We are conducting surveys, monitoring, and research on cougars (puma, mountain lion) on the Ladder Ranch in south-central New Mexico. Here, cougars are of particular interest given their effects on state-endangered desert bighorn sheep and other valuable big game. These projects are also resources for training and education, most notably through the Cougar Field Workshop.

In our study of puma diet, we have discovered that pumas often provide valuable resources to a host of other species, including other predators such as these eagles and coyote. Omnivores, such as these ravens, as well as jays and javelina, have also been seen feasting on the leftovers. This young elk was killed in January by LM2, who uncharacteristically left it uncovered. This represents one of the many indirect effects top predators can have on ecosystems.
