The HCI Tree Cover indicator measures the amount of tree canopy within the neighborhood. Numerous positive health outcomes are related to increased tree coverage: trees absorb air pollution and release oxygen which has been shown to enhance respiratory health, reduce fatigue and increase productivity; they promote physical activity, lower stress, and help control weight. Tree also absorb and block sound, with the ability to reduce noise pollution by as much as 40 percent. Finally, tree cover reduces exposure to UV rays, the cause of sun burns and skin cancer, and lowers air temperatures. Listed under Natural Areas, tree cover also impacts economic health, health systems and public safety, housing, neighborhood characteristics, social cohesion, and environmental hazards. Data on Tree Cover is available from the U.S. Geological Survey’s (USGS) National Land Cover Dataset (NLCD).
