The forest is extremely well preserved, and is home to the largest population of
jaguars (
Panthera onca) in the Atlantic Forest. It includes other threatened species such as
cougar (
Puma concolor),
South American tapir (
Tapirus terrestris),
bush dog (
Speothos venaticus),
pygmy brocket (
Mazama nana) and
southern muriqui (
Brachyteles arachnoides). The connection between the various areas in the Paranapiacaba mosaic will help the species to survive. The jaguar tends to avoid areas frequented by man, which include areas used by hunters and gatherers of heart of palm in the reserve. It is estimated that there are just 250 individual jaguars in the states of Paraná, São Paulo and Rio de Janeiro, most of them in the mosaic area. There are more than 450 species of birds. The country people of the region consider that the primates in the park are good to eat. In 2012 environmental police seized the bodies of two
howler monkeys and one southern muriqui. The muriqui, the largest primate in the Americas, is strongly threatened with extinction. In March 2013 environmental police found a hunter's camp with a shack equipped with a stove and kitchen utensils. A monkey that had been cleaned and was ready to eat was found, and the carcasses of an armadillo, and threatened birds such as
solitary tinamou (
Tinamus solitarius),
neotropical bellbird and
toucans. The hunters escaped into the forest. ==Notes==
