Due to climate change, Miami Beach moving away from palm trees to create more shade

Good News Notes:

“Whether swaying in the background of a Super Bowl glamour shot or printed on Art Deco-themed postcards, palm trees are synonymous with the sun-and-fun allure of Miami Beach. In a city with nearly 50,000 trees, more than half have fronds.

But because of rising temperatures, that’s about to change.

To help address the consequences of climate change,  will cut back on the number of new palms in the  and add more eco-friendly  trees to the Beach’s canopy.

Guided by an urban forestry master plan, which the Miami Beach City Commission unanimously approved in October,  are working to reduce the concentration of palms to 25% of the total canopy by 2050. The city says the cutback—intended to help reduce urban warming, improve air quality and absorb more carbon and rainwater—will be accomplished during upcoming construction projects that already require the removal of trees, partly by removing some palms but mostly by adding new shade trees.

‘Palms, while an iconic part of Miami Beach’s landscape, have moved from being an accent plant to a major component of the city’s urban forest,’ the urban forestry master plan reads.

The execution of the plan has alarmed one city commissioner, who recoiled at a January memo that announced the coming removal of 1,000 palms. But Elizabeth Wheaton, the city’s environmental and sustainability director, told The Miami Herald that the city is not just going around chopping down .

‘Expanding shade canopy will enhance the city’s brand and quality of life,’ Wheaton wrote in an email. ‘Palms will continue to be a along the city’s roads, greenspaces and parks.’

Over the next 20 years, Wheaton said the city aims to plant more than 1,300 new shade trees per year. New shade trees will be added around existing palms to make the city more walkable and pleasant, she said, adding that trees like the royal poinciana and gumbo limbo ‘reduce the heat island effect, uptake carbon and rainwater, and improve air quality.’

It’s unclear how many fewer  trees Miami Beach may have in the coming decades, but Wheaton noted that the percentage of palms could be reduced by exclusively adding shade trees to the existing population.

Currently, the city has 22 active projects that require the removal of palms and trees. More than 1,000 palm trees are slated for removal, but 891 new ones will be planted—so 169 will be lost in the aggregate. Nearly 500 shade trees will be removed under the projects, but close to 900 will be added. The city code requires that any palms or other trees affected by redevelopment must be replaced with new shade trees.

‘Palms are not actively being removed, rather canopy trees are being prioritized for planting to increase the city’s tree canopy percentage citywide to maximize environmental, social, and economic benefits of trees,’ Wheaton said.

But talk of removing palm trees has created some friction.

Miami Beach Commissioner Steven Meiner has come out against the policy in recent weeks. He casts the program as a mass removal of palms that will damage the Beach brand and has rallied some residents behind his cause.

At Meiner’s request, the city will hold a video meeting March 2 at 4 p.m. to discuss the plan and hear from residents.

‘The removal of so many iconic, beautiful palm trees, including royal palms, will have a negative impact on our historic, cultural and economic brand,’ Meiner wrote in an email. ‘Millions of tourists throughout the U.S. and the world annually visit Miami Beach and palm trees are an integral part of our brand. There are only a handful of tropical climates in the United States where palm trees can grow.'”
