| Research Abstract |
Damage of understory hardwoods, following selection logging in natural forests and thinning in planted forests, was investigated. Influence of logging damage to growth and survival of understory trees was also elucidated from the census of damaged trees in actual logging sites, and from artificial damage experiments. For selection logging in natural forest, small understory trees showed higher damage in both probability and intensity. Damaged trees decreased growth and survival, compared of non-damaged trees. For thinning in plantation, damage of understory trees was related thinning regime and type of machine used in operation.
