Onçafari Ecotourism works to habituate wild animals, such as jaguars and maned wolves, to the presence of our team’s vehicles. As the animals stop running away from our vehicles, researchers and visitors are no longer perceived as a threat, thus enabling the evolution of ecotourism in the region. Animal habituation does not mean domestication, but rather keeping them completely wild and free, without feeling threatened by the presence of vehicles. This habituation process is developed with the help of Cenap (National Research Center for Carnivore Conservation) an agency within the Chico Mendes Institute for Biodiversity Conservation, within the Ministry for Environment.


The goal of Onçafari Science is to monitor the health of the animals protected by the project, in addition to understanding their behavior, physiology, and ecology to increase the scientific knowledge about their species and maximize their protection. :

  • Our main lines of work include:
  • Animal monitoring using tracking techniques and direct observation.
  • Animal monitoring using motion activated cameras.
  • Temporary capture of animals of interest to the project to collect biological samples (blood, urine, fur, etc.) and, in some cases, place GPS radio tracking collars to map their location and consequently observe their behaviors.
  • Sending biological samples to the National Research Center for Carnivore Conservation (Cenap – ICMBio) genome bank for genetic studies and data storage for future research.
  • Development of studies on how to prevent conflict between jaguars and livestock in regions where the species coexists.


Onçafari Rewild reintroduces rescued jaguar cubs into their natural habitat.

Isa e Fera Jaguar sisters Isa and Fera were our first success story. They lost their mother when they were still cubs and were reintroduced into the Pantanal. After a careful adaptation process, they no longer needed support to live in the wild. They were integrated into the local jaguar population and now live peacefully in their natural habitat.
