| The status of the jaguar in the Pantanal | |
| 2012 Cat News (Special Issue 7): 29-34 | |
The Pantanal is considered an important area for the conservation of jaguars _Panthera onca _in the long-term. In comparison to other biomes in Brazil, the Pantanal can be considered still relatively well preserved. According to a recent study, the original vegetation cover remains intact in 85% of the Pantanal plain. However, in the uplands of the Upper Paraguay watershed over 50% of the original vegetation has been altered. This situation is worrisome as this area harbors the headwaters of the rivers that are responsible for maintaining the wet and dry cycles of the Pantanal. As opposed to previously reported, only about 63% of the Pantanal biome is actually occupied by jaguars. Habitat fragmentation caused by human presence and intensification of land use is a threat to jaguars in the Pantanal. Other threats include high levels of retaliation from ranchers due to livestock depredation and the lack of enforcement by wildlife authorities, illegal hunting tourism activity, pasture management through the use of annual fires, and the mining industry. The first estimate of a jaguar population in Brazil was conducted in the southern Pantanal (6.5-7.0 jaguars/ km2), although the distribution of the species is heterogeneous, which precludes an accurate estimation of the current population size in this biome. Authorities should recognize the cost associated with grazing cattle in an area where jaguars exist in considerable numbers and regularly prey on cattle. A unique regional policy could address some of the problem, perhaps in the form of tax benefits, special lines of credit, or a regional increase in beef prices. It is important that environmental actions be implemented to increase market value of cattle raised in the region without changing the main characteristics of the Pantanal. |
