response to wind loading. It is anatomically similar in some respects to tension wood.
The development of trunk taper and buttress roots are examples of loadresponsive (flexure) growth. On stems or branches, bulges or enlarged areas
may develop to compensate for higher load or loss of structural strength from
internal decay or other weakness. Near a crack, obvious response growth
may appear as spiraling or straight ribs.
Woundwood is produced in response to cambial damage. Woundwood is
typically denser than and chemically different from other wood, and it resists
decay better than normal wood. Its development also reinforces the strength
of wounded areas. If a wound or cavity is not readily closed due to the size
of the opening or other factors, woundwood may enlarge or curl inward at
the edge of the cavity (a feature commonly called a " ram's horn " ), adding
strength to the opening. The rate of woundwood development is partially
dependent upon tree health and species characteristics.
Trees develop more wood or stronger wood in some areas than is needed
to support the tree under normal load conditions-an internal safety factor.
The magnitude of the safety factor can vary significantly in different parts
of the tree and as a tree ages. This overdevelopment helps to support the
tree under extraordinary loads
of strong winds, snow, or ice.
