An Act to update the public shade tree law

This bill updates Massachusetts' public shade tree law (Chapter 87) to clarify and strengthen tree management procedures. It requires tree wardens in cities with over 10,000 residents to hold professional arborist licenses and meet specific training standards (e.g., accredited degrees or certifications). The bill also clarifies that tree wardens (or authorized officials) may trim or remove hazardous trees without a hearing if they pose immediate threats, while requiring others to consult the tree warden before altering public trees. Violations of tree care rules now carry fines based on the tree's assessed value, with funds directed to local municipalities. The changes primarily affect town/city tree wardens, municipal authorities, and residents seeking to modify public trees.
