A person who uses any type of device, including but not limited to wire or cable, that is not a fence but is installed at a height under 10 feet from the ground, to indicate boundary lines or otherwise to divide, partition or segregate portions of real property, if the device is not readily visible or marked in such a way as to make it readily visible to persons who are pedestrians, equestrians, bicyclists or drivers of off-the-road vehicles and poses a risk of causing significant bodily injury to such persons, shall be guilty of a crime of the fourth degree. However, this section is not intended to apply to markers set by a licensed land surveyor, pursuant to existing statute.
