| Red List assessment for the jaguar in the Caatinga Biome | |
| 2012 Cat News (Special Issue 7): 19-24 | |
The Caatinga is the only exclusive Brazilian Biome and the jaguar _Panthera onca _is one of the most endangered species in this biome. In this paper we present the status of the species in the Caatinga biome. No specific information on jaguars' biology and ecology is available for the Caatinga. Jaguars are distributed within the Caatinga along 178,579 km2, which represents 21% of the biome. This range was estimated based on the confirmed locations, population ranges, and the favourable areas for its presence based on habitat viability models. It seems that the jaguar population in the biome is very fragmented. Five sub-populations were identified and the area of occupancy of jaguars was 87,325.50 km2. This area comprises only 10% of the total area of the Caatinga biome. The general average of all the density estimates resulted in a number of 0.3 individuals/100 km2, a very low population with estimation of 262 individuals. The status of conservation of jaguar is Critically Endangered C2 a(i). Among the main threats to its populations are stern fragmentation, habitat loss and degradation, loss of prey base, jaguar hunting, and industrialization of the surrounding areas. Some conservations measures like maintenance of the gene flow among jaguar populations by means of ecological corridors and a new protected area are urgent actions. |
