Festival por los Pastizales
May 4, 2026Come enjoy a weekend with us from May 29–31 in Cananea, Sonora. This is an opportunity to celebrate with the community at the Festival for the Grasslands of Northeast Sonora — a space designed for sharing, learning, and coming together. Cananea lies at the heart of the Sky Islands region, a place of rich biodiversity where rivers are born and culture thrives. This gathering is part of the celebration of the International Year of Rangelands and Pastoralists (2026), championed by the Food and Agriculture Organization of the United Nations, which seeks to recognize the importance of grasslands, biodiversity conservation, and the livelihoods of rural communities. Save the date — more details coming soon!

Coffee Break: Himdam, the Remarkable Ocelot That Traversed 4 Sky Islands
April 14, 2026Join 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.
Spring Restoration in Bear Canyon
