2×Street Trees per Mile vs. avg city
Santa Monica maintains one of Southern California's most celebrated urban forests — roughly one tree for every three residents. The city's Public Landscape Division oversees planting, pruning, health assessments, and removal of public trees, guided by an Urban Forest Master Plan first published in 2011 and updated in 2017. The forest faces a critical renewal challenge: 42% of its trees are mature and nearing the end of their useful life, making aggressive replanting a top priority.
A Living Arboretum by Design
Santa Monica's urban forest is no accident. In the early 20th century, city arborists specified trees for long stretches of streetscape — effectively writing names of trees onto street maps and creating a citywide arboretum that still grows today. The 1956 book Trees of Santa Monica by Georg Hofer documented what had already become a defining civic asset.
The result is a remarkable street-level diversity: Mexican fan palms (Washingtonia robusta) create dramatic arcades along major corridors; Moreton Bay figs (Ficus macrophylla), native to eastern Australia, spread massively in open areas like Palisades Park, with roots that erupt through pavement and limbs that wind dramatically through the air; coral trees, Brisbane box, and dozens of other species give each neighborhood its own canopy character.

Landmark & Heritage Trees
Santa Monica's most iconic individual trees carry their own histories:
- Miramar Moreton Bay Fig — A Ficus macrophylla planted in the 1880s when Santa Monica was still a summer holiday destination. In an open setting it can spread up to 150 feet wide; this specimen stands as one of the city's most recognized landmarks.
- Palisades Park Canopy — The bluff-top park overlooking the Pacific is lined with mature Moreton Bay figs, palms, and eucalyptus, forming one of the most photographed urban tree corridors in California.
- La Mesa Drive Figs — This residential street is defined by unruly Moreton Bay figs whose roots have erupted through the ground, creating an almost otherworldly streetscape.
The city maintains a Heritage Tree Map layer within its public tree database, allowing residents to explore and locate protected specimens.

Ecosystem Benefits
Urban trees deliver measurable value beyond aesthetics:
- Air quality — Trees filter particulates and absorb pollutants, critical in a coastal city subject to marine layer inversions that can trap emissions.
- Heat island mitigation — Tree canopy reduces surface temperatures, particularly important as Southern California summers intensify.
- Stormwater management — Root systems and canopy interception reduce runoff into the storm drain system and, ultimately, the ocean.
- Carbon sequestration — Each mature tree sequesters meaningful carbon; at 35,000 trees, the collective benefit is substantial.
- Mental health & walkability — Research consistently shows that tree-lined streets encourage walking and reduce stress, aligning with Santa Monica's pedestrian-forward urban planning goals.
Renewal Urgency With 42% of trees classified as mature and nearing end of life, Santa Monica faces a generational transition in its urban forest. The city has acknowledged the need to escalate its tree planting program, pursue grant funding, and require new development projects to incorporate trees. Without proactive action, canopy coverage could decline significantly over the next two decades.
Management & Governance
The Public Landscape Division maintains all public street and park trees with certified arborists who perform routine inspections, risk assessments, pruning, and removals. The Urban Forest Task Force — a civic body — meets regularly to guide policy.
The city's Urban Forest Master Plan (2011, updated 2017) sets a 50-year strategy focused on:
- Increasing age and species diversity
- Augmenting biomass and canopy coverage citywide
- Enhancing neighborhood character and aesthetics
- Achieving exemplary long-term stewardship
