Tree fork

Wood grain pattern of a fork of Fraxinus excelsior (Common ash), as found by stripping off the outer and inner bark layers

An included bark junction formed in a wild cherry tree (Prunus avium)

A tree fork is a bifurcation in the trunk of a tree giving rise to two roughly equal diameter branches. These forks are a common feature of tree crowns. The wood grain orientation at the top of a tree fork is such that wood cells interlock to provide sufficient mechanical support. A common malformation of a tree fork is where bark has formed within the join and these bark-included junctions often have a heightened risk of failure.
