Pavement and other impervious cover increased at a rate of about 167,000 acres a year during the same period, according to research by USDA Forest Service scientists.

Nationally, urban/community tree cover declined from 42.9 percent to 42.2 percent. Twenty-three  had a statistically significant decrease in tree cover, with a total of 45 states showing a net decline. Trees improve air and water quality, reduce summer energy costs by cooling homes, reduce noise, mitigate runoff and flooding, and enhance human health and well-being, making them important to human health and urban and community infrastructure. The annual benefits derived from U.S. urban forests due to air pollution removal, carbon sequestration, and lowered building energy use and consequent altered power plant emissions are estimated at $18 billion…”
