make stub cuts (an inch or more beyond the branch collar). Contractor will not make flush cuts (through the branch collar). B. Triple cuts. For any branch too large to be held while being cut, Contractor will remove by means of the following cuts: • Under cut the branch 4 to ]0 inches beyond the base (to prevent splitting or peeling). • Cut off the branch beyond the undercut where necessary, to prevent property damage. Branches shall be lowered to the ground by ropes and/or proper equipment. • Remove the remaining stub via shoulder cut, as described above. Removal of terminal (tip thinning and drop crotching) A. Thinning. Contractor shall "lace out" terminal portions of branches by cutting terminals back to laterals. (The basal diameter of the remaining lateral should be 1/3 the diameter of the terminal being removed.) Contractor shall remove numerous small terminals and laterals rather than take out a few large one. B. Size reduction. To take out portions of the crown for reducing height, Contractor shall remove terminals back to laterals. Each lateral should be suitably situated to serve as the new terminal, thus establishing the crown at a lower level. The basal diameter of a lateral should be at least 1/3 the basal diameter of the terminal being removed. (Laterals smaller than this cannot function effectively as new terminals, and the effect is then similar to a stub cut.) 2. Branches that pose a threat to the health, safety, and welfare of the general public shall be removed. In addition, branches that disrupt the aesthetic or general integrity of the tree shall be removed. Kinds of branches to be removed: A. Obstructing branches. Clear walks, traffic ways, buildings and other man-made structures. Clear other trees, plants as needed. B. Dead, broken, diseased or weak branches. (Also stubs left by previous pruners). C. Crossing branches. This includes potentially crossing branches, also upright shoots (water sprouts) and vigorous and interior-directed branches. D. Narrow crotch-angle branches. For most kinds of trees, branches with a crotch angle narrower than 30 degrees should be removed. E. Parallel branches. Branches less than a foot apart which run parallel for several feet may eventually damage each other. The less desirable one should be removed. F. Wind-breakage risks. Crowns that are too high and/or too dense should be thinned, and sometimes lowered to suitable laterals. Reducing wind resistance by thinning 31
