It is situated in the department of Puno, provinces of Huancané and Puno. It has an area of 36 180 hectares including two sectors: the Ramis sector in the Huancané province (7,030 hectares), and the Puno sector in the province of Puno (29,150 hectares).
The most attractive fauna in the area is made up of migratory and resident birds. There are more than 60 species, the most outstanding being the Titicaca flightless grebe (Centropelma micropterum), the Puna Ibis (Plegadis ridgwayi), the white-creasted Cormorant (Phalacrocorax olivaceus), and the wren-like rushbird (Phleocryptes melanops).Among the resident families we can find ducks (Anatidae) and rails (Rallidae), whereas the migratory families include plovers (Charadriidae), waders (Scolopacidae) and flamingos (Phoenicopte-ridae).
Only few mammal species live in the reserve, predominantly rodents such as the Peruvian mountain vizcacha (Lagidium peruanum), the wild guinea pig (Cavia tschudii) and the Andean fox (Pseudalopex culpaeus).Being one of the main elements of the ecosystem cycle, the vegetation in the lake has been classified as amphibious, submerged and floating. Its flora consists of 12 varieties of aquatic plants, such as the reed plant or cattail (Schoenoplectus totora), the pondweed or yana llacho (Elodea potamogeton), the duckweed (Lemna sp.), and the muskgrass (Chara sp).
The reserve has also more than 64 genuses of riverside flora.The main objectives of the Titicaca National Reserve are to conserve its flora, fauna, and beautiful sceneries; to preserve natural resources such as the reed plant or cattail, which is home to a great diversity of species; to support the socio-economic development of the surrounding villages through the rational use of wildlife; and to promote local tourism without disturbing the cultural traditions of people inhabiting this area.
