In an effort to put a monetary value on trees’ benefits, Ana Luisa Soares, a landscape architect at the University of Lisbon adapted a US software program, iTrees, and fed it data from Lisbon’s 41,000-odd trees. She found that while the trees cost about $1.9m annually, the services they provided were worth $8.4m.
