Jaguars get new layer of U.S. protection with Critical Habitat designation.

Ocelots and jaguars are once again calling the Sky Islands their home... or have they been here all along? 

Throughout the majority of the last 17 years at least one jaguar has been present in the Arizona/Sonora borderlands, and as many as 8 different individuals have been photographed during this time. SIA documented the first living record of an ocelot in Arizona in 2009 - and a short time later recorded the first evidence of ocelots breeding in the Sky Islands, with a kitten and mother filmed on camera in Sonora, Mexico.

To help these elusive and secretive wild cats stay and thrive, Sky Island Alliance is advocating for jaguar and ocelot conservation in the region: by promoting greater public understanding of the importance of carnivores; informing critical habitat designation; identifying and mapping their best habitat and movement corridors; analyzing motion-activated camera data to determine wild cat activity patterns and behavior; and supporting non-invasive wildlife monitoring.

Do you want to learn more about jaguars and ocelots in the region? Read Sky Island Alliance's peer-reviewed paper, "Wildlife Survey and Monitoring in the Sky Island Region with an Emphasis on Neotropical Felids," published in the proceedings of the 2012 Madrean Conference.

Protecting these spotted cats also helps us explore and protect other critters too! See photos and videos of more wildlife from our motion-activated cameras.

Knowing that jaguars and ocelots are present in our Sky Island region is one of the reasons we are passionate about what we do. Please help us continue this important work.
