Explore the Watershed: New Trail Map Available!

Scan QR codes at trailheads or explore the webpage from home

We’re excited to share that we’ve published a digital trail map on our website! The webpage highlights select trails throughout the Sausal Creek Watershed, providing helpful information such as trail descriptions, length, accessibility, and parking.


For easy access while you’re out exploring the watershed, we’ve posted QR codes at key trailheads including Upper Fern Ravine, El Centro, and Bridgeview, just to name a few. We plan to expand these signs to more locations in the future.


A small reprint of updated physical trail maps is also coming this fall, which will be available in map boxes across the watershed.

Friend of the Month

David Moore

Meet David Moore, an urban forestry leader who spent seven years overseeing the City of Oakland's Parks and Tree Services Team—and became one of FOSC's most valued partners along the way. We'll miss working with David in Oakland, but we're thrilled to see him take on a new challenge leading San Francisco's Bureau of Urban Forestry.

Oakland High School Restoration Project

Student-Created Short Video

This spring, eleventh graders in the Environmental Science Academy Pathway at Oakland High School chose restoration at Dimond Park as their annual project. Over the course of six weeks, 18 students committed to removing invasive plants for an hour each Monday through the end of the school year. Their consistent effort paid off—they cleared more than 17 cubic yards of English ivy, Cape ivy, Himalayan blackberry, foxtails, French broom, and poison hemlock from their restoration site. Shoutout to a student participant for this great video!

A New Addition to the Sausal Creek Watershed Plant List

Eucrypta chrysanthemifolia - Spotted Hideseed

During a recent walk on the Bridgeview Trail, FOSC Board President Robert Leidy spotted a plant he didn’t recognize—later identified as spotted hideseed (Eucrypta chrysanthemifolia var. chrysanthemifolia), a native annual not previously reported in the Sausal Creek Watershed. This California-endemic species is typically found in open woodlands, chaparral, and other habitats, especially after fire. Look for its small white, purple-veined flowers between March and June!
