The US Forest Service has developed an app to help cities quantify the value of their trees. Landscape lovers know that they’re good for climbing, picnicking and napping under, contemplating, watching bud and bloom, and leaning against. But now planners and environmentalists are assigning dollar values to trees and other natural resources to tally up the environmental services they provide, from filtering air and water to storing carbon and cooling buildings in summer with their generous, leafy shade. We know how much it costs to cool a building with air conditioning, so what if we measured the dollar value of cooling tree shade? As with all good design solutions, trees solve many problems at the same time, not the least of which is making our world more beautiful.
