Name 3 types of notches used in tree felling.

The choice mentioning Open face, Traditional (45 degrees), and Humboldt notches accurately captures three significant types of notches utilized in tree felling techniques.

The Open face notch is essential as it creates a clear direction for a tree to fall, reducing the likelihood of unpredictability during the felling process. This notch type allows for a more controlled and gradual release of tension, leading to a safer operation.

The Traditional (45 degrees) notch is a classic method that creates a wedge-shaped cut aimed at guiding the directional fall of the tree. This method has been widely used and taught due to its simplicity and effectiveness in ensuring that the tree falls in the intended direction.

The Humboldt notch is particularly beneficial in situations where the tree has heavy lean or tension, as it maintains a smaller profile on the side facing the tree's intended direction of fall. This notch allows the faller to better assess the lean and make adjustments as necessary.

These three notches are crucial for effective and safe tree felling, and they emphasize directing the fall, managing tree stress, and creating pathways for safe execution of the cut. The other choices either include notches that aren’t standard terminology in tree felling or mix options that do not illustrate the different techniques as effectively.
