Biology of Plantation Growth,g the early years of growth after seedlings are planted, the trees grow and expand the amounts of their leaves and fine roots until they reach a more or less constant total amount, determined by the amount of the resources required for growth available from the site, especially water and nutrients.

Growth Rates and Wood Quality,aracteristics that determine its quality are discussed. The silvicultural practices used in plantations may affect that quality. In particular, practices that increase tree growth rates, like weed control, thinning or fertilisation, may affect wood quality, particularly wood strength.

Thinning,d be chosen to achieve the best possible financial outcome for the plantation enterprise. Modern thinning regimes commonly involve two or three thinnings before 15–20?years of age, with 100–300 trees per hectare left after the final thinning. The final harvest then occurs at 25–30?years of age.
