Rangeland Resilience – Here, There, and Yonder

In celebration of 110 years of the Sonora Research Station and in recognition of the International Year of Rangelands and Pastoralists, we invite you to join us for a special day of learning, connection, and discovery.

This milestone event will feature a mix of informative talks, guided tours, and hands-on exhibits exploring the past, present, and future of rangeland ecology and management.

After a welcome session and an update on new world screwworm, participants can explore a wide range of topics - from current livestock and wildlife management issues to predation management, prescribed fire, soil macro-organism webs, avian ecology, and the uses of medicinal and edible native plants.

With a "county fair" atmosphere, guests can enjoy a variety of engaging booths, local exhibits, and family-friendly activities throughout the day.

Whether you’re a rancher, researcher, student, or member of the community, you’ll find inspiration in the stories, science, and shared stewardship that define rangeland resilience - here, there, and yonder.

Join us for a day celebrating community, science, and stories from the range.
