poodle cut
n.— «Lygodium, or Old World climbing fern, covers trees like a green blanket. Workers use a technique called “poodle cut” on lygodium vines, carving deeply into the thick vegetation near the base, which kills the vine’s growth above the cut.» —“Loxahatchee National Wildlife Refuge slugs it out with exotic invasive plants” by Lona O’Connor Palm Beach Post (Florida) Mar. 20, 2009.
