摘要： PROBLEM TO BE SOLVED: To provide a guide for tree logging with which trees safely and reliably fall down in a prescribed direction.SOLUTION: The guide for tree logging is made up as follows: a sheet 2 cylindrically wound and mounted around the trunk of a tree 10 is provided with: a lower cut line 3 formed along the horizontal direction of the sheet 2; diagonal cut lines 4 being equilateral sides of an isosceles triangle having the lower cut line 3 as a bottom side; and saw side cut lines 5formed on a side of the isosceles triangle along the horizontal direction. The angles of the diagonal cut lines 4 based on the lower cut line 3 is 30-45 degrees. The intervals h, h, and hbetween the saw side cut lines 5 and the lower cut line 3 respectively correspond to about 2/3 of the heights H, H, and Hof a back side 11. The lower cut line 3 has such a length that the cut length D of the lower cut is 1/4 or more of the diameter of the trunk. The saw side cut lines 5 have such a length that the width L of a hinge is about 1/10 of the diameter of the trunk. The heights H, H, and Hhave the distance of P-P, P-P, and P-P, respectively.
