自1978年以来，在阿盖尔的格伦布兰特森林的40个地点监测了红鹿剥树皮的情况，每年记录了1173个伤口的情况。尽管树干和砍伐造成死亡，但70%的伤口仍然存在。木质部暴露，在绝大多数伤口中产生树脂。2年后，大多数伤口上都长出新的树皮，8年后，许多伤口完全愈合。面积大于180 cm的大伤口木质部暴露时间较长，愈合速度比小伤口慢。受伤时20年或20年以上的树木愈合速度比年轻的树木慢，大约10%的受损树干死亡。许多磨损和鞭打的伤口发生在后来死亡的树干或树木上，但这种起源的伤口开始愈合，很快就完全愈合了。只有1%的伤口出现腐烂，大多数伤口的面积超过180厘米。虽然剥树皮造成的损害似乎没有想象的那么严重，但在明显愈合的伤口下面可能存在木材缺陷。
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 cm 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 cm in area. Although damage from bark stripping seems less serious than feared, timber defects may exist below apparently healed wounds.
