Trunk
The trunk is the primary structural pillar of a tree, transporting water and nutrients through vascular tissue while providing mechanical support for the canopy above. Trunk health directly affects the stability and longevity of the entire tree. Damage from splits, cavities, improper cuts, and decay fungi can compromise a trunk structurally long before visible signs appear at the canopy level. This collection covers trunk biology, notch-cutting and felling technique, split trunk assessment, stump and trunk removal options, and how trunk lean affects safe felling operations.
Reference Notes
- A tree trunk grows in diameter every year, adding a new ring of wood beneath the bark.
- The vascular cambium — a thin layer just beneath the bark — is responsible for all new trunk growth.
- Trunk cavities do not always indicate imminent failure but require professional assessment to determine risk level.
