Beisiegel, B., Sana, D., & Moraes-Jr, E. A. (2012). The jaguar in the Atlantic Forest. Cat News Special Issue, 7, 14–18.
The causes of reduction of jaguars have not ceased since there is a continuous decrease in the Extent of Occurrence EOO, Area of Occupancy AOO and habitat quality, plus retaliatory and sport killing. The total number of mature individuals is less than 250 and the number of mature individuals is less than 50 in almost all subpopulations. The most serious threats to jaguars in the Atlantic Forest are habitat loss and degradation, loss of prey base and jaguar hunting. Legal protection has been ineffective.
