Evidence of Resident Jaguars (Panthera onca) in the Southwestern United States and the Implications for Conservation

  title={Evidence of Resident Jaguars (Panthera onca) in the Southwestern United States and the Implications for Conservation},
  author={Emil B. McCain and John Lewis Childs},
Abstract Jaguars (Panthera onca) remain virtually unstudied in the desert environments at the northern extent of their range. Historic sightings from the United States indicate a declining population of resident jaguars from the late 1800s into the 1940s, after which only occasional jaguars were reported until the present. After 2 sightings of jaguars in 1996, we established a camera monitoring program in southeastern Arizona. From March 2001 to July 2007, we maintained 9–44 trail cameras and…
