In the most threatened Brazilian biome, the Jaguar Conservation Fund supports camera traps research to obtain information about jaguar presence and absence in protected areas.

The Atlantic Forest is the most threatened biome in Brazil. It is one of the richest forests in the world, but actually only 7% of its original vegetation remains (Source: SOS Atlantic Forest). In this biome, the jaguar has lost much of its distribution and currently occurs in small and fragmented populations, suffering the threat of genetic isolation as well as decimation due to hunting and the reduction of their prey species.

The Jaguar Conservation Fund / Instituto Onça-Pintada is supporting research in different protected areas of the Atlantic Forest using camera traps. The main goal is to investigate jaguar distribution in this biome and to understand which factors influence the species. In Serra do Mar State Park, the largest protected area of the Atlantic Forest, two regions were sampled with the objective to estimate the mammals’ density and abundance as well as to understand the consequences of herivore mammal extinction on the flora or the biome. In Carlos Botelho State Park, a UNESCO World Natural Heritage Site, camera traps were used to verify the presence or absence of felids and large frugivorous seed dispersers. Although there were no jaguars recorded in the area, the presence of the species can not be discounted because there are rumors of jaguars in adjacent areas (Núcleo Cunha).
