Trees lining city streets, in public and private gardens, in parks, and in patches of urban woodland do a lot for cities. They help mitigate air pollution, lessen the urban heat island effect, provide flood control, and contribute a host of other benefits. Some studies have valued these ecosystem services at almost USD $1 million per square kilometer per year.
And it turns out that these trees, collectively known as the urban forest, also contribute more than you might imagine to carbon sequestration, according to a new study published in the journal Carbon Balance and Management.
