Abstract: This study consisted in the application of GARP in modeling the potential habitat of the maned wolf. The main objective was to know the consequences of the actual habitat fragmentation for this species. To build the models, 39 surveys with occurrence of the maned wolf were compiled and the following digital maps were used: temperature, precipitation, elevation data and NDVI of 1995 and 2000. Current models from 1995 show an expansion of the potential distribution area and the were more concentrated in the central-western and south-eastern regions of Brazil. The resulting model for the year 2000 shows a potential expansion of wolf life area for the north of Brazil. Models using data from 2000 present a greater fragmentation and an overall reduction of the potential area. Southeast of Brazil becomes an important area for future conservation of the maned wolf and the São Paulo State with only 0.95% of the original Cerrado areas still remain. This fact can have serious impacts on the geographic distribution and on the genetic variability of maned wolf populations.
