Ulla Ulla National Reserve
From Wikipedia, the free encyclopedia
The Ulla Ulla National Reserve is a biosphere reserve located in the Franz Tamayo Province, in the Department of La Paz in western Bolivia.
The Reserve is on the high Andean plain northwest of the city of La Paz, with an average altitude of over 4000 meters about sea level. Its western border is the political border with Peru. The park is about 2,000 km² in size, is populated by about 12,000 people, most of them of Aymara origin, and is also the home of the Andean Condor (Vultur gryphus) (reportedly the largest flying bird in the world), as well as significant populations of llamas, alpacas, guanacos, and the largest group of vicuñas (Vicugna vicugna) in Bolivia.
The park was designated a UNESCO biosphere reserve in 1977.
