Ulistac Natural Area, Nature reserve in Santa Clara, United States.

Ulistac Natural Area is a 40-acre nature reserve in Santa Clara, the last undeveloped land in the city, where restored native California plants, grasslands and woodlands border the Guadalupe River. Walking trails and viewing spots let visitors watch the wildlife that has returned to these habitats.

This natural area was established in 2001 as the last undeveloped land remaining in Santa Clara. Its creation marked a turning point when the city shifted its focus toward protecting natural spaces within an urban landscape.

The name Ulistac comes from the Ohlone word for the area, and the site is used today for guided walks and volunteer restoration days. Local groups plant and tend native species such as yarrow and needlegrass, and visitors can join scheduled work sessions that show how the reserve is managed.

The site is open daily with walking trails suitable for different fitness levels and observation areas for wildlife viewing. Wearing comfortable shoes and bringing water is advisable, and early morning visits offer the best chance to observe animals in their natural behavior.

The jackrabbit is the detail to watch for: this species, along with butterflies, nesting birds and lizards, has returned to land that was once nearly bare of wildlife habitat. Restoration work by volunteers converted the former fields into the habitat these animals now use.
