Pacaya Samiria National Reserve the Amazon - Peru
It was established in the 1940s to protect the largest fresh-water fish, the paiche, Pacaya-Samiria National Reserve now protects the entire Pacaya-Samiria watershed, it's the largest protected area in Peru. Pacaya-Samiria accounts for almost 2 percent of Peru’s land area. It is home to over 100,000 people within its boundaries and over 600,000 people in nearby areas use its resources.
As the largest tract of flooded forest in the Amazon, the reserve offers a wealth of resources to the area’s human population. Most of the reserve’s large human population practice subsistence lifestyles and depend as much on the preservation of Pacaya-Samiria’s resources as the threatened wildlife.
The Pacaya-Samiria Reserve is Unique
This Reserve is like no other protected area in Peru as it is directly linked to the economic well-being of such a large number of people. At least 100,000 “ribereños,” people

More than 5 million acres
Pacaya is the second largest national reserve in Peru, spanning more than 5 million acres. It is also the largest protected flooded forest in the world, making it one of the prime intact swaths of rain forest in the Peruvian Amazon.

Location - the headwaters of the Amazon - Peru
Pacaya Samiria is located in the headwaters of the Amazon River in the northeastern Peru, on an alluvial plain between the Marañon and Ucayali river systems. The reserve is accessible via the Amazon River through the nearby city of Iquitos in the department of Loreto, or through the city of Tarapoto in the department of San Martin.

Flora and Fauna
Nearly 1,000 plant species grouped into 132 families have been documented in Pacaya, including 22 species of orchids and 29 species of palms.


The aguaje fruit is critical to the diets of parrots and mammals such as the tapir, paca and agouti, while people use the fruit in drinks and ice cream. Birds and mammals feed on the fruit of the chonta palm, while humans harvest the palm’s heart.
Why conservation works Here
Widespread human migration into the Amazon since the 1970s has eliminated key forest tracts and fractured others. Uncontrolled hunting, logging and unsustainable fishing and harvesting of forest products further threaten Pacaya Samiria and its surrounding lands and waters. Give its extent, location and high biological diversity, Pacaya is a priority conservation site. Its conservation and management are key for sustaining the long-term well-being of its inhabitants.
