The jaguar is the top predator of the Atlantic Forest (AF), which is a highly threatened biodiversity
hotspot that occurs in Brazil, Paraguay and Argentina. By combining data sets from 14 research groups
across the region, we determine the population status of the jaguar and propose a spatial prioritization
for conservation actions. About 85% of the jaguar’s habitat in the AF has been lost and only 7% remains
in good condition. Jaguars persist in around 2.8% of the region, and live in very low densities in most of
the areas. The population of jaguars in the AF is probably lower than 300 individuals scattered in small
sub-populations. We identified seven Jaguar Conservation Units (JCUs) and seven potential JCUs, and
only three of these areas may have ≥50 individuals. A connectivity analysis shows that most of the
JCUs are isolated. Habitat loss and fragmentation were the major causes for jaguar decline, but human
induced mortality is the main threat for the remaining population. We classified areas according to their
contribution to jaguar conservation and we recommend management actions for each of them. The
methodology in this study could be used for conservation planning of other carnivore species.
