After the current storms end, California will face a new challenge: restoring an already diminished urban canopy. awalkerinLA reports
— a number that’s lower per capita than anywhere else in the U.S. Mature street trees are too scarce of a resource for the state to squander.
Street trees are tested for hurricane-speed winds in places like Florida, says McBride, but not so much in California, where towering, top-heavy American elms are among the gargantuan uprooted trees seen around Sacramento. He hopes that the disaster will urge cities to make changes in their replanting strategies.
Sacramento’s political prioritization of its urban canopy has been shown to help the city save on energy costs, and some residents may feel the loss of tree cover in their AC bills during hot summer days, says Hartin, an environmental horticulture adviser for the University of California’s Agriculture and Natural Resource research center in Riverside.
Even in the best of weather, California city life as it currently exists is not optimal for keeping trees alive. And many factors determining the survival of the state’s urban canopy are dependent on policies beyond forestry practices, says Megan Lynch, a horticultural scientist at the University of California, Davis, who spent six years studying street trees in Southern California. The biggest factor? “Car culture,” she says, decisively.
