Our Work


Onçafari Rewild was structured in partnership with CENAP and ICMBio. The object of these research projects was to reintroduce jaguars into their natural habitat, an important tool for the recovery of endangered populations.

Currently, Onçafari rehabilitates small, medium and large mammals for later release into the wild. We have an area with two enclosures dedicated to rehabilitation and release into our bases in the Pantanal and the Amazon.

Isa and Fera

The first successful case was that of the sisters, Isa (pictured below) and Fera (pictured above), jaguars who lost their mother at a young age and were successfully reintroduced into the Pantanal. After careful adaptation, they did not require support when they returned to nature: they integrated into the population of jaguars in the region and now live normally in their natural habitat. The success of this project was confirmed in 2018 with the birth of cubs from the two free-living jaguars.

Main steps to reintroduction

Jaguar health and behavior are evaluated and a study conducted to determine the feasibility of reintroduction to life in the wild.
The animals are introduced to an enclosed area similar to their natural habitat, where they can learn to hunt. They are observed and assessed by the Onçafari team and partners.
When they are deemed ready to be reintroduced into the wild, GPS radio tracking collars are fitted on the animals for round-the-clock monitoring after their release.
Jaguars are monitored to assess whether they are capable of dealing with all challenges imposed by nature. If necessary, they are rescued again for aid.
