Bark stripping damage by red deer in a Sitka spruce forest in western Scotland III. Trends in wound condition

Bark stripping by red deer has been monitored at 40 sites in Glenbranter Forest, Argyll, since 1978, and the state of the 1173 wounds incurred has been recorded yearly. Despite deaths of trunks and felling, 70 per cent of the wounds are still extant.
Xylem was exposed and resin produced in the great majority of wounds. After 2 years new bark was developing on most wounds and after 8 years many wounds were completely healed. Large wounds greater than 180 cm2 in area had xylem exposed longer and healed more slowly than smaller wounds. Trees 20 or more years old at wounding had slower healing than younger trees, and about 10 per cent of the damaged trunks died. Many fraying and thrashing wounds occurred on trunks or trees that later died, but wounds of this origin which began to heal quickly became completely healed. Rots developed in only 1 per cent of the wounds, most of them greater than 180 cm2 in area. Although damage from bark stripping seems less serious than feared, timber defects may exist below apparently healed wounds.
