Events for April 23, 2026
Binational Border BioBlitz
Calling birders, botanists, bug lovers, trackers, herpers, fungi folk, and naturalists of all sorts! Join SIA and partners for a special binational event, starting at Cuenca Los Ojos ranch in Sonora. Groups will be surveying on both sides and will eventually meet at the wall. If you'd like to join from Arizona instead, see the event on April 25.
Workshop: Springs Trip Planning and Navigation
Join SIA staff for an evening at our Tucson office getting ready for upcoming volunteer trips to visit springs within the Sky Islands. Topics covered will include: reading maps and satellite images, navigation aids on desktop computers and smartphones, making tracks and reading elevations and contours on maps, planning backcountry vs. trail walks, etc. With these skills, you’ll be ready to volunteer with confidence.
