Conn. Gen. Stat. § 23-59
The town or borough tree warden shall have the care and control of all trees and shrubs in whole or in part within the limits of any public road or grounds and within the limits of his town or borough, except those along state highways under the control of the Commissioner of Transportation and except those in public parks or grounds which are under the jurisdiction of park commissioners, and of these the tree warden shall take the care and control if so requested in writing by the park commissioners. Such care and control shall extend to such limbs, roots or parts of trees and shrubs as extend or overhang the limits of any such public road or grounds. The tree warden shall expend all funds appropriated for the setting out, care and maintenance of such trees and shrubs. The tree warden shall enforce all provisions of law for the preservation of such trees and shrubs and of roadside beauty. The tree warden shall remove or cause to be removed all illegally erected signs or advertisements, placed upon poles, trees or other objects within any public road or place under the tree warden's jurisdiction. The tree warden may prescribe such regulations for the care and preservation of such trees and shrubs as the tree warden deems expedient and may provide therein for a reasonable fine for the violation of such regulations; and such regulations, when approved by the selectmen or borough warden and posted on a public signpost in the town or borough, if any, or at some other exterior place near the office of the town or borough clerk, shall have the force and effect of town or borough ordinances. Whenever, in the opinion of the tree warden, the public safety demands the removal or pruning of any tree or shrub under the tree warden's control, the tree warden may cause such tree, shrub or group of shrubs to be removed or pruned at the expense of the town or borough and the selectmen or borough warden shall order paid to the person performing such work such reasonable compensation therefor as may be determined and approved in writing by the tree warden. Unless the condition of such tree, shrub or group of shrubs constitutes an immediate public hazard, the tree warden shall, at least ten days before such removal or pruning, post on each tree or shrub and may post on each group of shrubs a suitable notice stating the tree warden's intention to remove or prune such tree, shrub or group of shrubs. If any person, firm or corporation objects to such removal or pruning, such person, firm or corporation may appeal to the tree warden in writing, who shall hold a public hearing at some suitable time and place after giving reasonable notice of such hearing to all persons known to be interested therein and posting a notice thereof on such tree, shrub or group of shrubs. Within three days after such hearing, the tree warden shall render a decision granting or denying the application, and the party aggrieved by such decision may, within ten days, appeal therefrom to the superior court for the judicial district within which such town or borough is located. The tree warden may, with the approval of the selectmen or borough warden, remove any trees or other plants within the limits of public highways or grounds under the tree warden's jurisdiction that are particularly obnoxious as hosts of insect or fungus pests.

Tree warden doing this work himself, for pay, comes under workman's compensation act. 102 C. 573. Exclusive control in warden over trees within highway, or parts thereof, even though trees themselves stand on private grounds. 128 C. 674. Cited. 26 CA 599. Court's jury instruction re tree warden statute was correct in law. 68 CA 284. In view of Supreme Court decision and statutes vesting exclusive control in town tree wardens over trees located in whole or in part in public roadways, court correctly held that owners of private, adjoining land were not liable to plaintiffs injured by falling tree, despite the fact that private landowners unintentionally created the condition that caused the tree to decay and fall, upon facts that demonstrated private landowners gave town timely notification of the decay before tree fell. 97 CA 31. Some of the duties of town tree warden, including duty to inspect upon receipt of complaint concerning potentially hazardous tree, are ministerial, but failure to inspect means that discretionary act governmental immunity does not apply. 135 CA 364. Exclusive control of all trees standing in whole or in part within limits of a highway is vested in town or borough tree wardens even though trees stand on private grounds. 17 CS 108.
