More than 2,500 river turtles return to Manuripi in a scientific crusade to save the Amazon

The Amazonian University of Pando led the release of baby turtles after a process of incubation and protection lasting nearly a year inside the natural reserve.

The Manuripi River basin once again became the setting for one of the most important conservation actions in Bolivia’s northern Amazon. The Amazonian University of Pando (UAP), through its Biology program, spearheaded the second edition of the River Turtle Conservation and Repopulation Program, achieving the release of more than 2,500 freshwater baby river turtles in different sectors of this natural reserve.

The activity not only symbolizes the return of thousands of specimens to their habitat, but also represents nearly a year of scientific work in an attempt to reverse the decline of a species facing growing threats from egg predation, the illegal capture of reproductive females, and the effects of climate change on Amazonian bodies of water.

The process began with the monitoring of natural beaches and the collection of eggs in vulnerable areas of the basin. These were later transferred to an artificial mother beach installed at the San Silvestre control post, inside the Manuripi Amazonian National Wildlife Reserve, where they remained under technical protection during 78 days of incubation.

Out of approximately 2,700 eggs collected, 2,526 managed to hatch successfully, a rate considered highly favorable for wildlife repopulation programs. The hatchlings were then kept for seven months in artificial ponds to strengthen their development before being returned to the river.

A key species for the ecosystem’s balance

The river turtle, scientifically known as Podocnemis unifilis, is a freshwater turtle native to the Amazon basin and fulfills an essential function in ecological balance: it disperses seeds, controls certain aquatic organisms, and forms part of the food chain of wetlands and riverbanks.

However, in Bolivia its populations have declined in recent years mainly due to the indiscriminate extraction of eggs for consumption, illegal commercialization, and the progressive loss of natural beaches suitable for nesting.

For this reason, environmental institutions have begun treating this species as a conservation priority. In the Manuripi Reserve—one of the country’s most biodiverse protected areas, with more than 747,000 hectares of humid Amazonian forest—one of the main natural laboratories for its recovery has been established.

University, park rangers, and local communities: an alliance gaining ground

Unlike other occasional release campaigns, the program developed in Pando has begun to show interinstitutional continuity. The UAP carried out the project with support from the San Silvestre community members, Fundación Semilla, the municipality of Filadelfia, park rangers, and technicians from the National Service of Protected Areas (Sernap), in addition to the reserve’s management committee.

The participation of the riverside communities has been decisive, because they are the ones who identify nesting beaches, report risks, and collaborate in safeguarding the eggs from looters or natural predators.

This is no minor detail: in a region where pressure on natural resources is growing due to extractive activities and wildlife trafficking, conservation is only viable if it incorporates community surveillance and environmental education.

A repopulation model beginning to consolidate

The release carried out this year is the second consecutive one under the interinstitutional agreement and confirms that the northern Amazon is building a sustained wildlife recovery strategy.

In 2024, the release of some 2,500 baby turtles had already been achieved, and in 2025 the figure surpassed 2,800, which shows an improvement in incubation, handling, and early survival processes.

Specialists believe that this type of program does not generate immediate results in population terms, but it does open a window for medium-term recovery, especially when it is ensured that the hatchlings reach sizes that reduce their vulnerability to predatory fish, birds, and reptiles.

The bet, at its core, is simple but urgent: to return life to Amazonian rivers before one of their most emblematic species disappears silently.
