Trees save lives. Using data on temperature, tree canopy cover, demographics & mortality in Chicago from 2011-2021, researchers found that “neighborhoods with increasing year-to-year tree canopy had lower associated death rates.” 🌳 Learn more: doi.org/10.1029/2025... #urbanforestry #urbanforests

Did you know that street trees can have transplant shock? It’s normal for a tree to experience shock when it's removed from its container and planted in the ground. Transplant shock can look terrible (defoliation, leaf yellowing, wilting), but it’s usually temporary and not fatal to the tree. 🌳
