Spring Restoration in Bear Canyon

Help us restore a wildlife oasis by removing invasive grasses and oleander along the Bear Canyon drainage around Rancho Fundoshi Spring. We’ll be working in the soil, bending, kneeling, and using hand tools, picks, and lots of elbow grease.

Spring Seeking in the Catalinas

February 26, 2026

Erosion control

Erosion Control in the Catalinas

February 24, 2026

Join us in the Santa Catalina Mountains for a weekend building erosion-control structures in areas burned by the 2020 Bighorn Fire. Together, we can protect springs from landslides and ensure the mountain absorbs even more rain and snowmelt, recharging the aquifer that plants, wildlife, and people like us depend on. Note: Carpooling from Tucson is available, and day-trippers are most welcome. We’ll be camping at Whitetail Campground on Mt. Lemmon.
