What Is a Tree Warden?

A tree warden is a person in charge of shade trees on public town lands. The word “warden” was a common title for natural resource officials in the late 1800s. Being a warden signified a unique legal responsibility: to guard public resources against destructive forces that might include persons, insects, or diseases.

Since 1899, Massachusetts General Law has mandated that all cities and towns in the Commonwealth have a tree warden who is responsible for trees on public property. The tree warden mandate is still in effect today under Massachusetts General Laws, Chapter 41, Section 1 and Section 106.

A tree warden may be either elected by the people or appointed by the city or town. In either case, the responsibility is the same – to oversee the care, maintenance, or removal of all public shade trees. As both manager and advocate, the tree warden must protect the trees and, where necessary, protect the public from the trees.

The scope of the job is broad and includes responsibility for all community trees – on streets and town commons as well as in parks, schoolyards, and town forests. The position of tree warden requires qualified training in arboriculture, the science of tree care. A tree warden should also have good communication skills for dealing with the public, municipal department heads, and local politicians.
The job may be physically challenging as well. On a day-to-day basis, a tree warden must plan, organize, control, and be accountable for all authorized activities in the public community forest, including

  • Pruning of trees for safety and health
  • Removal of trees that are dead or dying (from storms, insects, disease, or old age)
  • Identification of appropriate planting sites
  • Planting new trees
  • Creation or updating of a tree inventory, often on computer
  • Assessment of trees for potential hazards to public safety
  • Oversight of utility arboricultural operations
  • Preparation of budget presentations
  • Supervision of town tree workers
  • Creation of bid proposals for contract tree work
  • Inspection of contracted tree work
  • Conduct of public meetings and tree hearings
  • Writing grant proposals
