Vegetation Management Guidelines from NJ & CT

Here is interesting reading concerning NJ's guidelines for vegetation management along transmission line ROWs. This has numerous diagrams (provided by the Rairitan Sierra Club) which clearly show the limits imposed by NERC/FERC regulations, as well as a more nuanced "tiered management" approach which looks at the simple geometry of risk (in terms of tree location, required clearances and wire heights.)

Here is another guideline from Northern Utilities serving CT and New England. Although more stringent, it also shows a "tiered management" approach - allowing Dogwoods and other low growing tree species to exist outside of the wire clearance zones.
