CLOSURE NOTICE: All ACR preserves in Marin and Sonoma counties remain closed until further notice due to the public health risks of Covid-19. Resident preserve managers and stewardship staff continue to protect and steward these incredible resources for both natural and human communities. We hope to see you on the trail in the near future. While you are exploring nature nearer to home, please visit our Nature Where You Are resource page for engaging nature content, lessons for all ages designed by ACR educators and links to some of our favorite science-based nature resources.
Steep, Wild Country, No Facilities
A favorite spot for birding, the Modini Preserve is traversed by Pine Flat Road, a public county road that meanders through the Preserve allowing visitors to enjoy the views and birdwatch from roadside public pullouts anytime without appointment. Please drive very cautiously, this is a one-lane winding road with very limited sight lines.
The Modini Preserve Stewards provide essential hands-on assistance to our land management team, including trail maintenance, invasive plant removal, native plant propagation, and other special projects. Come learn more about the Preserve by getting your hands dirty!
We meet on the 2nd and 4th Thursdays of most months from 9:00 a.m. – 1:00 p.m., as well as the last Saturday of every month, 10:00 a.m. – 1:00 p.m. To learn about our stewardship program or the Modini Preserve Stewards, contact ACR Resource Ecologist Julianne Bradbury by email or call 707-396-8832.
The Modini Preserve is located above Alexander Valley near Healdsburg, California, in the Mayacamas Mountains.
Pine Flat Road is about 7 miles northeast of Healdsburg.
