Roughly calculate the height of the tree. Then, use that measurement to guide you in determining the area around the tree where it will most likely hit the ground. Allow additional space at least twice the height of your tree. That area will be the fall path of the tree. Later on, you can cut the notch that will help direct the tree into the location you want it to fall. Also, identify the safe areas where you can run to when the tree starts to topple. You should have two options for your escape. Clear your escape routes of any obstructions and tripping hazards and keep a safe distance away from the falling tree. Accomplish some tree trimming before making the felling cuts to minimise the risks of injuries and damages.
