    TEXT VERSION OF TITLE SLIDE:

    Title: Trees that side scar easily
    Type: Text and Image Slide
    Content:

    1. In standard felling, the sides of the hinge between the notch and the back cut are not sawn when the tree starts to fall.

    2. As the tree falls, there is strain on the sides of the tree along the dotted lines. (circled area)

    3. Instead of breaking with the hinge, strips along the side of the tree rip off the stump, resulting in side scars.

    4. To prevent side scarring, corner to a depth of one inch before making the back cut.
