The distribution of ocelots Leopardus pardalis in the USA is limited to southern Texas. Identification and monitoring of ocelot populations enables biologists to assess population health and status. Use of camera traps has been successfully used to monitor numerous populations of wild felids, including the ocelot. Our objectives were to identify ocelot presence within southern Texas and estimate ocelot population size and density. We used camera traps to survey for ocelots on four study sites in southern Texas. We recorded ocelot presence on one study site with an abundance estimate of three individuals and a density estimate of 0.30±SE 0.03 ocelots km−2. The conservation implications of this study suggest concentrating conservation efforts in and around the study site (Yturria Ranch) found to have ocelots. In addition, this study emphasizes the importance of including private landowners in the ocelot recovery process.
