As part of the Desert Foothills Land Trust’s mission to connect people and nature, DFLT sponsors two Speaker Series — ongoing free lecture programs designed to connect community members with the natural and cultural heritage of their Sonoran Desert home. These lectures provide accessible educational opportunities for everyone to deepen their understanding of this unique desert ecosystem. The Foothills Speaker Series is a joint initiative of DFLT and the Holland Center. Click here to see all this season’s (2026-2027) events in the Foothills Speaker Series.
