In Scandinavia, the producers of timber normally dry timber to a moisture content of 18% MC. However, after the studs are built into the wall structure, for example, they may become distorted as a result of further drying in the structure.
Many evergreen tree species of the rain forest become deciduous in this zone. Growing conditions are not so optimal, thus the tree canopy is lower (10-30m) than in the tropical rain forest and the trees less dense where drought is more extreme.pecies diversity is invariably lower than in nearby tropical rain forests. Environmental stress increases with instability (seasonality) of the environment, and fewer plants and animals can generate homeostatic mechanisms (for internal stability) to cope.
