The base of a Yellow Birch trunk. In botany, the trunk (or bole) is the stem and main wooden axis of a tree, [1] which is an important feature in tree identification, and which often differs markedly from the bottom of the trunk to the top, depending on the species. The trunk is the most important part of the tree for timber production.
As the name suggests, this knot is often used by lumbermen and arborists for attaching ropes or chains to tree trunks, branches, and logs. [3] [5] For stability when towing or lowering long items, the addition of a half-hitch in front of the timber hitch creates a timber hitch and a half hitch, [6] or known as a killick hitch [2] when at sea.

Branch attachment in common ash Fraxinus excelsior L. Figure 1: Anatomical drawing of the wood grain of a branch attachment in a tree. Initially branches are mechanically attached to the trunks of trees by forming interlocking wood grain patterns at the top of the joint, within what is known as 'axillary wood' (Fig. 1). [1]

Girdling prevents the tree from sending nutrients from its foliage to its roots, resulting in the death of the tree over time, and it can also prevent flow of nutrients in the other direction depending on how much of the xylem is removed. A branch completely girdled will fail; and, when the main trunk of a tree is girdled, the entire tree will ...

A branch collar is the "shoulder" between the branch and trunk of woody plants; the inflammation formed at the base of the branch is caused by annually overlapping trunk tissue. [1] The shape of the branch collar is due to two separate growth patterns, initially the branch grows basipetally, followed by seasonal trunk growth which envelops the ...
