When it rains, New York City's natural areas-made up of forests, wetlands, and grasslands-play a crucial role in keeping sewers from overflowing by soaking up 17 percent of the city's stormwater, a new report by the Natural Areas Conservancy (NAC) finds. The report reveals that this natural landscape, which makes up a third of the Big Apple's more than 30,000 acres of parkland, soaks up twice the amount of storm water on a per unit basis when compared to other forms of green infrastructure like rain gardens.
On a recent morning, as the late August sun began to beat down, a few dozen New Yorkers stood in the shade of one of the nearly 500 trees adorning Harlem's Marcus Garvey Park, worrying a bit about hurting its feelings. We had already identified the species bald cypress thanks to its feathered leaves and strong pyramidal shape, measured its trunk's circumference (17in; 43cm), and noted that its roots appeared normal, its leaves were healthy and its branches had suffered some damage from improper pruning.
