Poplars are ill-suited to cope with climate change for two reasons: their roots do not penetrate deeply enough to withstand the increasing water stress, and their height makes them vulnerable to the increasingly frequent storms, even in Brianza. In April, out of 271 poplars planted 25 years ago, 116 had died (271 – 155), almost half. I requested permission to replace them with lime trees in the Regional Park of the Lambro Valley but, to date, after several months of waiting, I have received no response.
