Weaver hair-snaring surveys were conducted at 125 sites on 27 Refuge tracts to obtain information about the distribution and population status of the endangered ocelot ( Leopardus pardalis ) in the Lower Rio Grande Valley National Wildlife Refuge. The surveys resulted in 33.6% of the pads “hit”, including 8 by ocelot and 29 by bobcat. There was no significant difference in the number of ocelot hits between warm and cool seasons or between the sexes. Preferred habitat consists of dense thornscrub brush. Four species, snake-eyes, granjeno, honey mesquite, and colima comprise 50% or more of the total cover at each site where ocelots were detected. The ocelot sites averaged 146% total cover and 58.7% community similarity, as well as showing a significant interaction between the presence of snake eyes and colima with that of ocelot.
