N.J. Stat. § 40:64-10
No statute giving any person or State, county or municipal board, body or official, power or authority to lay any sidewalk along, or to open, construct, curb or pave any street, or to do any similar act, shall be construed to permit or authorize any interference with or injury to a highway shade tree without the consent of the shade tree commission within whose jurisdiction such tree shall be located. In all cases such commission shall reasonably co-operate with such person, board, body or official for the general public good.
Nothing in this chapter contained shall be held to take away or diminish any of the powers or authority of any county park commission over the trees or shrubbery in any county park or parkway within its jurisdiction, or to give any other commission or board any power or authority with respect to such trees or shrubbery.
