Join Rivers & Lands Conservancy for our annual acorn harvest at Cienega Canyon Preserve! Over the past decade, many of the preserve's oaks have suffered from drought, pests, and disease, leading to a significant loss of food and shelter for the wildlife that depend on them. To restore these vital trees, we gather acorns each fall with the help of volunteers, planting the next generation of oaks the following winter. Celebrate the fall season with us as we go "trick-or-tree’ting" for acorns!

This event is family-friendly and open to all ages! Minors must be accompanied and supervised by an adult for the entire event. Please wear long pants and comfortable closed-toe shoes, as volunteers will hike 1-2 miles on trails that may be uneven or include uphill and downhill sections. We’ll provide bags and buckets for collecting acorns. Please note that there are no restrooms on-site.

Space is limited, so be sure to RSVP to Angie at aleon@riversandlands.org to secure your spot.

Special thanks to our project supporters, Edison International and Inland Empire Resource Conservation District, for helping us restore and care for the oak woodlands at Cienega Canyon Preserve!
