San Francisco's Urban Forestry Bureau faces scrutiny over tree maintenance and staffing issues

In a recent government meeting, San Francisco County officials discussed critical findings from an audit of the Department of Public Works, focusing on the city's urban tree canopy and street tree maintenance. The meeting highlighted the urgent need to address the city's tree coverage, which currently stands at just under 14%, significantly lower than other urban areas in the United States.

Dan Goncher from the Budget Legislative Analyst's Office presented the audit's findings, which revealed several key issues within the Street Tree SF program. The audit, conducted in response to a 2019 board motion, identified five main areas of concern regarding tree maintenance, including insufficient pruning progress, staffing shortages, and uneven geographic distribution of tree services. Notably, the program has only completed 21% of its planned pruning within the first three years, projecting an eight-year timeline to finish initial maintenance tasks.

The audit also pointed out that the city lacks a dedicated funding source for expanding its street tree population, which is crucial for maintaining and growing the urban canopy. Currently, the annual planting rate of approximately 2,154 trees falls short of the estimated 5,000 needed to offset tree mortality and sustain the population. This discrepancy raises concerns about the city's ability to meet its urban forest goals, which aim to increase the street tree population to 155,000 by 2034.

In response to these findings, the audit recommended several actions, including establishing realistic annual goals for tree pruning and sidewalk repairs, improving recruitment efforts for arborist positions, and developing a comprehensive citywide street tree management plan. The recommendations emphasize the importance of equitable tree distribution across neighborhoods, particularly in underserved areas.

The meeting underscored the significance of urban forestry in enhancing community well-being and environmental health. As San Francisco grapples with challenges related to climate change and urban development, the discussions highlighted the need for immediate action to reverse the trend of declining tree coverage and ensure a sustainable urban forest for future generations. The Board of Supervisors is expected to review the proposed strategies and funding plans in the coming months, marking a critical step toward revitalizing the city's green infrastructure.
