Barry Burton, assistant to the mayor for landscape issues, said Mayor Daley ordered all city departments to replace trees on a regular basis after he noticed a huge loss in the city's tree canopy.Burton said when budget figures showed that new trees added only a 2 or 3 percent increase, "the ball really started rolling."
Burton said the mayor is also committed to diversification of species.The city's tree list now includes hackberrys and hawthorns, Turkish filberts, Kentucky coffeetrees, and swamp white oaks.Burton favors two new disease-resistant elms."The American elm that came out of the Morton Arboretum called Accolade promises to be really great," he said."The latest one is called Century, and it promises to have that perfect large vase shape that we are missing so much right now."
Burton says Chicago has "very aggressive greening goals for the city overall."That includes 63 miles of landscaped medians, flowers and plants that absorb storm water runoff, and more than 70 green roofs either in planning stages, under construction, or completed, including one on top of city hall.
"It helps cool down buildings and saves energy," he said, "and it also helps with air pollution."
According to Burton, studies conducted with federal agencies indicate that every 11 trees the city plants removes the equivalent of one car's emissions."It's a great way to make your city look beautiful and also improve the environment and air quality," he said.
