In Mexico, the tropical rain forest and the mesophilic mountain forest have been eliminated and fragmented, and in these ecosystems is where the ocelot (Leopardus pardalis), a species considered in danger of extinction in Mexico, lives. The objective of this work was to determine the changes in land use, fragmentation of primary vegetation and its effects on the ocelot, in a key area for the connectivity of their populations. To carry out this work, the rates of change in vegetation and land use were calculated, and a fragmentation analysis was carried out. For the registration of ocelots, trap cameras were placed in an area of 110 km2. The results showed a change rate of -2.63 and -2.29 for the tropical rain forest and the mountain mesophilic forest, respectively. Ocelot observations occurred inside or very close (1.6 km) to areas with a connectivity value > 10 %. The size of the habitat fragments was small: 0.85 ha for mountain mesophilic forest and 1.04 ha for tropical rain forest; and the connectivity between them was <30 %. These results reflect the need to keep landscape connectivity for the conservation of L. pardalis populations.
