SIA’s Ranchos Regenerativos tech Karen Aglaee Lopez Roman will also be there tabling, so stop by and say hello.

Ocelot

Coffee Break: Himdam, the Remarkable Ocelot That Traversed 4 Sky Islands

April 14, 2026

Join us for this virtual Coffee Break to learn more about the remarkable journey of a male ocelot across four mountain ranges in the Sky Islands of Arizona, the longest-known trek by a single member of the species. This ocelot covered at least 111 miles and crossed I-19, AZ-82, and AZ-83 (at least twice) as it moved among the Atascosa Highlands, Whetstone Mountains, Patagonia Mountains, and Santa Rita Mountains. One of the more fascinating aspects of this story is that the ocelot was detected in four separate ranges by four organizations, who then collaborated to tell the story. We’ll be joined by several partners for the talk to discuss this intrepid cat and what’s next for ocelot conservation.
