Today, about 90 percent of the jaguar population is found in the Amazon region, mostly in Brazil. The Pantanal region in Brazil, Bolivia and Paraguay has one of the areas with the highest density of jaguars in the world—an estimated 6.7 jaguars per 100 square kilometers. Although this number is high, it is important to acknowledge that many of the healthy and stable jaguar populations are constrained to micro territories. Human development has restricted the range of the jaguar and the size of its territories.
