Esperanza Ranch


Tucson Audubon is enhancing wildlife habitat along the lower Santa Cruz River in northern Santa Cruz County.The project site includes a riparian zone fed by a combination of natural flows and effluent from the Nogales International Wastewater Treatment Plant. Restoration focuses both on the hydroriparian vegetation along the river and on adjacent former farm fields and grazing land in the river's floodplain. Project personnel produced a site assessment and work plan, and have begun planting, seeding, and other work.

Esperanza Ranch is an area of sensitive habitat and is access is governed by a conservation easement agreement between Tucson Audubon and the landowner. You may not visit except during official Tucson Audubon events led by Tucson Audubon staff members.
