Jaguars are in critical situation in Brazil. We have found that the species have disappeared at the alarming rate of 1 degree of latitued every ten years during the last five decades from the Atlantic Rainforest of southern Brazil. See the original published article resulting from our research. That is the reason we launched Conservation Expeditions, to bring people from all over the world to help the species' conservation. Now the Amazon forest is under severe pressure from the construction of new highways that provide ease access to once remote places.
Jaguar Corridor project begun in 2006 with the participation of international
participants. Expeditions are conducted every year to map the current core
areas of distribution of jaguars and access their conservation status.
Since its conception, the project has produced several reports from data
collected with the help of participants that join us in the field (see latest report).
Projeto Puma has developed expeditions in two areas of the Atlantic Forest, and is now launching a new expedition to the Amazon forest.
The expedition to the Atlantic Forest is located in an area in which jaguars have now a low probability of survival in the long term. In fact, it is estimated that less than 250 jaguars live in this ecosystem. The Amazon is still a place where jaguars are relatively common, but this situation is changing rapidly. The Amazon expedition is located in an area in which jaguars still have a high probability of survival in the long term (see figure below).
