In what order do you pass through the layers of a tree when cutting with a chainsaw?

When cutting through the layers of a tree with a chainsaw, the correct order is to go through the bark first, followed by the phloem, then the cambium, and finally the xylem.

The bark is the outermost protective layer of the tree, serving as the first barrier against physical damage and pests. Once the chainsaw penetrates the bark, it reaches the phloem, which is responsible for transporting nutrients (specifically sugars) produced by the leaves down to the roots. Just beneath the phloem lies the cambium, a thin layer of actively dividing cells essential for the growth of new phloem and xylem. Finally, upon cutting through the cambium, you reach the xylem, the central layer that transports water and minerals from the roots to the leaves and provides structural support to the tree.

This understanding of tree anatomy is crucial for arborists as it helps in making informed decisions about tree care and the implications of cuts made at different layers.
