Provinces of Loreta, Requena, Ucayali and Alto Amazonas. It has a
surface area of 2,080,000 hectares and due to it's size
it is the largest in the country, the second largest in the Amazon,
and the fourth in South America. It's central position in the
Peruvian Amazon, as well as it's great expansion assure conservation
of representative samples of the tropical humid forests ecosystems
and supports investigations of the wild flora and fauna ( land and
The fauna of the reserve is abundant and diverse. The number of
mammal species reaches 132 species, those which stand out are the
rodents and monkeys. There are 330 bird species registered, 23 of
them are migratory, corresponding to 17% of all birds reported for
the country. The reptiles and amphibians are estimated to be more
than 150 species grouped into 20 families and they have reports of
the existence of 220 fish species.
The aquatic fauna is the most important resource of the
reserve, among the fish are the Pirarucu (Arapaima gigas),
known for their great size and quality of their meat. Also, found
