its interior four types of climate, four edaphic regions and seven life zones of life have been recognized; that go from the Tropical Humid Forest (bh-T) to 300 m, towards the east in the Amazonian plain; until the Pluvial Forest Tropical Montano (bp-TM), to ca. 3800 ms, in summits of the Yanachaga mountain. Our database contains 16376 botanical collections, of which, only 6911 have been examined, resulting in 2701 species, distributed in 882 genera and 181 families being Angiosperms. The 15 families with greatest number of species and contributing ca. 50 % of the current known flora: Fabaceae, Melastomataceae, Poaceae, Rubiaceae, Asteraceae, Orchidaceae, Solanaceae, Araceae, Piperaceae, Bignoniaceae, Moraceae, Arecaceae, Acanthaceae, Cyperaceae and Lauraceae. We consider this species number low due to the great diversity of habitat, altitudes and soils. The total number of species recorded may reach 5000 species of vascular plants.
