John Terborgh, in his book Diversity and the Tropical Rain Forest, calculates that a viable population of jaguars (about 300 breeding adults) needs about 3,000 square miles [7,500 sq km].
John Terborgh toob oma raamatus ” Diversity and the Tropical Rain Forest ” ära arvestuse, mille kohaselt elujõuline jaaguaride populatsioon (umbes 300 suguküpset isendit) vajab umbes 7500 ruutkilomeetri suurust territooriumi.
