Hollywood’s iconic image of Los Angeles has long been defined by its palm-lined boulevards and sun-drenched landscapes. Yet these emblematic trees, while visually striking, offer minimal shade and demand significant resources to sustain. As climate pressures intensify, city planners and environmental experts are reevaluating the role of palms in L.A.’s urban forest. Unlike native species, most palm trees in the region were introduced during the 19th and 20th centuries, meaning many are now reaching the end of their lifespan and require replacement. With over one million trees across the metropolitan area—making it the largest urban forest in the U.S. by total count, though less dense than New York’s—the city is at a crossroads in shaping its green infrastructure for the future.
A strategic plan targeting 2028, coinciding with both the centennial of the Academy Awards and the city’s third Olympic Games, aims to increase tree canopy coverage by 50%. This initiative prioritizes large-canopied species that provide substantial cooling benefits, a critical factor as temperatures rise. Notably, palms are largely excluded from this expansion due to their limited shading capacity and high maintenance demands. Currently, just four neighborhoods enjoy 20% of the city’s total tree shade, highlighting disparities in urban greening that the new policy seeks to address through community engagement and combined public-private funding.
Financial investment remains a challenge. Data from the Los Angeles City Plants program reveals the city spends only $6.30 annually per resident on green spaces—the lowest among major U.S. cities. This equates to roughly $27 per tree each year, far below San Francisco’s $78. Meanwhile, palm upkeep is costly: they consume large amounts of water, require specialized pruning, and can harbor pests like rodents. Their flammability also raises concerns in fire-prone regions. Despite these drawbacks, palms hold cultural and historical significance. Developers in the late 1800s leveraged their tropical appeal to attract Eastern migrants, and in 1932, thousands were planted ahead of the first Olympics hosted in the city—many of which still stand today.
One particularly famous specimen, located in Exposition Park—site of the upcoming 2028 Games—has become a local landmark, complete with its own Wikipedia entry. Due to its age and fragility, maintenance now requires cranes rather than climbers. Past threats, such as a fungal outbreak in 2006 that affected Canary Island date palms imported centuries ago, have already wiped out many trees, especially in high-visibility areas like Melrose Avenue and Beverly Hills, where infection spread via contaminated pruning tools.
Urban development continues to impact tree populations. While the city follows a two-for-one replanting policy during construction projects involving subways, airports, and new buildings, it takes decades for new trees to mature and provide meaningful shade. Compounding the issue, the Urban Forestry Division’s budget was cut by $1.1 million in 2024, according to the Los Angeles Times, limiting its capacity to manage 700,000 trees under its care.
The debate over L.A.’s arboreal identity persists. Specialists advocate for more sustainable and functional alternatives, such as jacaranda trees, whose vibrant purple blooms enhance both aesthetics and biodiversity. However, in a sprawling metropolis where consensus is difficult to achieve, palm trees remain deeply embedded in the city’s visual identity—even as practical and environmental considerations push for change.

Los Angeles without palm trees? An aesthetic, economic and climate debate grips California
Hollywood has portrayed Los Angeles as a city of palm trees. Long streets lined with them, beaches decorated with them, elegant hotels surrounded by them, and convertibles whistling along beneath their shade… or not. Because shade is the crux of the matter. Stylized and aesthetic, palm trees hardly provide any shade, which becomes an issue in times of climate change. They are also expensive to plant and maintain and are forever thirsty. To make matters worse, they are in danger of extinction since palm trees are not endemic to California. They are relative newcomers, like the people who populate L.A. n nAlthough they have adapted to the mild climate of the West Coast, in reality a good part of the city’s palm trees are imported. Many of its varieties were planted during the 19th and 20th centuries. This means they are on their last legs, and the city has to start thinking about the trees it wants going forward. The Los Angeles area has one million trees, the largest forest park of any city in the country, although New York’s is denser. n nThe city has a roadmap that takes it to 2050. But for 2028, the year in which the Oscars will celebrate their 100th anniversary and the city’s third Olympic Games will be held, decisions have been made. In a report released in August 2021, it was explained that 20% of the shade produced by the city’s trees is afforded to just four neighborhoods. By 2028, the aim is to expand shade by 50%, through support from communities as well as municipal and private funds, for the planting and conserving of large trees, with canopies of least 75 centimeters, which will generally exclude palms. n nTo reach this goal, investment is needed. And curiously, L.A. invests the least in greenery of all U.S. cities, according to the Los Angeles City Plants program: just $6.3 per person per year. Per tree, this amounts to just $27 a year compared to neighboring San Francisco which invests $78. n nPalm trees are difficult to maintain. Their water consumption is high, their pruning complex, and sometimes they become nests for rats. They also burn easily and generate little shade. But they’re so beautiful that the savvy builders who developed the city in the late 19th century knew they would help sell sunny California to migrants from the East. And in 1932, tens of thousands of Mexican palm trees were planted to cheer the city up for its first Olympic Games. Many of them still survive. n nThe oldest of all the palm trees, now located in Exposition Park — precisely where the next Games will be held — has moved so many times and is so well known that it even has its own Wikipedia page. It is so old that the workers no longer climb it to prune it but tear its old leaves off from a crane. In 2006, there was a fungal plague that wiped out dozens of palm trees imported in the 18th century, the so-called Canary Islands palms. The disease and the advanced age of these meant that almost half of them became infected – disease being transmitted by pruning tools, it turned out – and many did not survive, especially in iconic areas for tourists and locals such as Melrose Avenue and Beverly Hills. n nIn the 21st century, with the subway system and the airport expanding, and new museums and housing developments being built, many trees have been uprooted and, although two are planted for every one that is removed, the shade takes years to arrive. Not to mention that in 2024, the budget for the Urban Forestry Division, responsible for 700,000 trees, was reduced by $1.1 million, according to the Los Angeles Times. n nDebate over the trees is now widespread. Experts complain and clamor for less demanding species, such as the beautiful jacarandas, which dye the streets purple in the spring. But, for now at least, in a monstrous city where it is hard to make decisions, the palm trees continue to feature prominently in postcards and movies.
