A study by UTS shows that suburbs with dense tree canopies have lower concentrations of particulate matter in the air – cleaner air. Tree canopies help with disperse particulate pollution that is responsible for cancers and respiratory diseases, like asthma.
The total tree canopy cover across the City of Sydney local government area is about 15.5%, including 6.6% on private land, 4.9% from street trees and 4.1% in parkland.
Dr Fraser Torpy from UTS said “Grass didn’t have a positive impact on air quality at all: it is trees and canopy density that are the important factors in reducing air pollution and particulates.”
