This urban oasis – neighboring UCSF’s Parnassus Heights campus, residential homes and the iconic Sutro Tower – includes the UCSF Chancellor's Residence and the Aldea San Miguel Campus Housing and Conference Center. The Reserve also features more than 5 miles of public, multi-use trails, with a 900-foot elevation gain, that cater year-round to hikers, trail runners, dogs on leash and cyclists.

Steeped in San Francisco History

Named for its former owner and San Francisco Mayor Adolph Sutro, the Reserve has a history of transition much like many San Francisco neighborhoods.

A successful engineer and real estate investor, Adolph Sutro served as San Francisco mayor from 1894 to 1896. Sutro’s many land holdings included Mount Parnassus, which was renamed Mount Sutro in his honor.

In 1886, Sutro began planting the hill with imported and native trees to celebrate San Francisco’s first Arbor Day.

Sutro donated 13 acres of land on Parnassus Avenue to the UCSF Regents in 1895 for development into the UCSF Parnassus Heights campus.

Sutro’s death in 1898 led to years of legal battles among his heirs, culminating in 1909 with a deal between the Sutro estate and Consolidated Eucalyptus Company to log and process trees across more than 1,500 acres on Mount Sutro. The logging operation closed in 1934 after a 10-acre fire turned neighbors against the lumber mill.  During the Cold War, Mount Sutro was home to a Nike missile site.

In 1953, UCSF purchased a 90-acre parcel to the south of the original parcel donated by Sutro, and most of that is now the Mount Sutro Open Space Reserve. In 1976, UCSF designated 58 acres of the Reserve as permanent open space and subsequently increased the size to 61 acres. The area designated as the Mount Sutro Open Space Reserve shall be kept free of any permanent structures or facilities except footpaths and appropriate landscape construction intended to enhance its use as a natural area. 

UCSF’s Commitment

UCSF is committed to maintaining the Reserve as an important natural resource for San Franciscans and takes seriously its responsibility to keep the site safe and accessible. 

To preserve the beauty, safety and accessibility of Mount Sutro, UCSF Facilities Services performs ongoing general maintenance throughout the Reserve and its trails. UCSF has two certified arborists on staff who are dedicated to preserving the beauty of the natural environment.

Ongoing general maintenance of the Mount Sutro Summit, trails, roadways and areas adjacent to structures and neighboring homes includes:

Removal of storm debris, downed trees or branches, hazardous trees, broom, trash, and campsites

  • Management of overgrown vegetation
  • Bi-annual removal of invasive sprouts
  • Scheduled tree pruning
  • Drain clearing
  • Security patrol

In line with our commitment to a healthy and sustainable Reserve, we discontinued the use of herbicides in 2008. All work is performed using hand and mechanical tools or goats to control vegetation growth. 

Our regular maintenance is independent of the Reserve management plan that is currently being developed and the fire mitigation and hazardous tree removal projects performed as necessary to respond to potentially dangerous conditions in the Reserve.

Visit or Volunteer


Visitors will enjoy an abundance of rare and native plants, as well as many species of trees including  Monterey Pine, Monterey Cyprus and Blue Gum Eucalyptus. At the summit of Mount Sutro is Rotary Meadow, our native plant garden and demonstration area.

There are no public parking areas on Mount Sutro, so we encourage our visitors to take public transportation or to park on Clarendon Avenue.

Public Transportation:

Take the #6 or #43 Muni bus lines to Parnassus Avenue (Willard stop). Walk along Medical Center Way and walk up the stairs to the trailhead.

Street Parking:

Park on Clarendon Avenue near Johnstone Drive. Walk past the Aldea Center along Johnstone Drive to reach the trailhead.

The Sutro Stewards is a non-profit stewardship program of the San Francisco Parks Alliance. In partnership with UCSF, the dedicated Stewards volunteers build and maintain the nearly 5 miles of trails, as well as perform conservation and habitat restoration work.

Craig Dawson, a native San Franciscan, founded the Stewards in 2006. Dawson has been active as an advocate for protecting and preserving Mount Sutro since he joined UCSF’s Community Advisory Group in 1992.

The Stewards work closely with UCSF’s Facilities Department and have logged thousands of hours building and maintaining the trails. They also helped to develop Rotary Meadow, the native plant demonstration area identified in the 2001 Sutro Plan and funded by the Rotary Club. The Stewards organize volunteer days and manage the supervision and training of the volunteers.

Reserve Management Plan

UCSF’s top priority is to ensure the safety of the Reserve for our residents, patients, visitors, campus buildings and neighboring homes. Across California, the severe multi-year drought caused widespread decline in the overall health of trees, resulting in at least 66 million dead trees statewide. This decline is also evident in the Reserve. In response, UCSF began a process in 2015 to develop a management plan to ensure the long-term health and sustainability of the Reserve. Details about the plan reside below, but if you have any other concerns, please read our frequently asked questions.


Current Conditions of the Mount Sutro Open Space Reserve

The last several years of drought, disease, and the age of the Mount Sutro’s stand of trees have led to a decline in the overall health of the forest. Overall, there are too many trees in the Reserve to support a healthy canopy. Under ideal conditions, the forest should have many more small-diameter trees than large-diameter. At present, this is true in only a third of the Reserve, but a large proportion of those trees are either dead or in poor health.

There is abundant evidence to suggest that the existing forest will not recover on its own. The data show a continuing trend of declining tree health. Recent years have seen below-average rain, which may continue into the future. For these reasons, we believe the only path to healthy diverse vegetation involves active management and regeneration.

Public Process

To develop the proposed vegetation management plan for the Reserve, UCSF led an extensive public process involving expert, community, and environmental review and revisions. UCSF has published and approved its final plan to manage the Mount Sutro Open Space Reserve over the next 20 years.

The public process included a Technical Advisory Committee (TAC) comprised of local experts in forestry, hazard reduction, biology, and habitat restoration to provide guidance on best practices in forest management. UCSF held four TAC meetings, which were open to the public, followed by two community meetings and public tours of the Reserve, giving the public many opportunities to help shape the final plan, discuss their concerns and provide feedback.

Environmental Review Process

As required by the California Environmental Quality Act (CEQA), the Environmental Impact Report (1) assessed the potentially significant environmental effects of the proposed project, including cumulative impacts of the proposed project in conjunction with past, present, and reasonably foreseeable future development; (2) identified feasible means of avoiding or substantially lessening significant adverse impacts; and (3) evaluates a range of reasonable alternatives to the proposed project, including the No Project alternative.

As a result of the extensive public review process, the environmental review determined that small variations of the original draft plan would mitigate some potential impacts and improve the health of the forest. These variations were outlined in Alternative 4, one of the alternatives studied in the EIR. Alternative 4’s variations included a change to the tree planting species mix in the first phase (five years) of the plan, from replanting only eucalyptus trees to a planting mix of 75% eucalyptus and 25% native species. Also, tree replanting areas will be smaller than in the original plan and located further from trails to lessen visual impacts and improve the overall experience for visitors to the Reserve.

The final plan adopts Alternative 4 as the project. It was approved by UCSF’s Chancellor on April 30, 2018. UCSF will begin the first phase of implementation after bird-nesting season in September 2018.

Support for the Plan

UCSF’s proposal to manage the Mount Sutro Open Space Reserve is supported by many neighbors, open space advocates and community and environmental groups, including:

  • California Native Plant Society
  • Inner Sunset Park Neighbors
  • Nature Conservancy
  • Rotary Club of San Francisco
  • San Francisco Department of the Environment
  • San Francisco Urban Riders
  • Sierra Club
  • Sutro Stewards

“After a thoughtful and interactive process with experts and the community, UCSF has developed a much-needed plan to restore the health of the Mount Sutro Open Space Reserve.” --Sierra Club

“As an organization that works with dedicated volunteers every week to maintain and improve Mount Sutro, we are personally invested in the health and longevity of the Reserve. We see firsthand the need to manage the open space for long-term sustainability, and we support UCSF's plan to regenerate the Reserve to a healthy, diverse ecosystem for all to enjoy.” --Sutro Stewards

“In large part, the City’s Department of the Environment implements the sustainability vision for the City and County of San Francisco, including promoting local biodiversity, the conservation of our natural heritage and equitable access and experience of nature in the city. We were very pleased to participate in the Technical Advisory Committee, and we support the overall vision of the Vegetation Management Plan.” --Peter Brastow, Senior Environmental Specialist, Biodiversity, San Francisco Department of the Environment

“We are pleased to support UCSF’s Mount Sutro plan because of the extensive outreach and community support it has received.  Inner Sunset neighbors frequently visit the Mount Sutro Open Space with their families to enjoy a respite from their busy urban lives, and the effects of the drought have become far more apparent during the past few years. We support the proposals to improve the conditions and safety of the Reserve so that it remains exceptional sanctuary we all know and love for generations to come.” --Inner Sunset Park Neighbors Board

“The ecological health of the Sutro Forest is declining rapidly and significant intervention is needed, quickly, to fulfill the vision of the plan and protect San Francisco’s natural heritage for this and future generations. We urge quick action – to approve the EIR, the Plan and to get to work." --Louis Blumberg, California Climate Change Director, The Nature Conservancy


In keeping with UCSF’s commitment to responsible stewardship of the Reserve and its wildlife, UCSF will delay implementation until September 2018, after bird-nesting season.

During implementation over the next 20 years, there will be an ongoing assessment of the plan’s efficacy in reducing hazardous conditions and enhancing the ecological diversity of the Reserve. Regular updates will be provided to the community throughout the implementation process.

Technical Advisory Committee

California’s severe, ongoing drought has led to widespread decline in the overall health of the Reserve, a serious problem facing all forests and open space areas across the state.

UCSF formed a Technical Advisory Committee (TAC) to discuss our Mount Sutro Open Space Reserve Management Plan. In developing this plan, the University staff worked with consultants and a Technical Advisory Committee (“TAC”) comprised of experts with extensive experience in forestry, hazard reduction, biology and habitat restoration. All members are volunteered their time to assist in this important process. TAC members provided guidance on the scope, techniques and best practices for the management plan. TAC members included:

  • Peter Brastow, Biodiversity Coordinator, San Francisco Department of the Environment
  • Peter Erlich, Forester, Presidio Trust
  • Joe McBride, Professor Emeritus of Landscape Architecture and Environmental Planning, University of California Berkeley
  • Lew Stringer, Restoration Ecologist, Presidio Trust
  • Richard Sampson, Forester/Division Chief, CAL FIRE
