Pollarding tends to make trees live longer by maintaining them in a partially juvenile state and by reducing the weight and windage of the top part of the tree. [6] Older pollards often become hollow, so it can be difficult to determine age accurately. Pollards tend to grow slowly, with denser growth-rings in the years immediately after cutting.
Plan to remove the supports after six months and check the tree for stability by gently pushing against the trunk; if the root system moves with the trunk, reattach the supports for one more season.
Larger trees can be climbed and a tape measurement made from the highest point of the climb to the base of the tree. The distance to the top of the tree can be measured from that point, if needed, using a pole. Historically the most direct method of finding a tree's height was to cut it down and measure it prostrate on the ground. [citation needed]
On a slope this base point is considered as halfway between the ground level at the upper and lower sides of the tree. Tree height can be measured in a number of ways with varying degrees of accuracy. Tree height is one of the parameters commonly measured as part of various champion tree programs and documentation efforts.
The distance should be measured along the side of the trunk from the base point of the center of the tree. The measurement is taken at a right (90 degree) angle to the trunk. Some groups recommend measuring the girth at breast height on the upper side when the tree is on a slope rather than from midpoint on the slope.
The undercut or notch cut is the guiding or aiming slot for the tree and is a V-shaped notch placed on the side of the tree in the direction of intended fall. [4]The back cut or felling cut is made on the opposite side of the tree of the undercut and is cut through the base of the tree severing the “hinge” holding the tree up.
