Your help is needed to stop invasive arundo from spreading downstream, where it could eventually reach Sabino Creek.

Tucson ‘Spring Cleaning’

March 7, 2025

Join our campaign to remove invasive species at nine priority springs in the Tucson area. Together, we can restore these crucial wildlife oases! We’ll meet every Tuesday morning and be working mostly in the Sabino Canyon area on the northeast side of town and near Vail and Davidson Canyon on the southeast side. Stay as long as you like, and leave for work if you need to. This is a great way to create an impact, get in a workout, and meet other volunteers.
